Description

  The present invention relates to a medical image diagnostic apparatus and an imaging preparation method, and more particularly to improvement in operability of the medical image diagnostic apparatus.

  In an examination using a medical image diagnostic apparatus, it is necessary to input information on a subject to be imaged and set imaging conditions before imaging is started. Specifically, the operator registers basic subject information such as the subject name, subject number, date of birth, etc. and the examination site in the medical image diagnostic apparatus. These pieces of information can be registered in advance as inspection reservation information in an inspection reservation system or the like.

  When the examination reservation information is registered in advance, the operator selects and inputs the subject corresponding to the examination day, so that the subject information is registered in the medical image diagnostic apparatus and displayed on the screen. Then, after confirming the display contents, the operator performs a click operation for changing the screen and continuously displays the shooting condition setting screen.

  At this time, the imaging protocol (imaging condition) of the examination registered in association with the subject information is read and displayed in each item of the imaging condition setting screen. Then, the operator confirms the display contents of the shooting condition setting screen, confirms the conditions by a click operation or the like, and then shifts to preparation for shooting. When the preparation for shooting is completed, the operator starts shooting by operating the shooting start button or the like.

  By the way, in a group examination such as a medical examination, a plurality of examinations may be performed under the same imaging conditions.

  Also in this case, as described above, the operator needs to set the subject information and the imaging conditions in the medical image diagnostic apparatus every time. Therefore, the operator has to repeat the same operation every time shooting is performed.

  Further, after completion of the examination, it is necessary to perform an operation for displaying a registration screen in order to register the subject information of the next subject. On the other hand, Patent Document 1 proposes a medical image diagnostic apparatus that automatically transitions to a registration screen for the next subject that has been reserved in advance after completion of the examination. As a result, the burden on the operator is reduced and the throughput of the entire photographing is improved.

  The examination reservation system 115 is a server device that manages information related to examination reservations and examinations such as a hospital information management system (HIS) and a radiation department information management system (RIS). The examination reservation system 115 stores examination reservation information of one or a plurality of medical image diagnostic apparatuses 1, examination information that is information on subject information, examination contents, imaging conditions for various examinations, and the like in a predetermined storage area (such as a database). Storage device).

  The image database 111 stores and stores image data captured by the medical image capturing device 112. In the example of FIG. 1, the image database 111 is configured to be connected to the operating device 100 via the network 110, but the image database 111 may be provided in, for example, the storage device 103 in the operating device 100.

  The CPU 101 of the operation device 100 calls a program stored in the main memory 102 or the storage device 103 to the work memory area on the RAM of the main memory 102 and executes it, and drives and controls each unit connected via the bus 113. Various processes performed by the controller device 100 are realized.

  In photographing a medical image using the medical image photographing device 112, the CPU 101 executes photographing preparation processing according to the procedure shown in FIG. Details of this photographing preparation process will be described later.

  The main memory 102 includes a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. The ROM permanently stores programs such as computer boot programs and BIOS, and data. The RAM temporarily holds programs, data, and the like loaded from the ROM, the storage device 103, and the like, and includes a work area that the CPU 101 uses for performing various processes.

  The storage device 103 is a storage device that reads / writes data to / from an HDD (hard disk drive) or other recording medium, and stores programs executed by the CPU 101, data necessary for program execution, an OS (operating system), and the like. . As for the program, a control program corresponding to the OS and an application program are stored.

For example, a pointing device such as a mouse 108 or a stylus pen is connected via the I / F 106. The pointing device outputs operation information such as designated position information, movement amount, movement direction, and mouse button to the CPU 101.

  The display memory 105 is a buffer that temporarily accumulates display data input from the CPU 101. The accumulated display data is output to the display device 107 at a predetermined timing.

  The display device 107 includes a display device such as a liquid crystal panel and a CRT monitor, and a logic circuit for executing display processing in cooperation with the display device, and is connected to the CPU 101 via the display memory 105. The display device 107 displays the display data stored in the display memory 105 under the control of the CPU 101.

