Description

  The present invention relates to a medical image storage apparatus that stores medical images and provides image data to a predetermined destination.

  The medical image storage device is a device for storing a medical image of a part of a subject imaged by a medical image imaging apparatus (modality) such as an X-ray tomography apparatus (CT) or a magnetic resonance imaging apparatus (MRI). As this medical image storage device, for example, a device that is connected to a medical image photographing device, a medical report creation support device, and an image display device via a network such as a LAN and constructs a medical image storage system (PACS) is known. (For example, refer to Patent Document 1).

  The image data generated by the image capturing device normally conforms to the DICOM (Digital Imaging and Communication in Medicine) standard, and the image display device uses a medical image based on the image data defined by the DICOM standard. Is displayed. This image data is stored and managed by a medical image storage device.

  In general, single-frame image data having an image (image) of one frame (only one image) is used as the image data. However, in recent years, a plurality of images are used for the purpose of transmitting and receiving a large amount of images at high speed. Multi-frame image data such as enhanced image data having the following characteristics has been used.

  Here, examples of the single frame image data include image data in which incidental information is combined with a cross-sectional image of one frame (one frame). On the other hand, the enhanced image data includes, for example, image data in which common supplementary information is combined with a plurality of cross-sectional images.

These image data can be reconstructed from a part of the data by, for example, compressing the image data in the JPEG2000 format. In the acquisition of large-size image data using the HTTP protocol, the display start time can be shortened by displaying the image with only a part of the acquisition.

  However, the above technique has the following problems. That is, in the case of enhanced image data in which image data of a plurality of frames is stored, in order to display the image of the subsequent frame, the enhanced image data cannot be displayed until all the reading is completed, and the feature of JPEG2000 compression is utilized. I can't. In addition, when measurement information or annotations are added to a part of recent enhanced image data stored in hundreds or thousands of images, even if the image display device wants to display the image, the target frame You must read everything up to. Therefore, it takes a long time to obtain and display the target frame from the storage device. Furthermore, depending on the image display device of the provision destination, the enhanced image data may not be supported, and the medical image in the enhanced image data cannot be accurately displayed.

  In view of this, a method is provided in which all received enhanced image data is divided to create single frame image data and stored separately. However, single frame image data corresponding to all enhanced image data is stored. This increases the amount of data to be stored.

  The received image determination unit 61 shown in FIG. 2 determines whether or not the received image data is enhanced image data. When the received image data is enhanced image data, the virtual specifying information generating unit 62 generates virtual specifying information.

  The virtual specific information generation unit 62 extracts frame information of enhanced image data, and generates virtual specific information for search and virtual specific information for image generation. The virtual specific information includes, for example, virtual DICOM image UID (virtual UID), extraction position, size, etc. for each frame (image) as information on the frame. The virtual UID is individually assigned for each frame, and is set to a number associated with the UID of the original enhanced image data, for example. The generated virtual specific information is stored in the database 53 as information regarding the enhanced image data D1.

  The registration unit 63 registers the image data (enhanced image data and single frame image data), the accompanying information J1 and J2, and the specific information thereof in the database 53 and the image data storage unit 54. Specifically, image data and incidental information are registered in the image data storage unit 54, and file paths that are specific information thereof are registered in the database 53.

  The database 53 manages identification information for identifying the type of examination to be performed, image data storage locations, and the like. For example, the database 53 stores file paths of various data such as enhanced image data and single frame image data registered in the image data storage unit 54. Further, the virtual specific information generated by the virtual specific information generating unit 62 is stored in the database 53.

  The image data storage unit 54 receives image data such as enhanced image data D1 and single frame image data D2, writes it in an appropriate location, and stores it. Further, the image data storage unit 54 communicates with the database 53 to correct the database 53 when the storage location is determined, the image data in the storage location is deleted, or the storage location is changed. Do. As the image data storage unit 54, for example, a hard disk drive, NAS (Network Attached Storage), or the like can be used.

