Description

  The present invention relates to a medical image display device that performs display processing of medical images.

  In recent years, in medical institutions, a medical image management system called PACS (Picture Archiving and Communication System for Medical Application) that manages information such as medical images and personal medical records of patients as electronic data on a network has been developed. In addition, equipment for taking medical images of a subject is diversified, and various modalities such as an X-ray diagnostic apparatus, an X-ray CT apparatus, an MRI apparatus, an ultrasonic apparatus, a mammography, a PET apparatus, a SPECT apparatus, and an endoscope are provided. ing. Then, image viewers for browsing medical image data of these various modalities have been developed, and functions suitable for image diagnosis have been added or operability has been improved.

  By the way, interpretation of a medical image by a doctor often repeats a simple operation. For example, images having the same examination site and examination technique are interpreted in the same manner by arranging the images on the screen. In addition, images are often rearranged on the screen due to an increase in the number of images, and the time spent for such layout adjustment operations tends to increase during the interpretation time.

  Thus, for example, some of the above-mentioned viewers have a function of automatically arranging the layout of an image to be interpreted based on a predetermined protocol (hanging protocol). Further, in Patent Document 1, a “comparison interpretation” layout that displays images with different examination types and examination dates side by side in each monitor area and a “single interpretation” layout that displays only one image can be freely controlled by an operator's operation. The function to switch to is disclosed. In each of these layouts, whether to display the screen divisions side by side or one by one, whether to display a scout image (scanogram image), and when displaying a scout image, the slice position of the tomographic image is displayed as a line Various settings (settings for screen configuration, image arrangement state, image processing, etc.) such as whether or not to perform are performed in advance by the operator. Such setting information is managed by information called a tag.

  Next, the grouping condition 242, the layout holding information 243, and the routine registration condition 244 will be described with reference to FIGS.

As shown in FIG. 3, the grouping condition 242 is an image viewer terminal in which images having substantially the same inspection type and imaging condition are used as the same type of image regardless of the manufacturer and model (model) of each modality. This is a condition arbitrarily set by the operator in order to make the second control device 21 recognize. This grouping condition is set using tag information possessed by each medical image data.
Here, the tag is information described in an accompanying information area (for example, a header portion) of image data. The tag is described by a number representing each item and a value (tag information) representing the content of the item. For example, in DICOM (Digital Imaging and Communication in Medicine), a tag representing a modality is (0008, 0060), a tag representing an examination site is (0008, 0015), and a patient direction. The tag has a tag identification number for each item, such as (0020,4000). The contents of each tag are described as tag information. However, tag information often has a different value depending on the manufacturer and model, and the manufacturer may have a unique private tag.

The grouping condition 242 is, for example,
(1) Treat CT images of apparatuses A and B with different manufacturers as the same type.
(2) The series description “**” of the device A and the sequence name “xxx” of the device B are handled as the same type of series.
(3) When the series description of the created layout is “**”, the sequence name “XX” is also treated as matching.
It is a condition of the content.

The grouping condition 242 is set on the grouping condition setting screen 8 provided by the image viewer terminal 2, for example.
FIG. 3 shows an example of the grouping condition setting screen 8 and setting operation.

  The control device 21 extracts the tag information of a predetermined tag from the image data (images 241a, 241e, and 241h in the example of FIG. 3) selected by the operation of the operator, and creates the setting screen 8 for setting the grouping condition 242 To do. The extracted tag varies depending on the type of image. For example, some or all of the tags shown in Tables 1 and 2 below are extracted.

  In FIG. 3, an image 241a is captured by a model “a” manufactured by A company, an image 241e is captured by a model “b” manufactured by B company, and an image 241h is captured by a model “c” manufactured by C company. In the grouping condition setting screen 8, tag information for a plurality of tags (aaaa, bbbb), (cccc, dddd), (eeee, ffff), (gggg, hhhh) (iii, jjjj) is extracted from each image. Listed. Specifically, the tag information of the model “a” manufactured by the company A for the tags (aaaa, bbbb) is “X01”, the tag information of the model “b” manufactured by the company B is “Y01”, and manufactured by the company C. The tag information of the model “c” indicates “Z01”. Similarly, tag information is extracted from each image for other tags and displayed as a list in the grouping condition setting screen 8.