  The input device 109 is an input device such as a keyboard, for example, and outputs various instructions and information input by the operator to the CPU 101. The operator interactively operates the operation device 100 using a pointing device such as the display device 107, the input device 109, and the mouse 108.

  The data reading device 114 is a data reading device that reads data from a recording medium such as a barcode reader or a card reader. The data reading device 114 reads, for example, bar code information and card information of an examination ticket and inputs them to the CPU 101. It is assumed that subject identification information such as at least an examination ticket number and a patient ID is recorded in the barcode information and card information.

  Next, the flow of imaging preparation processing executed by the controller device 100 according to the first embodiment will be described with reference to the flowchart of FIG.

  When the controller device 100 is activated, the CPU 101 of the controller device 100 reads and executes the automatic screen transition control task from the main memory 102 or the storage device 103 (step S101). In step S101, the CPU 101 reads setting information for automatic screen transition from the main memory 102 or the storage device 103. In the setting information, a value set by default or a value set by the operator using the automatic transition setting screen 30 (see FIG. 3) or the like is recorded.

  FIG. 3 is a diagram illustrating an example of the automatic transition setting screen 30.

  As shown in FIG. 3, the automatic transition setting screen 30 includes a mode selection field 30a for selecting whether the automatic transition mode of the screen is ON or OFF, and an information registration screen for displaying subject information and examination information Input field 30b for setting the display time of 31 (waiting time until transition to the next screen) and the display time of the shooting condition setting screen 32 (waiting time until shifting to shooting preparation) An input field 30c is provided.

  In the input fields 30b and 30c, a plurality of display time candidates may be displayed in a pull-down list, or any value may be input. When the display time of the information registration screen 31 and the display time of the shooting condition setting screen 32 are set for the input fields 30b and 30c, respectively, and the “save” button 30e is pressed by the mouse 108 or the like, the CPU 101 inputs the value Are stored in a predetermined storage location of the storage device 103 as setting information for automatic screen transition. When the “Cancel” button 30d is pressed by the mouse 108 or the like, the automatic transition setting screen 30 is closed and the processing returns to the original processing.

  The automatic screen transition setting information may be set to a different value for each operator. In that case, when reading the setting information in step S101, the CPU 101 acquires the setting information of the corresponding operator from the storage device 103 based on the identification information of the logged-in operator.

  Next, the CPU 101 determines ON / OFF of the automatic screen transition mode based on the setting information read in step S101 (step S102). If the automatic screen transition mode is OFF (step S102; OFF), the automatic screen transition control task is terminated as it is, and the routine proceeds to normal processing (manual screen transition processing).

  When the automatic screen transition mode is ON (step S102; ON), the CPU 101 performs registration and setting of information necessary for shooting preparation and processing up to the start of shooting preparation without an operator's operation. Therefore, first, the CPU 101 acquires subject information and examination information (step S103).

  The patient information may be input by the operator using the input device 109 or the like, but the data reader 114 stores the barcode of the examination ticket or the like, the examination ticket number recorded on the IC card and the subject identification information. It is desirable that the CPU 101 obtains corresponding subject information from the examination reservation system 115 or the like. The CPU 101 reads information (subject number, reception number, subject name, date of birth, gender, etc.) necessary for preparation for imaging from the subject information from the examination reservation system 115 and the like. Further, the CPU 101 reads examination information (examination site, imaging conditions, imaging instructions, etc.) registered in association with the subject information from the above-described examination reservation system 115 and the like.

  If the subject information or examination information is not registered in the examination reservation system 115 or if correction is required, the operator confirms the examination form and uses the input device 109 based on the doctor's instructions. Will be entered. In this case, the automatic screen transition mode is turned off.

  The CPU 101 reflects and displays the subject information and the examination information acquired in step S103 on the information registration screen 31. The CPU 101 measures the display time as the information registration screen 31 is displayed (step S104).

  FIG. 4A shows an example of the information registration screen 31. FIG. As shown in FIG. 4 (a), the information registration screen 31 is provided with a subject information input area 31a and an examination information input area 31b. By the process of step S104, the subject information acquired in step S103 is reflected and displayed in the subject information input area 31a, and the examination information acquired in step S103 is reflected and displayed in the examination information input area 31b.