  The counterpart determination unit 64 acquires the corresponding image type information of the connected device such as the medical image display device 4 and determines whether the counterpart (providing destination) is a model corresponding to the enhanced image data.

  The search data generation unit 65 is an image list for the user to specify a target image based on the determination by the destination determination unit 64 when there is a browsing request (provision request) from the medical image display device 4. Generate search data for.

  For example, when the medical image display device 4 is compatible with enhanced image data, the specific information about the relevant enhanced image data and single frame image data to be searched, and the virtual specific information about the enhanced image data Both are searched and based on these, search data is generated.

  On the other hand, when the medical image display device 4 is a model that does not support enhanced image data, the search data is obtained from identification information other than enhanced image data, that is, identification information of single frame image data and virtual identification information about enhanced image data. Generate. The generated search data is sent from the transmission unit 55 to the medical image display device 4 and displayed in a list format, for example.

  Therefore, the user can designate the enhanced image data for each frame, that is, as single data by referring to the search data in the list format. In a model that can handle enhanced image data, a plurality of frames can be specified together, that is, specified as normal enhanced image data. Furthermore, designation for each frame includes designation of the order of a plurality of frames in enhanced image data, for example, so as to sort them in a predetermined order.

  Based on the information from the medical image display device 4, the designated image determination unit 66 determines the image type to be provided that is specified by the user based on the search data, for example.

  When the designated image data, that is, the provided image data relates to the virtual identification information, the single image data generation unit 67 generates the corresponding enhanced image data from the virtual UID or virtual path of the designated virtual identification information. Among them, a target frame is extracted, and a single processing for generating single frame image data is performed. Also, for the image data to be singulated, additional information J2 associated with the additional information J1 of the original enhanced image data D1 is added to the generated single frame image data D2. For example, at least a part of the incidental information included in the multiframe image data is included in the incidental information of the generated single frame image data.

  The display data generation unit 68 generates display data to be sent to the medical image display device 4 in response to a provision request from the medical image display device 4. Here, for example, in the case where the provided image data is not a target for singleization, display data is generated from the stored image data and specific information of the designated image.

  Hereinafter, a medical image storage operation and a medical image display operation performed by the medical image storage device 5 will be described with reference to FIGS.

  First, processing in the medical image storage device 5 from reception of image data captured by the medical image capturing device 2 to storage will be described with reference to FIG.

  When the receiving unit 51 receives the image data from the medical imaging apparatus 2 (ST11), the received image determining unit 61 extracts the incidental information of the image (ST12), and the type of the received image, that is, the received image. It is determined whether the data is enhanced image data or single frame image data (ST13).

  When it is determined that the received image data is the enhanced image data D1 (Yes in ST13), the virtual specific information generation unit 62 extracts the frame information of the image data (ST14) and generates virtual specific information. (ST14). The virtual identification information includes search information such as a file path and management information. Here, based on the frame information and the like of the image data, for each frame image, the generated virtual UID, the number of frames, the extraction position, the size, and the like are generated as virtual specific information. The UID given to the virtual image includes, for example, an inspection UID set using the inspection UID of the original image, a series UID, and an image UID. For example, for a series UID, if the group to which a frame belongs differs depending on the frame position, a different series UID is issued.

  The generated virtual identification information is registered in the database 53 by the registration unit 63 (ST16) and stored in the database 53. The medical image storage device 5 stores the enhanced image data D1 and the accompanying information J1 in the image data storage unit 54 (ST17), and registers the specific information in the database 53 (step S18). The specific information includes search information such as a file path and management information, for example.

  On the other hand, when it is determined in ST13 that the received image data is not enhanced image data, that is, single frame image data D2 (No in ST13), the virtual specific information is not generated, and the single frame image data The supplementary information J2 of the single frame image data is stored as it is in the image data storage unit 54 (step S17), and specific information such as the file path of the single frame image data is registered in the database 53 (step S18).

  Next, processing of the medical image storage device 5 from receiving a search request from the medical image display device 4 to transmitting search data will be described with reference to FIG.

