Description

  The present invention relates to a medical image diagnostic apparatus such as an X-ray CT apparatus, an MRI apparatus, an ultrasonic diagnostic apparatus, a nuclear medicine diagnostic apparatus, or an X-ray diagnostic apparatus, and more particularly to a medical image diagnostic apparatus that executes predetermined processing according to an examination plan. .

  In a medical image diagnostic apparatus such as an X-ray CT apparatus, an examination plan including a plurality of processing procedures and processing conditions are input to the medical image diagnostic apparatus every time an examination is performed.

Here, the inspection plan and imaging conditions will be described. The inspection plan is information indicating a series of processing steps executed in the inspection. As a specific example, an example of an inspection plan for inspection by an X-ray CT apparatus is shown below.
Examples of inspection plans: (1) Scanogram imaging, (2) Determination of scan position using scanogram, (3) Setting of bed position, (4) Execution of scan, (5) Image data collected by scan Transfer to an external storage medium, (6) Capture the collected image data on X-ray film.
The processing contents of (1) to (6) become an inspection plan, and according to an example of this inspection plan, the processing of (1) to (6) is executed in order.

  The processing conditions included in the inspection plan include, for example, imaging conditions (imaging parameters), imaging method, contents of image processing after imaging, transfer destination of collected image data, storage destination of image data, and the like. Can be mentioned. The imaging conditions of the X-ray CT apparatus include, for example, the current value of the X-ray tube, the imaging pitch, the reconstruction pitch, the FOV size, and the like.

  The content of the image processing includes general image processing performed on medical image data, and corresponds to volume rendering processing, MPR processing (Multi Planar Reconstruction), and the like, for example.

  In addition, when a network is constructed by RIS (radiological department information management system), HIS (hospital information system) and PACS (medical image storage communication system), and a medical image diagnostic apparatus is connected to the network, medical image diagnosis The image data collected by the apparatus is transferred to and stored in a PACS image server or the like. In this case, a PACS image server or the like is a transfer destination of image data. Further, an external recording medium such as a magnetic disk or an optical disk corresponds to the storage destination of the image data.

  In addition, the examination plan selected according to the patient's diseased part, symptoms, etc. and the processing conditions are stored in advance in the medical image diagnostic apparatus as an examination template, and the examination template is selected at the time of imaging. Is performed (for example, patent document 1).

Japanese Patent No. 3285533

  By the way, at the time of imaging, after an operator selects an examination template stored in advance in the medical image diagnostic apparatus, the examination plan, imaging conditions, and image processing included in the examination template are included in order to match the patient, disease, etc. There are cases where the contents or the transfer destination of image data is changed (adjusted). For example, there may be a case where a part of an inspection plan is changed, an imaging condition is added, a part of image processing content is deleted, or an image data transfer destination is changed. In this way, the inspection plan and imaging conditions may be changed (adjusted), but the capacity of the storage device is limited and there is a problem in searchability, so the inspection plan and imaging conditions after the change, etc. Are generally not preserved. That is, there is a limit to the capacity of the storage device of the medical image diagnostic apparatus, and it is not possible to secure a capacity for storing the changed examination plan or imaging conditions. It was not done. Moreover, if all the inspection plans after the change are saved, a large amount of inspection plans and imaging conditions are stored in the storage device, so that it takes time to search for the desired inspection plan and imaging conditions. As described above, searchability of a desired inspection plan and the like deteriorates, so that the changed inspection plan and the like are not stored in the storage device.

  However, when comparing the state of the diagnostic site before surgery with the status of the diagnostic site after surgery, it is better to take images under the same conditions as the imaging conditions before and after surgery. Comparison is easy. In addition, when observing the progress of a diagnostic site, it is easier to compare the diagnostic sites if imaging is performed under the same imaging conditions at each time. However, when the imaging conditions included in the pre-stored examination template are changed and imaging is performed before surgery, the imaging conditions after the change are discarded without being stored in the storage device. In this case, the imaging conditions before the operation cannot be read from the storage device and used, and it is necessary to input the same conditions as the imaging conditions before the operation to the apparatus again. In this case, it is necessary to write down the shooting conditions before surgery in a memo or the like, or the operator needs to remember it, so it is not possible to easily set the same shooting conditions, which is a burden on the operator. It was.