  The CPU 101 waits until the remaining display time (standby time) of the information registration screen 31 becomes “0” (step S105; No). If the subject information input area 31a or the examination information input area 31b is clicked with the mouse 108 or the like before the remaining display time (standby time) of the information registration screen 31 becomes “0”, the CPU 101 The transition mode is turned OFF, and correction or input of data in the subject information input area 31a or the examination information input area 31b is accepted.

  In this case, the CPU 101 displays a “registration complete” button 31c. The “registration complete” button 31c is operated by the operator when data correction or additional input is completed. When the “registration complete” button 31c is pressed, the screen is forcibly shifted to the next screen (imaging condition setting screen 32).

  When the remaining display time of the information registration screen 31 becomes “0” (step S105; Yes), the CPU 101 reads out the imaging protocol (imaging conditions) corresponding to the examination information (step S106) and reflects it on the information registration screen 31 for display. To do. The CPU 101 measures the display time as the display starts (step S107).

  FIG. 4B is an example of the shooting condition setting screen 32. As shown in FIG. 4 (b), the shooting condition setting screen 32 is provided with a shooting condition setting area 32a for displaying the value of each parameter of the shooting conditions, image display fields 32b, 32c, 32d, and the like. As a result of the processing in step S107, the photographing condition acquired in step S106 is reflected and displayed in the photographing condition setting area 32a. In the image display fields 32b, 32c, and 32d, information such as a past image and an image showing the body position of the subject, a shooting direction, and the like are displayed.

  The CPU 101 waits until the remaining display time (standby time) of the shooting condition setting screen 32 becomes “0” (step S108; No). If the shooting condition setting area 32a is clicked with the mouse 108 or the like before the remaining display time (standby time) becomes “0”, the CPU 101 turns off the automatic screen transition mode and the data in the shooting condition setting area 32a. Accepts corrections and additional input. In this case, the CPU 101 displays a “shooting preparation” button (not shown) in the shooting condition setting screen 32. The “shooting preparation” button is operated by the operator when data correction or additional input is completed. When the “shooting preparation” button is pressed, the process forcibly shifts to the next process (shooting preparation).

  When the remaining display time of the shooting condition setting screen 32 becomes “0” (step S108; Yes), the CPU 101 executes shooting preparation processing (step S109). In the imaging preparation process, the CPU 101 controls each unit of the medical image imaging apparatus 112 to perform standby of the X-ray apparatus, rotation of the scan gantry (rotary disk), alignment of the bed, and the like. When the preparation for photographing of the medical image photographing device 112 is completed, the CPU 101 displays the `` start photographing '' button 32e on the display screen of the operation device 100, or blinks the `` START '' button (not shown) provided on the operation device 100, Make the shooting start operation effective. Thereafter, in order to start shooting, it is necessary to manually perform an operation to instruct the start of shooting. When the “shooting start” button 32e or the “START” button is pressed by the operator's operation (step S110), the CPU 101 transmits a shooting start instruction to the medical image shooting apparatus 112 and starts shooting (step S111).

  As described above, the operating device 100 of the medical image diagnostic apparatus 1 according to the present invention acquires information such as subject information, examination information, and imaging conditions suitable for examination as information necessary for imaging preparation. The acquired information is sequentially displayed as a predetermined standby time elapses in a plurality of stages as in the information registration screen 31 in FIG. 4 (a) and the shooting condition setting screen 32 in FIG. 4 (b). In addition, since it is necessary to manually issue a shooting start instruction, an operation unit such as a “shooting start” button 32e is provided.

  When the “shooting start” button 32e is operated by the operator, the CPU 101 controls to start shooting using this as a trigger. As a result, even if the operator does not perform an operation, information necessary for shooting is sequentially displayed at a predetermined timing. Therefore, when performing many tests such as group tests where the examination items and the subjects to be examined in advance are determined, the operator manually registers the patient information, sets the imaging conditions, and prepares the imaging manually each time. It does not have to be done. As a result, the work load on the operator is reduced, and the overall inspection throughput can be improved.