  When it is desired that the control device 21 recognize these images 241a, 241e, and 241h as the same type of image, the operator determines that the tag information listed in the grouping condition setting screen 8 is the same type of image. Specify the tag information to be referenced. The tag information to be specified may be one for each image, or a combination of a plurality of tag information. For example, as shown in FIG. 3, the control device 21 displays a mark M1 indicated by “Re” in the designated frame (tag information). The control device 21 recognizes the medical image data having one designated tag information or a combination of a plurality of tag information as images of the same type, and groups them.

  Specifically, in the example of FIG. 3, an image 241a photographed with a modality of a model “a” manufactured by A company, an image 241e photographed with a modality of a model “b” manufactured by B company, and a product manufactured by C company The image 241h photographed with the modality of the model “c” is originally an image photographed with the same inspection contents, but the way of holding the tag information is different because the manufacturer is different. It is assumed that the tag shown has the following description contents (1) to (3) in each image.

(1) In the image 241a, the tag (cccc, dddd) is described as “X02”, and the tag (eeee, ffff) is described as “X03”.
(2) In the image 241e, the tag (aaaa, bbbb) is described as “Y01” and the tag (cccc, dddd) as “Y02”.
(3) In the image 241h, the tag (aaaa, bbbb) is described as “Z01”, the tag (cccc, dddd) as “Z02”, and the tag (eeee, ffff) as “Z03”.

In such a case, in order to recognize the images 241a, 241e, and 241h as the same image, those tag information is designated as the grouping condition 242.
When the control device 21 displays an image, the grouping condition 242 is referred to, and if the tag information of the image to be displayed satisfies these grouping conditions 242, what kind of image is the same as the type of inspection? It becomes possible to recognize. Therefore, when there is a layout or the like set in advance for each inspection type, display according to the layout can be performed. The layout display (reproduction) will be described later.

  The grouping condition 242 set in this way is stored in the storage device 24 of the image viewer terminal 2. Moreover, you may make it register in the database 35 of the server 3 according to operation of an operator.

Further, a plurality of grouping conditions 242 are generated for each modality type (for example, CT image, MR image, MG image) in addition to the inspection type and imaging conditions.
The grouping condition 242 is preferably set before the layout or routine is set. However, the grouping condition 242 may be set anew during the layout or routine setting or during the interpretation (display processing), or added for a desired image. It may be settable.

In the example of FIG. 3, an example is shown in which a grouping condition 242 is set by specifying a combination of a plurality of tags for each image. However, as long as one tag can specify the type of inspection of the image. The grouping condition 242 can be set with one tag.
Further, when adding an image to be grouped, by dragging and dropping the image into the grouping condition setting screen 8, a list of tag information about the image is added, and desired tag information may be designated. .
Image grouping may be performed in series units or in image units. Further, the operability can be improved by arranging a button for specifying all items in the tag information, a button for canceling all items, and the like so that the batch operation can be performed.

  In addition, as the grouping condition 242, a grouping condition that is preferably proposed in advance may be provided as a default condition, and the operator may arbitrarily specify tag information for the default condition.

  When the search condition is input by the operator on the image search screen 71 and the “search” button 76 is pressed, the control device 21 transmits the input search condition to the server 3. The server 3 searches the database 35 for image data based on the search condition, and transmits the search result data to the image viewer terminal 2 that is the search condition transmission source (step S102). The image viewer terminal 2 displays the search result data transmitted from the server 3 in the search result display area 77 (step S103).

  FIG. 8B shows an example of a search result display screen. The search result display area 77 displays a list of image data that matches the search conditions. On the search result display screen, desired image data is selected by the operator's operation (step S104), and when the "image display" button 78 is pressed, the control device 21 selects the image selected for the server 3. Send a data acquisition request. The server 3 transmits the requested image data to the requesting image viewer terminal 2. The image viewer terminal 2 stores the received image data in the storage device 24 and displays the image display screen 9 (see FIG. 9) on the monitor 22 (step S105).

  FIG. 9 shows an example of the image display screen 9. The image display screen 9 in this example has an image list display area 91 for displaying subject information 911, a list of search result images (thumbnail bar) 912, and the like, and routine setting, layout setting, or grouping condition 242 described later. There are provided a menu bar 92 that is operated when performing settings and the like, and a view area 93 on which medical images and various setting screens are displayed.

  The images acquired in steps S101 to S104 are displayed in the image list display area 91. In the example of FIG. 9, a plurality of acquired images 241a, 241b,... Are displayed as thumbnails (reduced).

