FIG. 4 is an explanatory diagram showing an example of an image after processing in which a reference value of window width is specified. In the example of FIG. 4, when specifying the window width (WW), the reference value of the window width is specified. The specific condition setting unit 521 sets a plurality of specific conditions within a predetermined range including the reference value based on the designation of the reference value for processing. In the example of FIG. 4, by specifying WW=400 as the reference value, WW is specified at intervals of 50 within a predetermined range from 200 to 600 including the reference value of 400. Each WW value from 200 to 600 is a specific condition. It should be noted that the images schematically illustrated in association with the respective WW values are examples, and do not necessarily accurately reflect the actual WW values.

In this way, by designating a specific condition that serves as a reference value among the specific conditions that specify the content of the process, it is possible to set a plurality of specific conditions within a predetermined range that includes the specific condition. The predetermined range from 200 to 600 may be predetermined with respect to the reference value, and the width of the predetermined range may be changed according to the reference value.

The image generation unit 522 displays images resulting from window processing using values of WW from 200 to 600 in the thumbnail area 204 as result candidates.

With the above configuration, it is possible to set a plurality of specific conditions simply by determining the reference value for specifying the content of the process, thereby improving workability.

FIG. 5 is an explanatory diagram showing an example of an image after processing in which the upper limit value and the lower limit value of the window width are specified. In the example of FIG. 5, when specifying the window width, the lower limit (WW=200) and the upper limit (WW=600) of the window width are specified. The specific condition setting unit 521 sets a plurality of specific conditions within the specified range of processing. The specified range may be an upper limit value, a lower limit value, or an upper limit value and a lower limit value. In the example of FIG. 5, by specifying WW=200 as the lower limit and WW=600 as the upper limit, WW is specified at intervals of 50 within the range from 200 to 600. . Each WW value from 200 to 600 is a specific condition. In the example of FIG. 5, it is possible to select an image with a WW value of 250, which is considered to be optimal by the medical staff, from among a plurality of displayed images (result candidates). It should be noted that the images schematically illustrated in association with the respective WW values are examples, and do not necessarily accurately reflect the actual WW values.

In this way, by designating the upper limit value and the lower limit value among the specific conditions for specifying the content of the process, it is possible to set a plurality of specific conditions within a range including the specific condition. The number of specific conditions to be specified within the range may be determined in advance, and may be slightly changed according to the upper limit or lower limit.

The image generation unit 522 displays images resulting from window processing using values of WW from 200 to 600 in the thumbnail area 204 as result candidates.

With the above configuration, it is possible to set a plurality of specific conditions simply by determining the range for specifying the content of the process, thereby improving workability.

As described above, if one process is specified, a plurality of specific conditions for specifying the details of the process are set, and the resulting image processed based on each of the plurality of specific conditions is output. It eliminates the need for trial and error to determine the parameters one by one, reducing the number of executions until the desired result is obtained, and efficiently obtaining the optimum result.

Further, the specific condition setting unit 521 sets a plurality of specific conditions for specifying the content of the second process based on the specification of the second process for the image. Here, the second processing is processing different from the first processing.

The image generation unit 522 generates a processing result based on a plurality of combined specific conditions obtained by combining a plurality of specific conditions for specifying the details of the first process and a plurality of specific conditions for specifying the details of the second process. Output each subsequent image. When an image is displayed on a display screen, there is more than one process to be performed, and when different processes can be performed at the same time, a combination of a plurality of specific conditions that specify the content of each process is combined based on a combination specific condition. , can determine the parameters for performing different processes simultaneously.

Specifically, the image generator 522 can perform processing based on the combination specific condition, generate images after processing, and display them in the thumbnail area 204 .

FIG. 6 is an explanatory diagram showing an example of an image after processing in which the window width and window value are specified. Here, if the window width (WW) is the content of the first processing, the window value (WL) is the content of the second processing. In the example of FIG. 6, for the sake of convenience, processing results based on nine combined specific conditions obtained by combining three specific conditions of WW=200, 300, 400 and three specific conditions of WL=-200, 0, +200 The latter nine images are shown. In this specification, the images shown in association with the values of WW and WL do not accurately reflect the values of WW and WL for the sake of convenience, but the actual images are the WW values. and accurately reflects the WL value.