  In order to solve this problem, an imaging condition or the like is also set by referring to the content of an inspection performed in the past. For example, when a medical image is collected using an X-ray CT apparatus, and an imaging condition is displayed together with a medical image on an X-ray film obtained in the past, the operator displays it on the past X-ray film. While viewing the imaging conditions, the imaging conditions for the examination to be performed from now on are input manually to the X-ray CT apparatus. On the X-ray film, imaging conditions such as an X-ray tube current value, imaging pitch, reconstruction pitch, and FOV size are displayed together with a medical image. The operator refers to the imaging conditions in the X-ray film and inputs the imaging conditions to be performed to the X-ray CT apparatus. However, since it is necessary to input the imaging conditions while referring to the X-ray film, the input is troublesome for the operator, and there is a risk of erroneous input. There was a need to enter.

  In addition, when multiple image data are collected by executing inspection, the number of generated image data, the name of the image data transfer destination device, the name of the image data storage destination recording device, etc. are not displayed on the display device. Therefore, the operator cannot easily check the number of image data, the transfer destination, or the storage destination. In addition, when executing a series of processes consisting of image collection, image processing, and storage of image data, it is not displayed on the display device how far the process has been completed, so the operator must check the work status. It was difficult. In particular, when dozens of examinations are carried out with the same medical image diagnostic apparatus, since the same apparatus is used instead of multiple radiographers, operations such as imaging and image processing are performed. If the transfer destination or the like is not displayed on the display device, there is a problem that it is difficult to grasp the progress of the examination that the person is in charge of and the progress of the image processing.

In addition, when the storage of the image data is not completed, the control unit 2 displays the check field 36a as an empty blank, and when the storage is completed, the control unit 2 colors the check field 36a in a predetermined color. Display.

  The formats of the display columns 30 to 36 are stored in advance in a storage device (not shown) connected to the control unit 2, and the control unit 2 reads out the formats of the display columns 30 to 36 from the storage device. The display columns 30 to 36 are displayed on the ten monitor screens 10a, and the images and photographing conditions acquired from the past examination data storage unit 6 are displayed in the corresponding display columns 30 to 36.

  In addition, the display column 41 of the examination information 40 to be executed includes a display column 42 to a display column 46. The display column 42 is a display column for displaying a scanogram indicating the shooting position. The display column 43 is a display column for displaying the imaging conditions of the examination to be performed from now. Since the imaging conditions are created in advance according to the disease and the diagnosis site and stored in the examination template file, the imaging conditions stored in the examination template file can be displayed by selecting the desired examination template file. 43. Similar to the imaging conditions in the past examination, the tube current, slice width, pitch and the like are included. Note that the shooting conditions can be changed to any value by the operator. The display column 44 is a display column for displaying an image scheduled to be collected from now on or an image scheduled to be generated by image processing. In the example shown in FIG. 3, the display field 44 includes a display field 44 a for displaying an image (axial image) scheduled to be captured and collected, and an image (coronal image) generated by image processing. ) And a display field 44c for displaying an image (three-dimensional image) scheduled to be generated by image processing. The control unit 2 displays the title “axial image” indicating the type of image in order to indicate the type of image displayed in the display column 44a above the display column 44a. In addition, the control unit 2 displays the title “coronal image” indicating the type of image in order to indicate the content of the image processing and the type of image displayed in the display column 34b above the display column 44b. The display of this “coronal image” represents the contents of the image processing. In addition, the control unit 2 displays the title “3D image” indicating the type of image in order to indicate the content of the image processing and the type of image displayed in the display column 44 c above the display column 34 c. . The display of this “three-dimensional image” represents the contents of the image processing. The display columns 44a, 44b, and 44c are each composed of a plurality of columns, and the display columns 44a, 44b, and 44c can display a plurality of images. The example of the coronal image is one example, and a sagittal image, an image of an arbitrary cross section, or the like may be displayed.