  In the grouping condition setting process of FIG. 10, the control device 21 first displays the grouping condition setting screen 8 on the monitor 22 (step S201; see FIG. 3).

  The control device 21 extracts tag information corresponding to the type of the image from the image selected by the operation of the operator, and creates a list in the grouping condition setting screen 8. For example, when a desired image is selected and moved from the thumbnail bar 912 to the empty frame (initial display form) of the grouping condition setting screen 8 by a mouse drag and drop operation or the like (step S202), the control device 21 extracts predetermined tag information from the image and creates a tabular grouping condition setting screen 8 as shown in FIG. 3 (step S203).

  Next, when tag information for which a grouping condition is to be set is selected by a mouse click operation or the like, the control device 21 displays a mark M1 on the selected tag information. The control device 21 recognizes the image having the selected tag information (one or a plurality of combinations) as the same type image (step S204).

  The grouping condition 242 set in this way is stored in the storage device 24 (step S206) by pressing the “save” button 926 on the image display screen 9 in FIG. 9 (step S205). Further, when an image of a different type is selected, a grouping condition setting screen 8 for the image of that type is generated and displayed, and a setting operation for the grouping condition 242 is accepted.

  When the setting of the grouping condition 242 between images is completed by the processing in steps S201 to S206 as described above, the control device 21 returns to the image search / setting processing in FIG. 4 and proceeds to step S108.

  The control device 21 displays a screen for inquiring the operator whether or not to register the set grouping condition 242 in the server 3 on the monitor 22, and when an instruction to register in the server 3 is input by the operation of the operator ( In step S108, the control device 21 of the image viewer terminal 2 transmits the registered grouping condition 242 to the server 3 via the communication I / F 26 (step S109). The server 3 registers the grouping condition 242 transmitted from the image viewer terminal 2 in the database 35.

  The grouping conditions 242 registered in the database 35 of the server 3 can be shared by all the image viewer terminals 2 in the medical image management system 1. That is, each image viewer terminal 2 acquires the grouping condition 242 registered in the server 3, thereby making various images as the same type of image based on the grouping condition 242 set and registered in the other image viewer terminal 2. The layout can be reproduced. If the operator wants to use his / her own grouping condition 242, he / she may not register it in the server 3 and make it private.

  When the “layout” button 923 of the menu bar 92 is pressed by a mouse click operation or the like on the image display screen 9 in FIG. Is started (step S111).

In the layout setting process of FIG. 11, first, the control device 21 accepts selection of an image to be displayed in the view area 93 of the image display screen 9 (see FIG. 9) (step S301). For example, among the images displayed on the thumbnail bar 912 of the image display screen 9 in FIG. 9, the image “2008.12.05”, the image “2008.12.12”, and the image “2008.12.12” are displayed. Are first displayed in a predetermined layout in the view area 93 based on an initial display protocol (hanging protocol) (step S301). Details of the initial display of the image are described in Japanese Patent Application Laid-Open No. 2005-73818, and the description thereof is omitted.
It should be noted that the comparison of the relative inspection dates and times of a plurality of images is performed at the time of image selection.

  Thereafter, a screen configuration such as a monitor configuration and the number of screen divisions is set by an operator's operation (step S302), an image layout is set (step S303), and reversal processing, FOV processing, Various image processing such as 3D processing and cine display processing are set (step S304).

  When the setting of the layout is completed by the processing of step S301 to step S304 and the “save” button 926 on the menu bar 92 is pressed (step S305; Yes), the control device 21 displays the layout save screen 10 shown in FIG. It is displayed (step S306).

FIG. 12 shows an example of the layout saving screen 10.
The layout saving screen 10 displays a reduced image 101 of the screen state (layout) of the current view area 93 and a confirmation message 102. Further, an input frame 103 for inputting a layout name, a selection field 104 for selecting a routine creation destination, and a “create new routine” button 105 that is pressed when creating a new routine are displayed. Routine registration / creation will be described later. When temporarily saving the current layout, “temporary save” is selected from the selection column 104 and the “register” button 106 is pressed (step S307).

  When the current layout is stored as a part of the routine, a desired routine is selected from the selection field 104 or a routine is created by pressing the new routine creation button 105 and then a “Register” button 106 is created. Is pressed (step S307). Through these operations on the layout saving screen 10, the layout holding information 243 for the layout is stored in the storage device 24.