FIG. 7 is an explanatory diagram showing an example of an image after processing specifying SPIN and DOLLY. Here, if SPIN is the content of the first processing, DOLLY is the content of the second processing. In the example of FIG. 7, for convenience, five specific conditions SPIN=−90°, −45°, 0, +45°, +90° and DOLLY=x0.25, x0.5, x1.0, x2.0, 25 images after processing results based on 20 combination specific conditions obtained by combining with 5 specific conditions of x4.0 are displayed.

With the above-described configuration, if different processes are specified, a plurality of combination specific conditions are set for simultaneously performing different processes, and images resulting from processing based on each of the plurality of combination specific conditions are output. It eliminates the need for trial and error for parameters that determine display conditions one by one, and it is possible to efficiently obtain optimal results. In addition, it is possible to perform processing while confirming the results of multiple types of processing, and to reduce the number of processing trials and the number of operations.

FIG. 8 is an explanatory diagram showing a first display example of the frequency of use of specific conditions. The image after processing is the same as in the case of FIG. In FIG. 8, images after processing are displayed in different modes according to the frequency of use of the specific condition or combination specific condition. For example, since the combination specific condition of WW=300 and WL=-200 and the combination specific condition of WW=400 and WL=+200 are frequently used, the background or frame of the image is displayed in a darker color. Further, since the combination specific condition of WW=400 and WL=0 and the combination specific condition of WW=200 and WL=0 are used rather frequently, the background or frame of the image is displayed with a slightly darker color. In addition, a combination specific condition of WW=400 and WL=-200, a combination specific condition of WW=300 and WL=0, a combination specific condition of WW=200 and WL=+200, and a combination specific condition of WW=300 and WL=+200 Since the frequency of use of the condition is rather low, the background or frame of the image is displayed with a slightly lighter color.

FIG. 9 is an explanatory diagram showing a second display example of the frequency of use of specific conditions. The image after processing is the same as in the case of FIG. In FIG. 9, images after processing are displayed in different modes according to the frequency of use of the specific condition or combination specific condition. The difference from FIG. 8 is that the background or frame color of the image can be changed according to the frequency of use. In the example of FIG. 9, for convenience, each pattern corresponds to red, green, and blue. If the frequency of use is high, it is displayed in red. If the frequency of use is medium, it is displayed in green. If it is low, it can be displayed in blue. Although not shown, the frequency of use of the specific condition is the same as the frequency of use of the combination specific condition.

As described above, the image generation unit 522 can output a plurality of processed images in different display modes according to the frequency of use of a plurality of specific conditions or combined specific conditions. The different display modes include, for example, changing the shade of the background or frame of the image, and changing the color. The higher the frequency of use, the more conspicuous the display.

With the above-described configuration, it is possible to visualize the frequency of use of specific conditions or specific combination conditions that specify the content of processing. For example, what specific conditions or specific combination conditions should be used to obtain the optimum result. can be determined based on the past processing, the time required to reach the optimum processing content can be shortened.

It should be noted that the visualization of the frequency of use of the specific condition or combination of specific conditions as described above can be shared not only by individual medical professionals such as doctors, but also by multiple medical professionals within a group. A database may be created for each. Also, a database may be created for each part of the human body or for each symptom and shared among a plurality of medical professionals.

Next, updating (resetting) of specific conditions or combination specific conditions will be described.

FIG. 10 is an explanatory diagram showing a first example of updating specific conditions. In FIG. 10, the diagram on the left shows the state before updating, and the diagram on the right shows the state after updating. The figure on the left shows nine combinations obtained by combining the three specific conditions of SPIN = -90°, 0, +90° and the three specific conditions of DOLLY = x0.25, x1.0, x4.0. Nine images after processing results based on specific conditions are displayed. In FIG. 10, it is assumed that one image (in FIG. 10, an image after processing based on specific conditions of SPIN=90° and DOLLY=x1.0) is selected from nine images. In this case, a specific condition corresponding to the selected image is set as a reference value, and a predetermined number of specific conditions are set within a predetermined range including the reference value. In the example of FIG. 10, with the selected image SPIN=90° as the reference value, SPIN=0 is assigned, and three images are generated within the range including the reference value (the range between SPIN=−90° and SPIN=90°). Set specific conditions.