  The display field 44a for displaying an image (axial image) to be collected includes a check field 44d for displaying completion or incomplete of image collection, and a display for displaying a coronal image. The column 44b includes a check column 44e for displaying completion or incomplete of image generation, and the display column 44c for displaying a three-dimensional image also displays completion or incomplete of image generation. A check field 44f is included. For example, when the scan is not completed, the control unit 2 displays the check field 44d as a white blank, and when the scan is completed, the control unit 2 displays the check field 44d with a predetermined color, for example. Let Further, for example, when a predetermined number of coronal images are generated, if the planned number of image processing is not completed, the control unit 2 displays the check field 44e as a white blank, and the planned number of image processing is completed. In this case, the control unit 2 displays the check field 44e in a predetermined color, for example. In the check field 44f included in the display field 44c for displaying the three-dimensional image, when the image processing is not completed, the control unit 2 displays the check field 44f as an empty blank and the image processing is completed. In this case, the control unit 2 displays the check field 44f in a predetermined color, for example.

  The display column 45 is a display column for displaying the transfer destination of the image data, and the display column 46 is a display column for displaying the storage destination of the image data. The display field 45 for displaying the transfer destination includes a check field 45a for displaying the completion or incomplete of the transfer, and the display field 46 for displaying the storage destination is the completion or incomplete of the storage. Is included in the check field 46a. When the transfer of the image data is not completed, the control unit 2 displays the check field 45a as an empty blank field, and when the transfer is completed, the control unit 2 displays the check field with a predetermined color, for example. . In addition, when the storage of the image data is not completed, the control unit 2 displays the check field 46a as an empty blank, and when the storage is completed, the control unit 2 colors the check field 46a in a predetermined color, for example. To display.

  The format of the display columns 40 to 46 is stored in advance in a storage device (not shown) connected to the control unit 2, and the control unit 2 reads the format of the display columns 40 to 46 from the storage device, and displays the display device. The display fields 40 to 46 are displayed on the ten monitor screens 10a, the photographing conditions included in the examination template file are displayed in the display field 43, the transfer destination of the image data is displayed in the display field 45, and the image data is saved. The destination is displayed in the display column 46.

  And the control part 2 makes each part perform each process according to a test | inspection plan (step S06). For example, in the case of an inspection plan as shown in FIG. 4, the control unit 2 causes the imaging unit 14 to collect a scanogram (Process 1). The scanogram data collected by the imaging unit 14 is temporarily held in the image data storage unit 8, and the control unit 2 outputs the scanogram data to the display device 10 and displays the scanogram in the display field 42 on the monitor screen 10a. Let Next, the operator determines the scan position based on the scanogram (processing 2). When the scan position is determined, the control unit 2 causes the imaging unit 14 to collect image data in accordance with the imaging conditions included in the inspection template (processing 3).

  When the examination is executed in this way and the image data of the subject is collected, the collected image data is output from the imaging unit 14 to the image data storage unit 8 and temporarily held in the image data storage unit 8. The Then, the control unit 2 reads the image data from the image data storage unit 8, sequentially outputs the image data to the display device 10, and sequentially displays the images on the monitor screen 10 a of the display device 10. At this time, the controller 2 sequentially displays images within the frame of the display field 44a on the monitor screen 10a (step S07). For example, as illustrated in FIG. 5, the control unit 2 displays the collected images sequentially in individual fields in a display field 44 a including a plurality of fields. In FIG. 5, a state where the display column 44 a is white represents a state where no image is displayed, and a colored state represents a state where an image is displayed. In this way, by sequentially displaying the collected images on the display device 10, the operator can easily check the progress of image collection.

  When the scanning by the photographing unit 14 ends (step S08, Yes), the control unit 2 receives a signal indicating the end of scanning from the photographing unit 14, and the control unit 2 is displayed on the monitor screen 10a of the display device 10. The check field 44d is displayed in a predetermined color, for example (step S09). As a result, the operator can recognize that the collection of the image data has ended. Further, during the execution of the scan, the control unit 2 may cause the display device 10 to display that the scan is being executed. For example, the control unit 2 may separately display a display field for displaying the status state on the monitor screen 10a of the display device 10 and display a message such as “scanning in progress” in the display field.