  When the layout is saved as “temporary save”, the temporarily saved layout UID information 2436 (study instance UID, series instance UID, SOP instance UID) shown in Table 5 is held as information for specifying the arrangement image. To do. Further, when the layout is stored in the “routine”, the image arrangement specifying series information 2433 and the image arrangement specifying image information 2434 shown in Tables 1 and 2 are held as information for specifying the arrangement image. .

  When the setting of the layout is completed by the processing of step S301 to step S307, the control device 21 of the image viewer terminal 2 returns to the image search / setting processing of FIG. 7 and proceeds to step S108.

  The control device 21 displays on the monitor 22 a screen for inquiring the operator whether or not to register the set layout holding information 243 in the server 3. When an instruction to register in the server 3 is input by the operation of the operator (step S108), the control device 21 of the image viewer terminal 2 transmits layout holding information 243 to the server 3 via the communication I / F 26. (Step S109). The server 3 registers the layout holding information 243 transmitted from the image viewer terminal 2 in the database 35.

  The layout holding information 243 registered in the database 35 of the server 3 can be shared by all the image viewer terminals 2 of the medical image management system 1. That is, each image viewer terminal 2 acquires the layout holding information 243 registered in the server 3, thereby displaying an image layout based on the layout holding information 243 set and registered in the other image viewer terminal 2. Is possible. If the operator wants to keep his / her own layout holding information 243 private, it may not be registered in the server 3.

  When the “routine” button 922 of the menu bar 92 is pressed by a mouse click operation or the like on the image display screen 9 in FIG. 9 (step S106 in FIG. 7; No → Step S110; No → Step S112; Yes), control is performed. The device 21 starts the routine setting process shown in FIG. 13 (step S113).

In the routine setting process of FIG. 13, the control device 21 first displays the routine registration screen 15 (step S401).
FIG. 14 is a diagram showing an example of the routine registration screen 15.
In the routine registration screen 15 of this example, a temporary storage layout list 151 for displaying a list of layout holding information 243 temporarily stored in the storage device 24, a pull-down list 152 for selecting a routine name, and a new routine are created. “Create New Routine” button 153 to be pressed, routine detail display field 154 for displaying a list of layouts included in the routine, “Add” button 155, “Delete” button 156, “Register” button 157, “Cancel” button 158, A “to top” button 159, a “up” button 160, a “down” button 161, a “to last” button 162, and the like are provided.

  The control device 21 displays the layout holding information 243 temporarily stored in the storage device 24 in the temporary storage layout list 151 (step S402). At this time, if thumbnail images of each layout are displayed, the layout can be easily confirmed.

  And the control apparatus 21 sets a routine by operation of an operator (step S403). Specifically, for example, when a created routine name is selected from the pull-down list 152, the control device 21 reads the routine registration information 244 of the selected routine from the storage device 24 and is set. Information of each layout (thumbnail image, layout name, etc.) is displayed in the routine detail display field 154 in the order. When the new routine creation button 153 is pressed, a routine name input screen (not shown) is displayed and a new routine is created. In this case, nothing is displayed in the routine detail display field 154 at this stage.

  When a layout is selected from the temporarily saved layout list 151 on the routine registration screen 15 and the “add” button 155 is pressed, the selected layout is added to the selected routine or the routine being created. The order of addition can be appropriately rearranged by operating the “up to top” button 159, the “up” button 160, the “down” button 161, the “to last” button 162, and the like. It is assumed that the layout registered in the routine is deleted from the memory area of the temporary storage layout and stored as the in-routine layout.

  When the temporary storage layout is added to the intra-routine layout, the control device 21 reproduces the information specifying the arrangement image to the image level based on the temporary storage layout UID information 2436 of the layout holding information 243. That is, the image arrangement specifying series information 2433 and the image arrangement specifying image information 2434 are acquired and held as information for specifying the arrangement image.

  Further, when a layout is selected from the routine detail display field 154 of the routine registration screen 15 and the “delete” button 156 is pressed, the selected layout is moved to the temporary storage layout.

  When the routine setting operation as described above is performed on the routine registration screen 15 and the “registration” button 157 is pressed (step S404; Yes), the control device 21 of the image viewer terminal 2 is set in the routine detail field 154. The layout holding information and the order information of each layout are updated and registered (step S405).

  When the setting of the routine is completed by the processing of step S401 to step S405, the control device 21 of the image viewer terminal 2 returns to the image search / setting processing of FIG. 7 and proceeds to step S108.