Note that DOLLY of the selected image is x1.0, which is the center value in the range, so the specific condition for DOLLY has not been updated. If an image with DOLLY=x0.25 is selected, DOLLY=x1.0 is assigned with DOLLY=x0.25 of the selected image as a reference value, and a range including the reference value (DOLLY=x0.25° and DOLLY=x4.0), three specific conditions can be set.

As described above, when one of the displayed images is selected, the specific condition setting unit 521 sets the specific condition corresponding to the selected image as a reference value, and sets the range including the reference value. Set multiple specific conditions to .

With the above configuration, when each image after the processing result is displayed, by simply selecting the image that is considered to be close to the optimum result from among the displayed images, further processing is performed based on the specific conditions of the image. By comparing images after processing results based on a plurality of surrounding specific conditions, it is possible to easily search for an image that is closer to the optimal result. As a result, it is possible to shorten the time required to reach the optimum processing content.

FIG. 11 is an explanatory diagram showing a second example of updating specific conditions. In FIG. 11, the diagram on the left shows the state before updating, and the diagram on the right shows the state after updating. The figure on the left shows nine combinations obtained by combining the three specific conditions of SPIN = -90°, 0, +90° and the three specific conditions of DOLLY = x0.25, x1.0, x4.0. Nine images after processing results based on specific conditions are displayed. In FIG. 11, it is assumed that one image (in FIG. 11, the image after processing based on each specific condition of SPIN=90° and DOLLY=x1.0) is selected from nine images. In this case, the specific condition corresponding to the selected image is set as a reference value, and the specific condition is set within a range including the reference value. In the example of FIG. 11, unlike the example of FIG. 10, the range for setting a plurality of specific conditions is narrowed. That is, with SPIN=90° of the selected image as the reference value, SPIN=0 is assigned, and three specific conditions are set within the range including the reference value (the range between SPIN=−45° and SPIN=45°). are doing. Similarly, with DOLLY=x1.0 of the selected image as a reference value, DOLLY=x1.0 is assigned, and within the range including the reference value (DOLLY=x0.5 and DOLLY=x2.0) has set three specific conditions.

As described above, when one of the displayed images is selected, the specific condition setting unit 521 sets the specific condition corresponding to the selected image as a reference value, and sets the range including the reference value. can be set to a narrower range than the original range, and a plurality of specific conditions can be set. Further, when one of the displayed images is selected, the specific condition setting unit 521 sets the specific condition corresponding to the selected image as a reference value, and sets the range including the reference value to the original image. A plurality of specific conditions may be set with a wider range than the range. In other words, the specific condition setting section 521 can change the range for setting a plurality of specific conditions according to an operation on one of the displayed images.

FIG. 12 is an explanatory diagram showing a third example of updating specific conditions. In FIG. 12, the diagram on the left side is similar to FIGS. 10 and 11. FIG. In the diagram on the left side of FIG. 12, one image (in FIG. 12, the image after processing based on each specific condition of SPIN=90° and DOLLY=x1.0) is selected and selected. When a predetermined operation is performed on the image obtained, a plurality of specific conditions can be updated (reset) according to the operation. Although the image is not shown in FIG. 12 for convenience, the image is actually displayed.

In the example of FIG. 12, the predetermined operation is an operation of moving the cursor upward, downward, rightward, and leftward on the selected image or on the image, but the predetermined operation is limited to the example of FIG. not. As shown in the right diagram of FIG. 12, when an upward movement operation is performed on the selected image, the DOLLY range widens, such as from x0.10 to x6.0. Also, when a downward movement operation is performed on the selected image, the range of DOLLY is narrowed, such as from x0.5 to x2.0. Also, when a rightward movement operation is performed on the selected image, the range of SPIN is widened, such as from -120° to +120°. Also, when a leftward movement operation is performed on the selected image, the range of SPIN is narrowed, such as from -45° to +45°.

As described above, the specific condition setting unit 521 can determine the width of the range for setting a plurality of specific conditions according to the details of the operation performed on the selected one image. For example, by selecting an image that is considered to be close to the optimal result from among the displayed images and performing a predetermined operation on the selected image, the range for setting multiple specific conditions is normally set. can be wider or narrower than the predetermined range provided.