  As shown in FIG. 4, when performing predetermined image processing (Process 4) according to the inspection plan, the control unit 2 uses the image data collected by the imaging unit 14 and stored in the image data storage unit 8 as image data. The data is output to the processing unit 16. When the image processing unit 16 receives the image data from the image data storage unit 8, the image processing unit 16 performs image processing according to the image processing content included in the selected inspection template file. The image processing unit 16 performs, for example, MPR processing, volume rendering processing, and the like to generate image data of an arbitrary cross section, three-dimensional image data, and the like, and outputs the generated image data to the image data storage unit 8. The image data is temporarily stored in the image data storage unit 8. The control unit 2 reads the image data generated by the image processing unit 16 from the image data storage unit 8, sequentially outputs the data to the display device 10, and sequentially displays the images on the monitor screen 10a of the display device 10. For example, when coronal image data and 3D image data are generated by the image processing unit 16, the control unit 2 sequentially outputs the coronal image data and 3D image data to the display device 10. And the control part 2 displays a coronal image and a three-dimensional image sequentially on the predetermined | prescribed display column of the monitor screen 10a of the display apparatus 10. FIG. In this case, the control unit 2 sequentially displays the coronal images in the display field 44b and sequentially displays the three-dimensional image in the table field 44c. For example, as illustrated in FIG. 6, the control unit 2 causes the generated coronal images to be sequentially displayed in the individual columns in the display column 44 b including a plurality of columns. In FIG. 6, a state where the display column 44 b is white represents a state where no image is displayed, and a colored state represents a state where an image is displayed. FIG. 6 shows an example in which a coronal image is displayed in the display column 44b, but a three-dimensional image is also sequentially displayed in the display column 44c in the same manner as the coronal image. Thus, by sequentially displaying the generated images on the display device 10, the operator can easily check the progress of the image processing.

  When the image processing by the image processing unit 16 ends, the control unit 2 receives a signal indicating the end of the image processing from the photographing unit 14, and the control unit 2 displays a check column displayed on the monitor screen 10a of the display device 10. Colored and displayed in a predetermined color. For example, when the image processing for generating the coronal image is completed, the control unit 2 displays the check field 44e in a predetermined color, and when the image processing for generating the three-dimensional image is completed, the control unit 2 Displays the check field 44f in a predetermined color. As a result, the operator can recognize that the image processing has been completed. Further, during the execution of the image processing, the control unit 2 may cause the display device 10 to display that the image processing is being executed.

  When transferring the collected image data or the image data generated by the image processing to an external image server or the like according to the inspection plan shown in FIG. 4 (processing 5), the control unit 2 stores the image data in the image data storage unit 8. The stored image data is read out and transferred to an external image server (not shown) connected to the network N via the communication unit 20. At this time, the control unit 2 transfers the image data to the image data transfer destination included in the selected inspection template file. For example, when the medical image diagnostic apparatus 1 is connected to a plurality of image servers, when the image server B is described as the image data transfer destination in the examination template file, the control unit 2 stores the image data in the image server B. Forward. In this case, the display field 45 displays the name (identifier) of the image server B. When the transfer of the image data ends, the control unit 2 displays the check field 45a of the display device 10 in a predetermined color. As a result, the operator can recognize that the transfer of the image data has been completed.

  Further, when the collected image data or the image data generated by the image processing is stored in an external recording medium 18 (for example, a hard disk or an optical disk) according to the inspection plan (processing 6), the control unit 2 stores the image data. The image data stored in the unit 8 is read and written to the recording medium 18 connected to the medical image diagnostic apparatus 1. At this time, the control unit 2 stores the image data in the image data storage destination included in the selected inspection template file. For example, when a plurality of types of recording media 18 are connected to the medical image diagnostic apparatus 1 and the MO is described as the image data storage destination in the examination template file, the control unit 2 stores the image data in the MO. To do. In this case, the display field 46 displays the name (identifier) of the MO. When the storage of the image data is completed, the control unit 2 displays the check column 46a of the display device 10 in a predetermined color. As a result, the operator can recognize that the transfer of the image data has been completed.

  As described above, by displaying the past examination content 30 and the current examination content 40 on the display device 10 at the same time, it becomes easy to compare the contents of the examination to be performed and the past examination contents. In addition, the collected or generated images are sequentially displayed on the display device 10, and when the image collection or image processing is completed, the check column is colored in a predetermined color to visualize the progress of the inspection, The operator can easily grasp the progress of the process.

  It should be noted that the process may be executed along the inspection content included in the inspection template file without displaying the past inspection content on the display device 10. In this case, after the inspection template file is read by the control unit 2 in step S02, the control unit 2 displays only the current inspection content 40 on the display device 10, and then follows the inspection plan included in the inspection template file. Thus, image data collection, image processing, image data transfer, or image data storage may be performed.