  The control device 21 displays on the monitor 22 a screen for inquiring the operator whether or not to register the set routine registration information 244 in the server 3. When an instruction to register with the server 3 is input by the operation of the operator (step S108; Yes), the control device 21 of the image viewer terminal 2 sends the routine registration information 244 to the server 3 via the communication I / F 26. Transmit (step S109). The server 3 registers the routine registration information 244 transmitted from the image viewer terminal 2 in the database 35.

  The routine registration information 244 registered in the database 35 of the server 3 can be shared by all the image viewer terminals 2 in the medical image management system 1. That is, each image viewer terminal 2 acquires routine registration information 244 registered in the server 3, thereby performing routine display of images based on the routine registration information 244 set and registered in other image viewer terminals 2. Is possible. If the operator wants to make his / her routine registration information 244 private, it may not be registered in the server 3.

  When the “end” button 927 of the menu bar 92 is pressed by a mouse click operation or the like on the image display screen 9 in FIG. 9 (Step S106 in FIG. 7; No → Step S110; No → Step S112; No → Step S114 in FIG. 7). ; Yes), the control device 21 ends the series of image search / setting processing.

Next, display processing in the image viewer terminal 2 will be described with reference to FIG.
Prior to the execution of this display process, a grouping condition setting process (see FIG. 10), a layout setting process (see FIG. 11), and a routine setting process (see FIG. 13) are performed. It is assumed that information 243 and routine registration information 244 are stored.

  First, the control device 21 of the image viewer terminal 2 accepts an image selection operation (step S501). The image is selected in the same manner as steps S101 to S105 of the image search / setting process shown in FIG. When the image selection (search) is completed, an image display screen 9 shown in FIG. 9 is displayed.

  When the “routine” button 922 is operated after selecting “classification” 921 from the menu bar 92 on the image display screen 9 in FIG. 9, the control device 21 displays a list 98 of routines registered in the storage device 24. (Step S502). A display example of the routine list 98 is shown in FIG. In the example of FIG. 16, “routine A”, “routine B”, “routine C”, and “routine D” stored in the storage device 24 are listed as a routine list 98. In addition, when “routine A” is selected by a mouse operation or the like in the display example of FIG. 16, the layouts included in the routine A may be displayed in a list according to the order (layout list 99 of FIG. 16). .

  At this stage, when “routine A” is designated from the list 98 and the list 99, the control device 21 uses the image selected in step S501 in the view area 93 of the image display screen 9 to display the first “routine A”. Reproduce the layout “Layout 1”.

That is, first, the control device 21 initializes a counter n for counting the layout order to “1”, and sets the upper limit number N to the number of layouts included in the “routine A”. Next, the control device 3 applies the layout holding information 243 to the selected image.
At this time, the control device 21 determines the image type based on the grouping condition 242 for the selected image (step S506).

  Specifically, the control device 21 reads the screen configuration information 2431 from the layout holding information 243 of the first layout “layout 1”, and sets the screen configuration such as the monitor group and the number of screen divisions based on the screen configuration information 2431. Reproduce. Also, an image to be arranged in each divided screen area is acquired. In order to specify the image to be arranged, the control device 21 makes a determination with reference to the image arrangement specifying series information 2433, the image arrangement specifying image information 2434, and the relative inspection date / time comparison information 2435 of the layout holding information 243.

  At this time, the control device 21 refers to the tag information of the plurality of images selected as the display target, and based on the grouping condition 242 stored in the storage device 24, selects the type of image to be displayed in each divided screen area. Identify. For example, if an image shot with the shooting condition “x” is arranged in a certain divided screen area and a layout is set, an image having the same shooting condition as the shooting condition “x” (same kind of image) ) Are selected from the selected images. Therefore, even if the image arranged in this display process is an image having tag information different from that at the time of layout setting, the image is recognized and set as the same kind of image by the grouping condition 242, and thus the layout can be reproduced.

  Further, the control device 21 performs image processing on the arranged image based on the image processing information 2432 held in the layout holding information 243. When the screen is divided into a plurality of areas and images having different examination dates / times are displayed in each area, the control device 21 determines whether the selected image is the “current image” or “previous image” based on the relative examination date / time comparison information 2435. ".

  As described above, the control device 21 lays out the image selected based on the layout holding information 243 and the grouping condition 242 at an appropriate arrangement position (step S507).