With the above-described configuration, when a plurality of images after processing results are displayed, it is possible to confirm the processing results by widening the range of the specific conditions for a desired image among the plurality of images, or to confirm the processing results by applying the specific conditions. It is possible to confirm the processing result by narrowing the range, and shorten the time required to reach the optimum processing content.

FIG. 13 is an explanatory diagram showing a fourth example of updating specific conditions. In FIG. 13, the diagram on the left shows the state before updating, and the diagram on the right shows the state after updating. The figure on the left is the same as in FIG. 11, with three specific conditions of SPIN=−90°, 0, +90° and three specific conditions of DOLLY=x0.25, x1.0, x4.0. Nine images after processing results based on nine combination specific conditions obtained by combining are displayed. Although the image is not shown in FIG. 13 for convenience, the image is actually displayed. In FIG. 13, it is assumed that one image (in FIG. 13, an image after processing based on specific conditions of SPIN=90° and DOLLY=x1.0) is selected from nine images. In this case, the number of specific conditions to be set is changed using the specific condition corresponding to the selected image as a reference value. In the example of FIG. 13, as shown in the diagram on the right, five specific conditions SPIN=−90°, −45°, 0, +45°, +90° and DOLLY=x0.25, x0.5, x1. Twenty-five images after processing results based on twenty-five combination specific conditions obtained by combining with five specific conditions of 0, x2.0, and x4.0 are displayed.

As described above, the specific condition setting unit 521 can change the number of specific conditions to be set according to an operation on one of the displayed images. Specifically, when one of the displayed images is selected, the specific condition setting unit 521 sets the specific condition corresponding to the selected image as a reference value, and sets the number of original specific conditions. A larger number of specific conditions may be set, or a smaller number of specific conditions than the original number of specific conditions may be set.

With the above-described configuration, when the images after the processing result are displayed respectively, the processing result can be confirmed by increasing the number of specific conditions to be set for the desired image among the plurality of displayed images, or , the number of specific conditions to be set can be reduced to check the processing results, and the time required to reach the optimum processing content can be shortened.

FIG. 14 is an explanatory diagram showing a fifth example of updating specific conditions. In FIG. 14, the upper diagram shows the state before update, and the lower diagram shows the state after update. The upper diagram shows five images after processing results based on five specific conditions from WW=100 to 500. In FIG. 14, for example, assume that two images, an image with WW=400 and an image with WW=500, are selected. In this case, the specific condition for each selected image is defined as a range, and the specific condition is set within the range. In the example of FIG. 14, five specific conditions of WW=400, 425, 450, 475, and 500 are set within the range of WW=400 and WW=500.

FIG. 15 is an explanatory diagram showing a sixth example of updating specific conditions. In FIG. 15, the upper diagram shows the state before update, and the lower diagram shows the state after update. The upper diagram shows five images after processing results based on five specific conditions from WW=100 to 500. In FIG. 15, for example, assume that two images, an image with WW=200 and an image with WW=400, are selected. In this case, the specific condition for each selected image is defined as a range, and the specific condition is set within the range. In the example of FIG. 15, five specific conditions of WW=200, 250, 300, 350, and 400 are set within the range of WW=200 and WW=400.

As described above, when a plurality (for example, two) of the displayed images are selected, the specific condition setting unit 521 sets the specific condition corresponding to the selected images as a range. , set multiple specific conditions in the range.

With the above-described configuration, when a plurality of images after processing are displayed, the specific conditions between two images can be specified in more detail among the plurality of images. can shorten the time to Also, as shown in FIGS. 14 and 15, the closer the two images to be selected, the finer the interval (the interval is 25 in the example of FIG. 14, whereas the interval is 50 in the example of FIG. 15). A specific condition can be set, and by changing the positions of the two images to be selected, the interval between the specific conditions to be updated can be adjusted.

Although not shown, when images based on specific conditions (for example, SPIN and DOLLY) specifying the contents of two processes are arranged in a matrix and displayed as shown in FIG. Two images aligned horizontally can be selected, and two images aligned diagonally can also be selected.

Next, an example of simultaneously displaying an image after processing with respect to a volume rendering (VR) image will be described.