  In addition, after the shooting condition setting screen 32 is displayed, if the display of the shooting start button 32e is enabled after a predetermined waiting time has elapsed and the operation is enabled, the operator must wait for confirmation of the shooting conditions. Therefore, the medical image diagnostic apparatus 1 can be handled safely.

  In addition, since it is possible to set or change the standby time for screen transition using a predetermined user interface, such as the automatic transition setting screen 30 in FIG. 3, it is possible to freely set an appropriate timing for the operator. The screen can be changed. In addition, if the waiting time for screen transition can be set for each operator, it becomes more convenient for each operator.

  In addition, subject information is acquired using a data reader 114 such as a card reader or a barcode reader, and detailed information and examination information of the subject subject, examination protocol, etc. are obtained from the examination reservation system 115 etc. By doing so, information necessary for shooting can be acquired and shooting conditions can be set without the operator performing any keyboard input operation or mouse 108 click operation. The procedure up to the preparation for shooting can be made extremely simple and smooth.

  In the above processing example, the information necessary for shooting is displayed in two stages of the information registration screen 31 and the shooting condition setting screen 32. However, the present invention is not limited to this, and the three stages are displayed. It is good also as what is divided and displayed sequentially. In addition, the layout and display contents of each screen are examples, and can be changed as appropriate.

[Second Embodiment]
Next, a second embodiment of the present invention will be described.

  In the second embodiment, in the medical image diagnostic apparatus 1 of the first embodiment, the standby time can be adjusted by an operator's operation during the elapse of a predetermined standby time until the screen transition. Therefore, the CPU 101 may add the time adjustment process shown in FIG. 5 during the standby time of steps S104 to S105 and steps S107 to S108 shown in FIG.

  When the mouse 108 is operated by the operator while the information registration screen 31, the shooting condition setting screen 32, or the like is being displayed, that is, during the elapse of the waiting time until the screen transition (step S201), as in the procedure shown in FIG. (Step S202), the CPU 101 acquires the movement information of the mouse 108 and executes control associated with the direction of movement. The left-right movement of the mouse 108 (step S202; left-right movement) is to return or advance the elapsed time.

  Specifically, as shown in FIG. 6, when the mouse 108 is moved to the left, the CPU 101 returns the elapsed time, and when the mouse 108 is moved to the right, the CPU 101 advances the elapsed time ( Step S203). For example, when the mouse 108 is moved up and down (step S202; up and down movement), the CPU 101 adjusts the elapsed speed of time. Specifically, as shown in FIG. 6, when the mouse 108 is moved up, the CPU 101 increases the elapsed speed of time faster than the current speed, and when it is moved down, the CPU 101 elapses of time. The speed is made slower than the current speed (step S204).

  The time adjustment processing in FIG. 5 may be performed any number of times until the remaining time (standby time) of the screen display becomes “0” (step S105 in FIG. 2; No → step S202 to step S204 in FIG. 5). ). After that, when the remaining screen display time (standby time) becomes “0” (step S205; Yes), the CPU 101 ends the time adjustment process and transitions to the next screen. Alternatively, the process proceeds to shooting preparation processing.

  The setting for associating the operation of the mouse 108 with the control content can be set in advance on a predetermined setting screen. When the elapsed speed or the like is adjusted by the time adjustment process, the CPU 101 holds the adjustment value immediately before the screen transition in the main memory 102 for each screen. Then, after a series of shooting preparation processes (steps S101 to S111 in FIG. 2), the adjustment values stored in the main memory 102 may be stored in a predetermined storage location for recording screen transition setting information. . Thereby, even when performing the imaging preparation process for the next subject, it is possible to automatically change the screen using the previously adjusted value.

  As described above, according to the medical image diagnostic apparatus 1 of the second embodiment, by performing a predetermined operation with the mouse when automatically transitioning from the information registration screen 31 to the imaging condition setting screen 32, It is possible to adjust the time until the transition to the next screen and the elapsed time speed during screen display. If the operator takes more time than usual to check the patient information or examination information, or if it takes time to check the shooting conditions after transition to the shooting condition setting screen, the screen can be changed freely by the operator's operation. Time can be extended, thereby preventing problems such as the operator moving to the next screen without confirmation. Further, after confirming the contents of the screen, if the operator operates it, it is possible to proceed to the next screen without waiting for the subsequent waiting time, which improves usability.