Next, when the “→” button 923 on the menu bar 92 is pressed (step S508; Yes), the control device 21 adds 1 to the counter n (step S509), and the value of the counter n is the upper limit N of the number of layouts. Is determined (step S510).
When there is a next layout (when the counter n has not reached the upper limit N), the process returns to step S506, and the layout holding information 243 of the nth layout is applied to the selected image. At this time, similarly, the grouping condition 242 is determined for the selected image.

  When the “←” button 924 of the menu bar 92 is pressed (Step S508; No → Step S511; Yes), the control device 21 subtracts 1 from the counter n (Step S512), and the value of the counter n is 1 or more. In the case (step S513; No), the process returns to step S506, and the layout holding information 243 of the nth layout is applied to the selected image. At this time, similarly, the grouping condition 242 is determined for the selected image.

  If the counter n exceeds the upper limit number N of the number of layouts by pressing the “→” button 923 or the “←” button 924 (step S510; No), or the counter n becomes less than 1 (step S513; Yes). Since there is no corresponding layout, the current display state is maintained.

When the “layout” button 923 is pressed from the menu bar 92 in step S502 (step S514; Yes), the control device 21 displays a list 99 of layout holding information 243 stored in the storage device 24 (step S515; (See FIG. 16). When a desired layout is designated from the layout list 99 (step S516), the control device 21 applies the layout holding information 243 of the designated layout to the selected image. At this time, the control device 21 determines the grouping condition 242 for the selected image, thereby specifying an image to be arranged as an image of the same type as that at the time of layout setting in each divided screen area (step S517).
The control device 518 reproduces the selected image into a layout according to the designated layout holding information 243 (step S518).

  Thereafter, the processes in steps S502 to S518 are repeated until an end instruction is input. If an end instruction is input (step S519; Yes), the display process ends.

  It should be noted that the image displayed by the above-described display processing can be further subjected to image processing or layout editing operation. The layout edited at this stage can be further saved as a temporary save layout by operating the “Save” button 926.

Next, layout setting and routine setting will be described with reference to FIGS. 17 to 22 using specific examples.
The following example shows an example in which the processing performed in the present embodiment is applied when comparative interpretation of a mammo image (hereinafter referred to as MG image) is performed in the image viewer terminal 2.

  In order to perform comparative interpretation of the MG image of the subject “HITACHI HANAKO”, first, the interpreting physician uses the search screen 71 on the examination image of June 5, 2006 (this time) and the examination of June 1, 2005. Select the image (previous) and display the image. Here, it is assumed that the current image includes four images of RCC, LCC, RMLO, and LMLO. Similarly, the previous image includes four images of RCC, LCC, RMLO, and LMLO. These MG images are all MG images taken by the modality of manufacturer A.

  As shown in FIG. 17A, the image interpretation doctor sets the left and right monitors as one monitor group in one virtual area, and sets the image layout to STACK 2 × 2. RCC (current) is displayed in the upper left area of the left monitor, LCC (current) in the upper right area, RMLO (current) in the lower left area, and LMLO (previous) in the lower right area. Also, RCC (previous) is displayed in the upper left area of the right monitor, LCC (previous) is displayed in the upper right area, RMLO (previous) is displayed in the lower left area, and LMLO (previous) is displayed in the lower right area. Further, the left and right images in the upper right / lower right area and the upper right / lower right area of the left monitor are reversed so that adjacent images are back-to-back. Thereafter, the layout save screen 10 (see FIG. 12) is displayed by pressing the “save” button 925, and the layout name “mammo comparison / whole” is entered and registered as a temporarily saved layout.

  FIG. 17B shows an example of the content of information held as the layout holding information 243 for the layout “mammo comparison / whole”. For example, information on the screen configuration (screen division areas), information for specifying images to be arranged in each area (arranged images), information on image arrangement states (display mode, etc.), information on image processing (rotation / Inversion) and the like are held as layout holding information 243, respectively. Further, as shown in FIG. 17C, the information specifying the image is held in the form of tag information with respect to contents such as the type of modality of each image, imaging conditions, and patient part.