FIG. 16 is an explanatory diagram showing a first example of simultaneous display of a processed image with respect to a volume rendering image. In FIG. 16, the diagram on the left side can be displayed in the image display area 201 in FIG. 3, for example. 16 can be displayed in the thumbnail area 204 by operating the XYZ icons 202h in the process list display area 202 shown in FIG. In the example of FIG. 16, images viewed from the front, back, top, bottom, left, and right are displayed as specific viewpoint positions on the XYZ coordinates of the volume rendering image. In this case, the specification condition setting unit 521 specifies a plurality of viewpoint positions (for example, front, back, top, bottom, left, right).

In this way, since images viewed from simultaneously specified angles are displayed at the same time, changing a filter (for example, specifying a region, extracting a part or object, etc.) for a volume rendering image can be applied to images viewed from multiple specified angles. are immediately reflected at the same time, and the operation time and confirmation time can be shortened.

FIG. 17 is an explanatory diagram showing a second example of simultaneous display of the processed image with respect to the volume rendering image. In FIG. 17, the diagram on the left side can be displayed in the image display area 201 in FIG. 3, for example. 17 can be displayed in the thumbnail area 204 by operating the CAMERA icon 202i in the process list display area 202 shown in FIG. In the example of FIG. 17, images of volume rendering images viewed from six cameras, cameras 1 to 6, as specific viewpoint positions are displayed. In this case, the specific condition setting unit 521 identifies a plurality of viewpoint positions (for example, positions of cameras 1 to 6).

In this way, instead of displaying a volume rendering image at a fixed angle (example in FIG. 16), multiple camera positions are fixed and images viewed from each camera's viewpoint are displayed simultaneously. This allows simultaneous viewing from a plurality of viewpoints, reduces rotation operations of the volume rendering image, and reduces work time.

As described above, the image generator 522 displays a plurality of images after processing results based on a plurality of viewpoint positions. As a result, for example, images viewed from a plurality of simultaneously specified viewpoint positions can be displayed simultaneously with respect to the volume rendering image, and the operation time and image confirmation time can be shortened.

FIG. 18 is an explanatory diagram showing a third example of simultaneous display of the processed image with respect to the volume rendering image. Although not shown, the specific condition setting unit 521 can set, for example, stomach, heart, lung, liver, large intestine, and small intestine as specific conditions by designating part extraction processing. For extraction processing of each part, an appropriate method such as a method of extracting based on the coordinate position in the image, a method of extracting by performing shape analysis, or the like can be used.

The image generator 522 can display the extracted image of each part in the thumbnail area 204 . By applying the adjusted color map to each extracted part, it is possible to simultaneously display the application results for each part and to display the desired part more clearly. As a result, it is possible to reduce the number of operations required for switching parts, and shorten the operation time or the image confirmation time.

FIG. 19 is an explanatory diagram showing a fourth example of simultaneous display of the processed image with respect to the volume rendering image. The six images shown in FIG. 19 are similar to the example in FIG. The event determination unit 523 determines whether or not a predetermined event exists in a plurality of images after processing results based on a plurality of viewpoint positions. The predetermined event can be, for example, an abnormal event such as a bone fracture, and the predetermined event can be determined in advance by predetermined image processing. In the example of FIG. 19, it is determined that the image viewed from camera 6 has a fracture.

The image generator 522 displays an image determined to have an event by the event determination unit 523 in a manner different from other images (images without an event). Different modes may display an alert on the image seen from the camera 6, may display a frame on the image, or blink the background or frame of the image, as shown in FIG. 19, for example. may be displayed.

With the above-described configuration, images at a plurality of viewpoint positions are displayed simultaneously, and if a predetermined event is present in one of the images, the presence or absence of the event can be immediately confirmed. The operation time can be shortened as compared with the case of displaying them one by one.

FIG. 20 is an explanatory diagram showing a fifth example of simultaneous display of the processed image with respect to the volume rendering image. In FIG. 20, an MPR (Multi-Planar Reconstruction) image is displayed in addition to the display example shown in FIG. MPR images consist of three cross-sectional images: a body axis cross-section (axial cross-section, axial cross-section) horizontal to the body, a sagittal cross-section (sagittal cross-section), and a cross-sectional coronal cross-section (coronal cross-section). consists of Also, an axial section, a sagittal section, and a coronal section are displayed in the volume rendering image.

That is, the image generation unit 522 displays a volume rendering image, and displays a cross-sectional image (MPR image) in a predetermined cross section (axial cross section, sagittal cross section, and coronal cross section) corresponding to the image after the processing result based on the viewpoint position. and display the cross section in the volume rendering image.