  When a search request is received by the receiving unit 51 in response to a user instruction input or the like in the medical image display device 4 (ST21), the partner determination unit 64 displays a partner, that is, a medical image based on the corresponding image type information of the connected device. It is determined whether or not the device 4 is a model corresponding to the enhanced image (ST22).

  If it is determined in ST22 that the medical image display device 4 is enhanced, the registration specific information and virtual specific information of the related cases registered in ST16 to ST18 are searched (ST23). Based on the above, search data generation unit 65 generates search data (ST24).

  On the other hand, when it is determined that the medical image display device 4 does not support enhanced image data, the registered specific information other than the enhanced image of the related case registered in ST16 to ST18 and the virtual specific information are searched ( ST25) Search data is generated based on these (ST24). At this time, in the search data based on the virtual specific information, search data that can be individually specified for each frame of the image of the enhanced image data D2 is created by virtual information such as a virtual UID.

  The generated search data is transmitted to the medical image display device 4 (ST26). The search data is, for example, an image list (including a patient list and an examination list) displayed on the medical image display device 4 and is displayed on the medical image display device 4. The user can specify a desired image from the image list displayed on the medical image display device 4 by a selection operation and make a provision request (display request).

  Next, processing of the medical image storage device 5 from receiving the designation of the request image from the medical image display device 4 to transmitting display data will be described with reference to FIG.

  For example, when the user performs a designation input operation for the requested frame with reference to the image list that is the search data transmitted to the medical image display device 4 in ST26, the image display request for the designated image is received in the receiving unit 51. When (request signal) is received (ST31), the designated image determination unit 66 determines whether the provided image data is the data to be singulated (ST32).

  Here, the data to be singulated includes enhanced image data that is designated for each frame and each image. That is, enhanced image data required as single frame image data is applicable. For example, the enhanced image data D2 is designated for each frame based on the search data created from the virtual specific information, or includes a case where sorting for each frame is required.

  If it is determined that the data is to be unified, the enhanced image data corresponding to the designated image is read (ST33), and the single image data generation unit 67 performs the unification process (ST34). Here, based on the specified virtual UID and virtual path, the single frame image data of the target frame is extracted from the virtual specific information of the corresponding stored enhanced image data and reconstructed to generate a single frame virtual image To do.

  On the other hand, when specific information that is not to be singulated is designated, the image data (single frame image data or multiframe image data) of the designated image is acquired from the image data storage unit 54 (ST35).

  Next, predetermined supplementary information is added based on the supplementary information J1 and J2 of the image data acquired in ST33 and ST35, and display data provided to the user is generated (ST36). At this time, the same or related supplementary information is added to the single frame image data generated by the single processing based on the supplementary information with respect to the original multiframe image data.

  This display data is transmitted to the medical image display device 4 by the transmission unit 55 (step SST37), and the process is terminated. As a result, the target medical image is displayed on the medical image display device 4.

  Next, processing by a transmission request other than designation based on search data will be described with reference to FIG.

  When the receiving unit 51 receives an image display request (request signal) for the designated image in response to a transmission request or the like of the medical image storage device 5 itself (step ST41), a transmission destination (providing destination) is selected and determined based on the transmission target. (ST42). Further, it is determined whether or not the image data designated as a transmission (provided) target is enhanced image data (ST43).

  If the designated image data is enhanced image data, the destination determination unit 64 determines whether the destination (providing destination) device is enhanced based on the corresponding image type information of the connected device as the destination. It is determined whether or not (step S44).

  When the providing destination is a model that supports enhancement, the registered image data to be requested is retrieved and acquired from the image data storage unit 54 (ST45), and transmission data for the user is obtained based on the incidental information of the specified image data. The transmission data is created (step ST46), and the transmission data is transmitted to the medical image display device 4 by the transmission unit 55 (ST47). As a result, the designated medical image is displayed on the medical image display device 4.