  Next, as shown in FIG. 18, the interpretation doctor sets STACK2 × 1 while setting the left and right monitors as one monitor group in one virtual area. RCC (current) is displayed in the left area of the left monitor, RCC (previous) is displayed in the right area, LCC (current) is displayed in the left area of the right monitor, and LCC (previous) is displayed in the right area. Further, the left and right images of the right area of the left monitor and the right area of the right monitor are reversed so that adjacent images are back to back. After that, the layout save screen 10 is displayed by pressing the “save” button 925, and the layout name “mammo comparison / CC” is input and registered as a temporarily saved layout (FIG. 18A). The layout holding information 243 held at this time is shown in FIG. 18B, and the tag information of the image is shown in FIG.

  Next, as shown in FIG. 19, the image interpretation doctor sets STACK2 × 1 while setting the left and right monitors as one monitor group in one virtual area. RMLO (current) is displayed in the left area of the left monitor, RMLO (previous) is displayed in the right area, LMLO (current) is displayed in the left area of the right monitor, and LMLO (previous) is displayed in the right area. Further, the left and right images of the right area of the left monitor and the right area of the right monitor are reversed so that adjacent images are back to back. After that, the layout saving screen 10 is displayed by pressing the “save” button 925, and the layout name “mammo comparison / MLO” is input and registered as a temporarily saved layout (FIG. 19A). The layout holding information 243 held at this time is shown in FIG. 19B, and the tag information of the image is shown in FIG. 19C.

  Further, the “routine” button 922 is pressed on the image display screen 9 to display the routine registration screen 15 (see FIG. 14), and “mammo comparison / overall” and “mammo comparison / CC” registered as “temporary storage layout”. The order of “mammo comparison / MLO” is rearranged in the order of “mammo comparison / overall” → “mammo comparison / MLO” → “mammo comparison / CC”, and the routine name is set to “mammo comparison”. FIG. 20 shows a layout included in the routine “mammo comparison” and its order.

Next, the interpretation doctor performs comparative interpretation of the MG image of the subject “HITACHI SAORI”. On the search screen 71, the radiogram interpreter uses the examination image of the subject “HITACHI SAORI” on July 15, 2006 (current) and the examination image on July 20, 2005 (previous). Select to display an image.
Here, it is assumed that the current image includes four images of RCC, LCC, RMLO, and LMLO. Similarly, the previous image includes four images of RCC, LCC, RMLO, and LMLO. These MG images are taken with the modality of manufacturer B, and the tag information to be described is different from those taken with the modality of manufacturer A.

  For example, the RCC image of the image of the subject “HITACHI HANAKO” shown in FIG. 17C has tag information “w” (the tag may be one or a plurality of combinations) with respect to the imaging condition of interest. However, it is assumed that the RCC image of the image of the subject “HITACHI SAORI” shown in FIG. 21A describes the imaging condition with tag information “w2”. The photographing conditions “w” or “W2” are grouped according to the grouping condition 242. That is, although the description contents of the tags are different, they are grouped as images of the same type. Similarly, for LCC, RMLO, and LMLO, it is assumed that the image of manufacturer A and the image of manufacturer B are grouped.

After the image is initially displayed, the interpretation doctor displays a list of creation routines by pressing the “routine” button 922, and selects “mammo comparison” from the list.
The control device 21 acquires the layout holding information 243 of the first layout “mammo comparison / overall” of the routine “mammo comparison” from the storage device 24. Further, the control device 21 refers to the tag information of the selected image, determines the grouping condition 242, and specifies the image to be displayed in each area. The grouping condition 242 is determined with reference to tag information attached to the “HITACHI SAORI” image (manufacturer B), the same kind of image is specified, and displayed at the corresponding image position. As a result, an image grouped as the same type as the RCC image displayed in the upper left area when the layout is set is displayed in the upper left area when the layout is reproduced.

  The control device 21 reproduces the layout based on the layout holding information 243 of the first layout “mammo comparison / whole” of the routine “mammo comparison”. Specifically, as shown in FIG. 22A, the monitor setting is set to “one virtual area with both the left and right monitors as one monitor group”, and the arrangement information is set to “STACK2 × 2”. RCC (current) is displayed in the upper left area of the left monitor, LCC (current) in the upper right area, RMLO (current) in the lower left area, and LMLO (current) in the lower right area. Also, RCC (previous) is displayed in the upper left area of the right monitor, LCC (previous) is displayed in the upper right area, RMLO (previous) is displayed in the lower left area, and LMLO (previous) is displayed in the lower right area. Also, the left and right images of the upper right and lower right areas and the upper right and lower right areas of the left monitor are reversed.