With the above-described configuration, it becomes clear in which cross-section the image after the processing result based on the viewpoint position is the image viewed with respect to the volume rendering image, and the volume rendering image can be used to assist diagnosis. can.

In addition, the image generation unit 522 can update and display the cross-sectional image according to the operation on the cross-section in the volume rendering image. For example, moving the coronal slice within the volume rendered image updates (eg, translates, rotates, etc.) the coronal slice image. The same applies to axial and sagittal sections. As a result, cooperation between the volume rendering image and the cross-sectional image can be enhanced, and the volume rendering image can be used to assist diagnosis. Note that the volume rendering image can be transparently displayed or wire-displayed during movement of the cross section in the volume rendering image.

Next, visualization (tree formation) of the processing history will be described.

FIG. 21 is an explanatory diagram showing a first example of display of processing history. Assume that the image shown in FIG. 21 is an image selected from a plurality of images based on a plurality of specific conditions set corresponding to each process. In FIG. 21, a series of processes are represented by symbols a1 to a5 and b1 to b4. Here, the processes b1, b2, b3, and b4 are processes whose operations have been canceled and returned to the original state. For example, it indicates that the processes b1 and b2 are canceled and the process returns to the process a2. It also indicates that the processes b3 and b4 are canceled and the process returns to the process a4.

In general, the canceled process disappears from the history and may not remain in the process history. However, in the present embodiment, the processing history display unit 524 displays the processing result based on a specific condition selected from among a plurality of specific conditions for specifying the content of each process based on designation of a series of processes for an image. can be stored and displayed for each series of processing.

For example, one process (for example, process b1 in FIG. 21) is designated, a plurality of images after processing results based on each of a plurality of specific conditions specifying the content of the process are displayed, and among the displayed images When one image is selected from, the selected image (image corresponding to process b1) and the specific condition corresponding to the image (Pan(x-100, y-100) in the example of FIG. 21) are stored. can do.

Next, cancel the one process (for example, process b1 in FIG. 21), newly specify another process (for example, process a2 in FIG. 21), and specify the contents of the other process. When a plurality of images after processing results based on each condition are displayed, and one image is selected from among the plurality of displayed images, the selected image (image corresponding to processing a2) and the identification corresponding to the image are displayed. The condition (dolly(x0.3)) can be stored.

With the above-described configuration, even when one process is performed and then the process is canceled and another process is performed, for each series of processes, the specific conditions are selected from among a plurality of specific conditions that specify the contents of each process. By storing images after processing results based on specific conditions, it is possible to display the processing history and reproduce the details of the previously performed processing. For example, in the example of FIG. 21, it is possible to easily return from the image corresponding to process a5, which is the latest result, to the image corresponding to process b3, which is the desired result. In addition, compared to displaying a list of processing histories using characters, etc., images after a series of processing results are displayed as a history. and processing time can be shortened.

FIG. 22 is an explanatory diagram showing a second example of display of processing history. In FIG. 22, a series of actually performed processes are denoted by reference numerals a1 to a5, b2, and c2. Here, the processes b2 and c2 are processes whose operations have been canceled and restored to the original state. For example, it indicates that the processes b2 and c2 are canceled and return to the process a2. Further, processes b3 to b5 and c3 to c5 are processes automatically performed by the process history display unit 524, not processes specified by the medical staff.

That is, the processing history display unit 524 displays a combination of specific conditions selected from among a plurality of specific conditions for specifying the content of each process based on the designation of a series of processes for an image. The processed image is stored and displayed.

The combined specific conditions obtained by combining the specific conditions are not only the specific conditions selected from a plurality of specific conditions that specify the details of the processing specified for execution, but also the details of the processing not actually specified. It also includes specific conditions that specify the

For example, as shown in FIG. 22, when processes a3, a4, and a5 are performed in order after process a2, the image obtained by process b2 canceled before process a2 is also processed. Processing b3, b4 and b5 similar to a3, a4 and a5 are performed in order, and the selected image after the processing result and the specific conditions corresponding to the image are stored and displayed. Similarly, the same processes c3, c4 and c5 as the processes a3, a4 and a5 are performed in order on the image obtained by the process c2 canceled before the process a2. The image and the specific conditions corresponding to the image are stored and displayed.