  On the other hand, when it is determined that the target image data transmitted in ST42 is not enhanced image data, the request target image data is acquired from the image data storage unit 54 (ST45), and the specified image data is determined. Based on the incidental information, transmission data for the user is created (step ST46), and the transmission data is transmitted to the medical image display device 4 by the transmission unit 55 (ST47). As a result, the designated medical image is displayed on the medical image display device 4.

  On the other hand, if the device to be provided is a non-enhancement model, the target specific information and image data are read (ST49) and the unification process is performed (ST50), as in ST33 and ST34. Next, transmission data is generated based on single frame image data as a virtual image obtained by the single processing (ST46), and the transmission data is transmitted to the medical image display device 4 by the transmission unit 55 (ST47). As a result, the designated medical image is displayed on the medical image display device 4.

  In the medical image archiving apparatus 5 according to the present embodiment, among the processing procedures described above, the image data registered in ST11 to ST18 is registered, and then the processing of ST21 to ST26, the processing of ST31 to ST37, and ST41 to ST47 are performed. These processes can be performed selectively or in combination. Any of these processing procedures can be omitted. For example, it is possible to selectively perform the processing of ST31 to ST37 and the processing of ST41 to ST47 according to the transmission request.

  According to the present embodiment, the following effects can be obtained. That is, by generating a search data by issuing a virtual DICOM image UID to each frame image of the enhanced image data, it can be handled as a single frame image from the other party, and is searched and specified for each frame. In addition, it is possible to acquire target image data for each frame.

  For example, when the target image data is behind a plurality of frames of enhanced image data having a very large data size, the target frame is designated by referring to the virtual search data by the above process, It is possible to acquire and display a target image in time.

  In addition, when it is desired to display enhanced image data composed of a plurality of frames connected in a fixed order, sorted in a different order from the frame order, the plurality of frames are displayed in a desired order with reference to virtual search data. By selecting and specifying these frames, it is possible to sort and display in a different order from the frame order.

  In this case, the user determines the display order from the information obtained from the search data such as the virtual image list displayed on the medical image display device 4 and the like and the rearrangement condition, and the single frame image from the storage device in the determined order. Can be acquired and displayed. Even in this case, since the enhanced image data can be handled for each frame, it is possible to obtain and display in the specified frame order earlier than obtaining all the enhanced image data, thereby reducing the initial display time. Can do. Further, since the next virtual image to be displayed can be acquired during the display, it is possible to perform streaming reproduction in an arbitrary display order using standard data acquisition means.

  As described above, in various usage situations, it is possible to reduce unnecessary time for downloading large-capacity data and shorten the time required for display.

  It is possible to refer to enhanced image data even in a display device that does not support enhanced image data.

  In this embodiment, since the single image is not stored in the storage device, but only the image data that needs to be provided as a single image is integrated, there is no need to increase the data storage area of the storage device.

  Since the conversion from the enhanced image data to the single frame image data is performed on the storage device side, the display device does not require a large work area even if the data size is very large.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.

  As an image display request, in addition to a display request based on a selection operation of a desired image from search data such as an image list (including a patient list and an examination list) displayed on the medical image display device 4, a medical report is created. Display request based on link information for starting image display function for reading out single frame image data included in diagnostic finding report created by support device 3 from image data storage unit 54, and pasting to diagnostic finding report for reference Any display request such as a display request based on an operation for starting the image display function by the image display function start information including the location information of the displayed image is included.

  Although the case where image data is provided and displayed on the medical image display device 4 has been described, the present invention is not limited thereto, and the present invention can be similarly applied to a case where the image data is displayed on the display unit 56 of the main body. In this case, the display unit 56 is a partner and a provider. Furthermore, the search data provider and the display data provider may be different devices.

  If the image display device 4 can handle an enhanced image, it may be possible to refer directly to the performance request.

Furthermore, when implementing this invention, you may combine the some component of the said embodiment suitably. In addition, some constituent elements may be deleted from all the constituent elements shown in the embodiments, and constituent elements over different embodiments may be appropriately combined.