[Third embodiment]
When the subject is a child or an elderly person, the setting of the subject may take time, and it may take time to verify the identity. Considering this, in the first or second medical image diagnostic apparatus 1, the CPU 101 may determine the waiting time until the screen transition according to the age of the subject.

  The CPU 101 acquires the age of the subject from the subject information, and determines the transition time from the information registration screen 31 to the imaging condition setting screen 32 for each age. For example, a check box for setting the screen transition time for each age is added to the automatic transition setting screen 30 shown in FIG. The set screen transition standby times are grouped by age or age, and are stored in a predetermined file for recording setting information.

  The CPU 101 obtains the age of the subject from the subject information when the information registration screen 31 is displayed, obtains the screen transition standby time corresponding to the age from the above file, and displays the screen based on the acquired screen transition standby time. Controls the display and transition to the next screen. The age may be divided into several groups such as under 10s, 10-50s, 60s, 70s, 80s or more, and each age group may be associated with a waiting time.

[Fourth embodiment]
In the first to third medical image diagnostic apparatuses 1, the CPU 101 may set the waiting time until screen transition based on the amount of information displayed on each screen and the importance. For example, since the information registration screen 31 includes subject information and examination information, the number of items displayed is large. In this case, since confirmation takes time, the screen transition standby time is set longer.

  Further, since the number of characters and the importance of each item are different, the time required for the operator to check is different for each item. Therefore, the CPU 101 may calculate the waiting time until the screen transition according to the number of characters and the importance of the item.

  For example, if 10 characters require 2 seconds of confirmation time, there are 10 items to be confirmed, and if 3 items are 10 characters or more and 20 characters or less, the confirmation time required for those 3 items is Calculate as basic time 2 seconds x 1.5. In this case, the display time is (7 items × 2 seconds) + (3 items × (2 seconds × 1.5)) = 23 seconds.

  Note that the above basic time may not be the same time for all items, but may be a time according to the importance of the items. For example, for items with high importance, the basic time is set longer than the standard basic time. In this way, the waiting time until screen transition is calculated and set based on the amount of information such as the number of items and the number of characters and the importance. As a result, the screen can be changed at a more preferable timing.

[Fifth embodiment]
In the first to fourth embodiments, it is desirable that the waiting time until the screen transition is optimized by learning processing by the CPU 101. For this reason, in the medical image diagnostic apparatus 1 of the fifth embodiment, in addition to the configuration of the medical image diagnostic apparatus 1 of the first embodiment, a GUI for forcibly inputting an operation for moving to the next screen (Screen switching button) etc. are provided. The CPU 101 measures the time until the operator forcibly transitions to the next screen by operating the screen switching button, and records it as the learning data 4 in the storage device 103 or the main memory 102. The learning data 4 is preferably recorded for each screen and for each user.

  As shown in FIG. 7, in the learning data 4, the inspection date, information registration screen display time, imaging condition setting screen display time, operator user ID, and the like are recorded for each inspection. Note that these items are the minimum items necessary for learning, and the age and examination site of the subject may be recorded in the learning data 4.

  Specifically, the CPU 101 measures the time from when the information registration screen 31 shown in FIG. 4 (a) is displayed until the registration completion button 31c is clicked. Record in item. The CPU 101 measures the time from when the shooting condition setting screen 32 shown in FIG. 4 (b) is displayed until the shooting preparation button (not shown) is clicked. In the item.

  The CPU 101 aggregates the data for a certain period recorded in the learning data 4 at user ID units or all ID data at a predetermined timing such as when the medical image diagnostic apparatus 1 is shut down. The registration screen display time and the shooting condition setting screen display time are obtained. For example, the average display time of each screen may be set as an appropriate display time. The CPU 101 updates and records the obtained appropriate information registration screen display time and shooting condition setting screen display time as standby time setting information. In the next examination, using the updated waiting time setting information, the imaging preparation process (see FIG. 2) is performed as in the first embodiment.