(Second operation)
Next, a second operation of the medical image diagnostic apparatus 1 according to the embodiment of the present invention will be described with reference to FIG. FIG. 7 is a flowchart for explaining a second operation of the medical image diagnostic apparatus 1 according to the embodiment of the present invention.

  First, as in the first operation, a desired inspection template is selected, further past examination contents are selected, and the current examination contents and past examination contents to be performed are displayed on the display device 10 by the control unit 2. It is displayed simultaneously on the screen 10a (step S10). For example, as illustrated in FIG. 3, the control unit 2 causes the display device 10 to display the past examination content 30 and the current examination content 40 simultaneously.

  In this state, when changing the current examination content to be performed in the future (for example, imaging conditions, image processing conditions, image data transfer destination or image data storage destination, etc.), the operator manually inputs using the operation unit 12. A desired photographing condition, image processing content, image data transfer destination, image data storage destination, and the like are input (step S11).

  Since the contents of the past examination are displayed on the monitor screen 10a of the display device 10, the operator can set the imaging conditions, the image processing conditions, the transfer destination of the image data, the storage destination of the image data, etc. While referencing, it is possible to input imaging conditions for an examination to be performed. Thereby, it becomes easy to carry out the inspection under the same conditions as the inspection carried out in the past.

  The photographing conditions input by the operation unit 12 are output to the control unit 2. Upon receiving input information such as shooting conditions from the operation unit 12, the control unit 2 outputs the information to the display device 10 and displays the shooting conditions and the like in a predetermined display field on the monitor screen 10a (step S12). Specifically, the control unit 2 outputs the input shooting conditions and the like to the display device 10, displays the input shooting conditions in the display field 43 shown in FIG. 3, and displays the input transfer destination in the display field. 45, and the input storage location is displayed in the display column 46. Thereby, the photographing conditions displayed in the display column are updated.

  In addition, the control unit 2 outputs the input imaging conditions and the like to the imaging unit 14 and the image processing unit 16 as conditions for the current examination to be performed. Then, the process is executed in accordance with the inspection plan included in the inspection template file and the conditions changed by the operator's input operation (step S13). For example, when the imaging condition is changed, the imaging unit 14 collects image data by performing scanning according to the changed imaging condition. When the content of the image processing is changed, the image processing unit 16 generates image data by performing image processing according to the changed image processing condition. The image data collected by the photographing unit 14 or the image data generated by the image processing unit 16 is temporarily stored in the image data storage unit 8.

  When the image data is collected by the photographing unit 14, the control unit 2 outputs the image data to the display device 10, and sequentially displays the images in a predetermined display field on the monitor screen 10a. As described based on FIG. 5, the control unit 2 outputs the image data collected on the display device 10, and sequentially displays the collected images on the display column 44a on the monitor screen 10a (step S14). . In this way, by sequentially displaying the collected images on the display device 10, the operator can easily check the progress of image collection.

  When the scanning by the imaging unit 14 ends (step S15, Yes), the control unit 2 receives a signal indicating the end of scanning from the imaging unit 14, and the control unit 2 is displayed on the monitor screen 10a of the display device 10. The check field 44d is displayed in a predetermined color (step S16). As a result, the operator can easily confirm the end of image collection. Further, during the execution of the scan, the control unit 2 may cause the display device 10 to display that the scan is being executed.

  Similarly to the first operation, when the image processing unit 16 performs predetermined image processing to generate image data of an arbitrary cross section, 3D image data, or the like, the control unit 2 displays the generated image data. The images are sequentially output to the device 10, and the images are sequentially displayed on the monitor screen 10 a of the display device 10. When a coronal image and a three-dimensional image are generated as in the first operation, the control unit 2 sequentially displays the coronal image in the display column 44b and sequentially displays the three-dimensional image in the display column 44c. Thus, by sequentially displaying the generated images on the display device 10, the operator can easily check the progress of the image processing. When the image processing is completed, the control unit 2 displays the check column displayed on the monitor screen 10a in a predetermined color. As a result, the operator can easily confirm the end of image generation.

  Further, similarly to the first operation, when the collected or generated image data is transferred to an external image server, when the image transfer is completed, the control unit 2 sets the check field 45a of the display device 10 to a predetermined color. Colored and displayed. Further, when the image is stored in the external recording medium 18, when the image storage is completed, the control unit 2 displays the check column 46 a of the display device 10 in a predetermined color.