  The image interpretation doctor may perform image processing such as “Window L / W”, “FOV”, “magnifying glass”, and “measurement” in order to display the image in an easy-to-see manner at this stage. In addition, a change in the number of screen divisions, a change in image arrangement (tile / stack), and the like may be performed.

  Next, when the “→” button is pressed by the operation of the image interpretation doctor, the next layout “mammo comparison / MLO” is reproduced. As shown in FIG. 22B, the control device 21 sets the monitor setting to “one virtual area with the left and right monitors as one monitor group”, and sets the image arrangement to “STACK2 × 1”. Further, the control device displays RMLO (current) in the left area of the left monitor, RMLO (previous) in the right area, LMLO (current) in the left area of the right monitor, and LMLO (previous) in the right area. Further, the left and right images of the right area of the left monitor and the right area of the right monitor are reversed so that adjacent images are back to back.

  Next, when the “→” button is pressed by the operation of the interpretation doctor, the next layout “mammo comparison / CC” is reproduced. As shown in FIG. 22C, the control device 21 sets the monitor setting to “one virtual area with the left and right monitors as one monitor group”, and sets the image arrangement to “STACK2 × 1”. The control device 21 displays RCC (current) in the left area of the left monitor, RCC (previous) in the right area, LCC (current) in the left area of the right monitor, and LCC (previous) in the right area. Further, the left and right images of the right area of the left monitor and the right area of the right monitor are reversed so that adjacent images are back to back.

  Finally, when the image interpretation doctor again selects the layout “mammo comparison / overall” from the layout list 99 (see FIG. 16) in order to refer to the entire current / previous image again, the control device 21 displays FIG. ) Based on the layout holding information 243, the monitor setting is set to “one virtual area with both the left and right monitors as one monitor group”, the arrangement information is set to “STACK2 × 2”, and the left monitor RCC (current) is displayed in the upper left area, LCC (current) in the upper right area, RMLO (current) in the lower left area, and LMLO (current) in the lower right area. Also, RCC (previous) is displayed in the upper left area of the right monitor, LCC (previous) is displayed in the upper right area, RMLO (previous) is displayed in the lower left area, and LMLO (previous) is displayed in the lower right area. Also, the left and right images of the upper right and lower right areas and the upper right and lower right areas of the left monitor are reversed.

  When the above routine display is performed and the interpretation is completed, and the “End” button is pressed by the interpretation doctor, the control device 21 switches the display screen to the search screen and ends the display process.

As described above, the medical image display apparatus (image viewer terminal 2) of the present embodiment extracts predetermined tag information from a plurality of different types of medical image data, and the extracted tag information is between the types. Even if they are different, it is possible to set a grouping condition 242 for grouping them as images of the same type. For this reason, it is possible to recognize images of different manufacturers, model numbers, shooting conditions, and the like as the same type of image.
Further, the control device 21 provides a grouping condition setting screen 8 for the operator to set the grouping condition 242, and the medical device having one tag information or a combination of a plurality of tag information specified on the grouping condition setting screen 8. Since the image data is grouped as the same kind of image, the operator can set the grouping condition 242 with a simple operation.

  When a plurality of images are laid out in a display screen, layout holding information 243 including information such as a screen configuration, an image arrangement state, image processing, or image specifying information is held for each layout. Therefore, when the image is displayed again with the same layout, not only the reproduction is easy, but also by determining the grouping condition 242 described above, it is the same even if the image is different in manufacturer, model number, photographing condition, etc. The layout can be reproduced by recognizing the image as the type of inspection.

  Furthermore, since the image viewer terminal 2 can combine a plurality of layouts and register the order as a routine, the layout can be reproduced in the registered order at the time of interpretation. Therefore, it is not necessary to repeat the layout setting for each interpretation, and the work load is greatly reduced. In particular, it is possible to easily switch to the layout in the order of the front and back by a simple operation such as pressing the feed button of the layout such as the “→” button or the “←” button, so that the interpretation efficiency is improved.

  Further, if the grouping condition 242, layout holding information 243, and routine registration information 244 created in each image viewer terminal 2 are accumulated and stored in the server 3, the image layout and routine can be stored in the entire medical image management system 1. And tag grouping conditions can be shared.

  It is not always necessary to register the grouping condition 242, layout holding information 243, routine registration information 244 and the like in the server 3. That is, each image viewer terminal 2 may have various display layouts and routines according to the interpretation of the interpreter.