  In order to cause the controller device 100 to execute the learning process, for example, an item for ON / OFF setting of the learning mode may be added to the automatic transition setting screen 30 shown in FIG. When the learning mode is set to ON, the CPU 101 collects learning data 4 every time an inspection is performed. Further, when the learning mode is set to OFF, the CPU 101 changes the screen using the standby time obtained using the learning data 4. Alternatively, as in the first embodiment, it is possible to select whether to use the standby time set on the automatic transition setting screen (FIG. 3) or the standby time obtained using the learning data 4 Good. The CPU 101 changes the screen using the waiting time selected by the operator.

  As described above, in the fifth embodiment, a learning function is added, and an appropriate waiting time is calculated from learning data 4 obtained by measuring the time until the operator changes the screen for each examination. As a result, the screen can be changed at an optimal timing. If learning processing is performed for each operator in use, screen transition can be performed at a comfortable timing even when the confirmation speed of the screen is different for each operator.

[Sixth embodiment]
The medical image diagnostic apparatus 1 of the sixth embodiment further has a function of notifying the operator of the timing of screen transition in the medical image diagnostic apparatus 1 of the first to fifth embodiments.

  FIG. 8 is an example of the information registration screen 35 according to the sixth embodiment. As shown in FIG. 8, the information registration screen 35 includes information on the subject such as the subject number 35a, the reception number 35b, the subject name 35c, the date of birth 35d, the sex 35e, the age 35f, and the examination site. Information on examinations such as 35g, imaging protocol 35h, and body position 35i are displayed.

  While displaying the subject information 35a to 35f and the examination information 35g to 35i, the CPU 101 notifies how long the screen will change before the screen is changed. As a notification method, for example, it is desirable to display progress bars 36a and 36b as shown in FIG. In the example of FIG. 8, each input field (display column) of the item to be confirmed is a progress bar 36a, 36b indicating the passage of time. The items to be confirmed may be all items (input fields 35a to 35i) or some items. The selection of items to be confirmed may be set by the operator.

  The CPU 101 indicates the progress by sequentially filling the display column (input field) of the items to be confirmed over time. When all the display columns (input fields) for all items to be confirmed are completely filled, the process proceeds to the next shooting condition setting screen 32.

  Thus, by displaying the progress bars 36a and 36b indicating the passage of the standby time in each item, the operator can predict the time until the screen transition. In addition, when it is determined that the confirmation time is insufficient or too long, the waiting time can be adjusted by performing the time adjustment processing shown in the second embodiment.

  As another elapsed time display example, as shown in FIG. 9, a progress bar 37a may be displayed at the bottom (or top) of the screen, or the remaining time until screen transition may be displayed on the screen. In addition to the visual notification method as shown in FIGS. 8 and 9, an audio notification method may be combined. In an auditory notification method, the CPU 101 sounds a notification sound once, for example, 10 seconds before the screen transitions. Furthermore, when 5 seconds ago, the notification sound is generated twice. Alternatively, the remaining time may be notified by voice guidance.

  As described above, by providing the function of notifying the time until the screen transitions, the operator can visually or audibly know how long the screen will change. You can check the information with confidence because you know the approximate remaining time.

[Seventh embodiment]
In the first to sixth embodiments, the standby time for screen transition may be adjusted so as to be interlocked with the operation on the medical image photographing apparatus 112 (scanner gantry or the like) side. In general, in the flow of examination using the medical image diagnostic apparatus 1, the operator first confirms the subject information, and then guides the subject to the examination room. Therefore, the operator confirms the name of the subject, etc., and confirms that the subject information matches the subject information displayed on the screen, and sets and aligns the subject on the bed. . After the alignment is completed, the operator returns to the operation room, and next confirms the shooting conditions on the shooting condition setting screen displayed on the controller device 100, and then performs shooting.