  As described above, since the past examination content 30 and the current examination content 40 are displayed on the display device 10 at the same time, it is easy to change the contents of the examination to be performed while confirming the past examination contents. It becomes possible to reduce the burden of input by the operator.

  Further, when the past inspection conditions are used as the current inspection conditions, the current inspection conditions and the inspection plan may be associated with each other and stored in the inspection template storage unit 4 as a new inspection template file. In this case, when photographing conditions, image processing conditions, transfer destinations, storage destinations, and the like are input manually, the control unit 2 receives the input photographing conditions and associates the photographing conditions with the selected inspection plan. Then, a new inspection template file is stored in the inspection template storage unit 4. In this manner, by creating an inspection template using past inspection conditions, a new inspection template can be easily created. In the past, the operator had to create a large number of test template files in advance according to various diagnostic sites, diseases, and the like. However, as in this embodiment, a new test template file can be created using past test conditions. By using the inspection template, a new inspection template file can be easily created. As a result, it is possible to reduce the burden on the operator because the labor for creating a new inspection template file can be saved.

(Third operation)
Next, a third operation of the medical image diagnostic apparatus 1 according to the embodiment of the present invention will be described with reference to FIG. FIG. 8 is a flowchart for explaining the third operation of the medical image diagnostic apparatus 1 according to the embodiment of the present invention.

  First, as in the first operation and the second operation, a desired inspection template is selected, a past inspection content is further selected, and the current inspection content and the past inspection content to be performed are displayed on the monitor of the display device 10. It is displayed on the screen 10a (step S20). For example, as illustrated in FIG. 3, the control unit 2 causes the display device 10 to display the past examination content 30 and the current examination content 40.

  When using the conditions of the past examination as the conditions of the current examination to be performed from now on, the operator gives an instruction to apply the conditions of the past examination to the conditions of the current examination to be carried out using the operation unit 12 ( Step S21). For example, when applying past inspection conditions to the current inspection conditions (for example, imaging conditions, image processing conditions, image data transfer destination, image data storage destination, etc.) to be performed from now on, the operator may apply them. A command is input through the operation unit 12. If you want to perform the inspection under the same conditions as the inspections that were performed in the past, apply the conditions of the past inspection to the conditions of the current inspection that will be performed in the future. It becomes easy to implement. For example, when comparing a pre-operative state and a post-operative state, it is easier to perform the comparison under the same conditions. In such a case, it is possible to reduce the operator's input burden by automatically applying the conditions of the past examination to the conditions of the current examination to be performed.

  When receiving the application command from the operation unit 12, the control unit 2 determines whether or not the condition of the past examination is within a range that can be set in the medical image diagnostic apparatus 1 (step S22). For example, the control unit 2 determines whether or not the imaging condition of the past examination is a condition within a range that can be set in the medical image diagnostic apparatus 1. Examples of imaging conditions include the current value of the X-ray tube, the slice width, the pitch, the imaging position, the angle of the rotating mount, and the like. The control unit 2 determines that the current value of the X-ray tube in the past examination is the medical image diagnostic apparatus. In step 1, it is determined whether the value is within a settable range. In this case, an upper limit value and a lower limit value of conditions that can be set in the medical image diagnostic apparatus 1 are stored in advance in a storage device (not shown) connected to the control unit 2, and the control unit 2 Comparing the lower limit value with the conditions in the past examination (for example, the current value of the X-ray tube), determining whether the conditions in the past examination are included in the range of the upper limit value and lower limit value of the settable condition I do.

  When the control unit 2 determines that the past examination conditions are within a settable range (step S23, Yes), the past examination conditions are applied to the current examination conditions to be performed (step S24). For example, when it is determined that the tube current value of the past examination is within a settable range, the value of the tube current is used as the imaging condition of the current examination.

  Then, the control unit 2 outputs the conditions of the past examination as the conditions of the current examination to be performed to the display device 10 and displays the imaging conditions and the like in a predetermined display column on the monitor screen 10a. For example, when the imaging conditions of the past examination are applied as the imaging conditions of the current examination, the imaging conditions of the past examination are displayed in the display field 43 on the monitor screen 10a. Further, the control unit 2 outputs the past examination conditions to the imaging unit 14 and the image processing unit 16. Specifically, the control unit 2 outputs imaging conditions for past examinations to the imaging unit 14 and outputs image processing conditions for past examinations to the image processing unit 16.

  And a process is performed according to the set inspection plan and conditions (step S26). For example, the imaging unit 14 collects image data by performing scanning according to the imaging conditions of the past examination. Further, the image processing unit 16 generates image data by performing image processing according to the image processing conditions of the past examination.

  When the image data is collected by the photographing unit 14, the control unit 2 outputs the image data to the display device 10, and sequentially displays the images in a predetermined display field on the monitor screen 10a. As described with reference to FIG. 5, the control unit 2 sequentially displays the collected images in the display field 44a.

  In this way, past inspection conditions can be automatically applied to the current inspection conditions to be performed and inspections can be executed. This eliminates the need for the operator to input imaging conditions, and allows manual input. It is possible to prevent erroneous input due to the above and reduce the burden on the operator. Further, since it is possible to collect image data under the same conditions as in the past examination, it is possible to easily compare with images obtained in the past.

  In addition, when the control unit 2 determines that the conditions of the past examination are not within the settable range (No at Step S23), the control unit 2 is currently executing the settable conditions in the medical image diagnostic apparatus 1. This is applied to the inspection conditions (step S25). For example, when the value of the tube current in the past examination exceeds the settable upper limit value, the control unit 2 applies the settable upper limit value to the condition of the current examination to be performed from now. When the tilt angle of the rotating gantry in the past inspection exceeds the settable angle, the control unit 2 applies the settable upper limit value to the conditions of the current inspection to be performed from now. In this case, the control unit 2 outputs a settable upper limit value to the display device 10 as a condition to be implemented from now on, and displays shooting conditions and the like in a predetermined display field on the monitor screen 10a. For example, when the tube current value of the past examination exceeds a settable value, the control unit 2 displays the settable tube current value in the display column 43 on the monitor screen 10a. In addition, the control unit 2 outputs a settable upper limit value to the photographing unit 14 or the image processing unit 16.

  Then, as described above, the process is executed according to the set inspection plan and conditions (step S26).

  As described above, even if the apparatus cannot use the conditions of the past examination as it is, the image obtained by the past examination can be obtained by performing scanning or image processing under conditions close to the conditions of the past examination. It is possible to obtain an image for comparison. As a result, it is possible to save the operator from inputting photographing conditions and the like, to prevent erroneous input due to manual input, and to reduce the burden on the operator.

  Further, when it is determined that the conditions of the past examination are not within the settable range, the control unit 2 may display the display column 43 with the column blank. In this case, the imaging condition is set by the operator inputting the imaging condition using the operation unit 12.

  Further, when the past inspection conditions are used as the current inspection conditions, as in the second operation described above, the current inspection conditions and the inspection plan are associated with each other as a new inspection template file. 4 may be stored.

(Fourth operation)
Next, a fourth operation of the medical image diagnostic apparatus 1 according to the embodiment of the present invention will be described with reference to FIG. FIG. 9 is a flowchart for explaining a fourth operation of the medical image diagnostic apparatus 1 according to the embodiment of the present invention.

  First, the control unit 2 displays information (for example, a patient ID, a patient name, or an examination number) for specifying the contents of examinations performed in the past (past examination contents) on the monitor screen of the display device 10. When there are a plurality of past examination contents, the control unit 2 causes the display device 10 to display a list of examination numbers. Then, an operator such as a radiologist selects desired past examination contents from a plurality of past examination contents displayed on the display device 10 using the operation unit 12 (step S30). For example, the contents of the examination performed in the past for the patient to be examined are selected. Specifically, when imaging a post-surgical region, the examination content (past examination content) performed before the surgery is selected. Further, the operator may directly input a patient ID, a patient name, and the like using the operation unit 12.

  When past examination contents are selected or a patient ID is input by the operator, information for specifying the selected past examination contents from the operation unit 12 to the control unit 2 (for example, patient ID, patient name, examination number, etc.) ) Is output. When the control unit 2 receives the information specifying the designated past examination content, the control unit 2 searches the past examination content selected from the plurality of past examination contents stored in the past examination data storage unit 6 and stores the past examination data storage. The past examination content selected from the unit 6 is read (step S31).