  In such a work flow, it is a time loss from the completion of the setting of the subject until the operator returns to the operation room and the transition to the next screen. Therefore, in the seventh embodiment, when the setting of the subject is completed using the operation button of the scanner gantry (medical image capturing device 112) while the operator is in the examination room, the medical image capturing device 112 While preparing for photographing such as standby of the scanner, the CPU 101 may forcibly shift to the photographing condition setting screen 32 on the operation device 100 side by using this setting completion operation as a trigger.

  Thereby, even if the waiting time for screen transition does not elapse, when the operator returns to the operation room, the photographing condition setting screen 32 is switched to the operation device 100 with good timing, so that the subsequent work proceeds smoothly. On the other hand, when the waiting time of the information registration screen 31 elapses during the setting of the subject, the CPU 101 controls to extend the waiting time and to change the screen after the setting completion operation.

  With reference to the flowchart of FIG. 10, a flow of imaging preparation processing executed by the controller device 100 in the seventh embodiment will be described.

  Steps S301 to S304 in the flowchart of FIG. 10 are the same as steps S101 to S104 in the first embodiment. That is, when the controller device 100 is activated, the CPU 101 of the controller device 100 reads and executes an automatic screen transition control task from the main memory 102 or the storage device 103 (step S301). If the automatic screen transition mode is OFF (step S302; OFF), the automatic screen transition control task is terminated as it is, and the processing shifts to normal processing (processing for manually changing the screen and setting shooting conditions).

  When the automatic screen transition mode is ON (step S302; ON), the CPU 101 acquires subject information and examination information (step S303). The subject information is acquired, for example, when the data reader 114 reads barcode information, card information, or the like recorded on an examination ticket or the like. Further, the CPU 101 reads all the subject information and examination information linked to the inputted subject information from the examination reservation system 115 and the like.

  The CPU 101 registers the subject information and the examination information acquired in step S103 and reflects them on the information registration screen 31 for display. Along with the start of display, the display time is measured (step S304). The information registration screen 31 is also displayed on a display provided on the medical image photographing apparatus 112 (scan gantry) side.

  Here, the operator moves to the examination room and guides the subject to the bed while checking whether the subject information displayed on the medical imaging apparatus 112 side matches the subject, and aligns the subject. To do. The alignment is performed by an operation button provided on the medical image photographing apparatus 112.

  When the alignment is completed and the subject setting completion button is pressed (step S305; Yes), the CPU 101 of the controller device 100 reads out the imaging conditions without waiting for the screen transition waiting time to elapse, and the imaging conditions The setting screen 32 is displayed (step S308).

  When the alignment is not completed, that is, the subject setting completion button is not pressed (step S305; No), when the standby time elapses (step S306; Yes), the CPU 101 of the controller device 100 sets the standby time to a predetermined time. (Step S307) and return to step S305.

  Thereafter, when the subject setting completion operation is performed (step S305; Yes), the process proceeds to step S308, the imaging conditions are read, and the imaging condition setting screen 32 is displayed. The CPU 101 measures the display time at the start of display (steps S308 and S309). When the operator finishes positioning of the subject and returns to the examination room, the imaging condition setting screen 32 is displayed on the display device 107 of the operating device 100.

  Thereafter, the operator confirms the contents while the shooting condition setting screen 32 is displayed. The CPU counts down the predetermined waiting time, and when the remaining display time becomes “0” (step S310; Yes), it executes a shooting preparation process (step S311). When the preparation for shooting is completed, the CPU 101 displays a “shooting start” button 32e so that the shooting start operation becomes valid. Thereafter, in order to start shooting, it is necessary to manually perform an operation to instruct the start of shooting, such as pressing the “shooting start” button 32e by the operator. When the shooting start operation is manually performed (step S312), the CPU 101 starts shooting processing (step S313).

  As described above, the medical image diagnostic apparatus 1 of the present invention performs screen transition without waiting for the standby time or automatically extends the standby time in conjunction with the operation on the medical image photographing apparatus 112 side. Also good. Accordingly, the screen can be changed according to the work flow of the operator who is preparing for photographing, and the inspection can be smoothly advanced.