  When the past examination content is read from the past examination data storage unit 6, the control unit 2 determines whether or not the past examination condition is within a range that can be set in the medical image diagnostic apparatus 1 (step S32). For example, the control unit 2 determines whether or not the imaging condition of the past examination is a condition within a range that can be set in the medical image diagnostic apparatus 1. For example, the control unit 2 determines whether or not the value of the tube current in the past examination is a value within a range that can be set in the medical image diagnostic apparatus 1. Specifically, an upper limit value and a lower limit value of conditions that can be set in the medical image diagnostic apparatus 1 are stored in advance in a storage unit in the control unit 2, and the control unit 2 stores the upper limit value stored in the storage unit. In addition, the lower limit value is compared with the conditions in the past examination (for example, the current value of the X-ray tube), and it is determined whether the conditions in the past examination are included in the range of the upper limit value and the lower limit value of the settable condition. I do.

  When the control unit 2 determines that the conditions for the past examination are within a settable range (step S33, Yes), the conditions for the past examination are applied to the conditions for the current examination to be performed (step S34). For example, when it is determined that the tube current value of the past examination is within a settable range, the value of the tube current is used as the imaging condition of the current examination.

  Then, the control unit 2 outputs the past examination conditions as conditions for the current examination to be performed to the display device 10 and displays the imaging conditions and the like in a predetermined display field on the monitor screen 10a (step S36). . At this time, the control unit 2 displays the past examination content 30 and the current examination content 40 to be performed on the monitor screen 10a of the display device 10. For example, when the imaging conditions of the past examination are applied as the imaging conditions of the current examination, the control unit 2 displays the imaging conditions of the past examination in the display column 31 and the past examination applied in the display column 41 of the current examination. Display the shooting conditions.

  Then, the process is executed in accordance with the set inspection plan and conditions (step S37). For example, the imaging unit 14 collects image data by performing scanning according to the imaging conditions of the past examination. Further, the image processing unit 16 generates image data by performing image processing according to the image processing conditions of the past examination.

  When the image data is collected by the photographing unit 14, the control unit 2 outputs the image data to the display device 10, and sequentially displays the images in a predetermined display field on the monitor screen 10a. As described with reference to FIG. 5, the control unit 2 sequentially displays the collected images in the display field 44a.

  In this way, past inspection conditions can be automatically applied to the current inspection conditions to be performed and inspections can be executed. This eliminates the need for the operator to input imaging conditions, and allows manual input. It is possible to prevent erroneous input due to the above and reduce the burden on the operator.

  In addition, when the control unit 2 determines that the conditions of the past examination are not within the settable range (No at Step S33), the control unit 2 is currently set to the conditions that can be set in the medical image diagnostic apparatus 1. The inspection conditions are applied (step S35). Similar to the third operation, for example, when the value of the tube current in the past examination exceeds the settable upper limit value, the control unit 2 sets the settable upper limit value in the current examination condition. Applies to Then, the control unit 2 outputs the settable upper limit value as a condition to be implemented to the display device 10 and displays the photographing condition and the like in a predetermined display field on the monitor screen 10a (step S36). At this time, the control unit 2 displays the past examination content 30 and the current examination content 40 to be performed on the monitor screen 10a of the display device 10.

  And as above-mentioned, a process is performed according to the set inspection plan and conditions (step S37).

  As described above, even if the apparatus cannot use the conditions of the past examination as it is, the image obtained by the past examination can be obtained by performing scanning or image processing under conditions close to the conditions of the past examination. It is possible to obtain an image for comparison. As a result, it is possible to save the operator from inputting photographing conditions and the like, to prevent erroneous input due to manual input, and to reduce the burden on the operator. In addition, since it is possible to collect image data under the same conditions as those for past examinations, it is possible to easily compare with images obtained in the past.

  Further, when it is determined that the conditions of the past examination are not within the settable range, the control unit 2 may display the display column 43 with the column blank. In this case, the imaging condition is set by the operator inputting the imaging condition using the operation unit 12.

  Further, when the past inspection conditions are used as the current inspection conditions, a new inspection template file is created by associating the current inspection conditions with the inspection plan as in the second operation and the third operation described above. May be stored in the inspection template storage unit 4.