With the above configuration, even if the process is not actually specified, it is possible to check the processing result based on the combination specific condition obtained by combining each specific condition specified in the series of processes, and efficiently optimize the process. good results can be obtained. In the example of FIG. 22, the image corresponding to the process b5, which is the ideal result, can be easily reached from the latest result, the image corresponding to the process a5. It also makes it easy to find the best results and manipulate them when a different set of treatments than what the healthcare professional thought would give better results might have been the best results. It is possible to improve the quality and shorten the processing time.

FIG. 23 is an explanatory diagram showing a third example of display of processing history. FIG. 23 shows an example of visualizing historical paths. That is, the processing history display unit 524 displays a designation order identifier indicating the designation order of a series of processes for an image. In the example of FIG. 23, thick arrows are illustrated. This makes it possible to visualize the order of processing leading to the optimum result, and to provide a procedure for obtaining the optimum processing result for similar images. For example, it is possible to obtain ideal results in a short period of time by treating similar parts of the body in similar procedures. In addition, if such history paths are stored in a database for each part and shared, useful information can be obtained when other medical workers view similar parts.

FIG. 24 is a block diagram showing another example of the configuration of the display processing section 52 of this embodiment. As shown in FIG. 24, the display processing unit 52 can be composed of a CPU 526, a ROM 527, a RAM 528, a recording medium reading unit 529, and the like. A computer program recorded on the recording medium 1 can be read by the recording medium reading unit 529 and stored in the RAM 528 . By causing the CPU 526 to execute the computer programs stored in the RAM 528, the processes performed by the specific condition setting unit 521, the image generation unit 522, the event determination unit 523, and the processing history display unit 524 can be executed. Note that the CPU 526 is a general term for processors, processor devices, processing units, and the like, and can be composed of one or more. Also, the computer program can be downloaded via a network such as the Internet instead of being read by the recording medium reading unit 529 .

Next, the operation of the display device 50 of this embodiment will be described.

25 and 26 are flowcharts showing an example of display processing by the display device 50 of this embodiment. In the following, for the sake of convenience, the display processing unit 52 will be described as the subject of processing. The display processing unit 52 identifies a medical image (S11).

The display processing unit 52 acquires the specified medical image from the server 20 (S12). The acquired medical image can be stored in the storage unit 55 . The display processing unit 52 displays the medical image (S13). The display of the medical image is, for example, the one illustrated in FIG. 3, but is not limited to this.

The display processing unit 52 determines whether or not the first process is designated (S14), and if there is no designation (NO in S14), continues the processing of step S14. If specified (YES in S14), the display processing unit 52 sets a plurality of specific conditions for specifying the content of the first process (S15).

The display processing unit 52 determines whether or not there is an update operation for the specific condition (S20), and if there is an update operation (YES in S20), updates the specific condition (S21), and displays the result of processing based on the updated specific condition. are displayed (S22), and the process of step S23, which will be described later, is performed.

When there is no update operation of the specific condition (NO in S20), the display processing unit 52 determines whether or not there is a selection operation of the displayed images (S23). If there is a selection operation (YES in S23), the display processing unit 52 stores the selected image and the specific condition corresponding to the image (S24), and performs the processing of step S25 described later.

If there is no selection operation (NO in S23), the display processing unit 52 determines whether there is an operation to display the processing history (S25), and if there is a display operation (YES in S25), displays the processing history (S26). ), the process of step S27, which will be described later, is performed.

In addition, by displaying a plurality of states in which parameters are fixed (for example, selected parameters and images after processing results based on the parameters) for each process, it is possible to switch states for confirmation (for example, change parameters). Work required can be reduced. In addition, compared to the case of displaying the past history in text, according to the present embodiment, the comprehensive display of the history and the continuation of the processing for the history reduce the time required for history search, and it takes time to obtain the optimum result. can save time.

In addition, when a follow-up observation is performed by referring to a plurality of images taken in the past, the work of searching for images of the same site becomes complicated, and it may take time to interpret the images. For this reason, when diagnosing the same imaging region by imaging it on different examination days, a method of displaying a plurality of images of the same region in chronological order is conceivable. However, the images displayed in chronological order are not necessarily the optimum images. Even in such a case, it is necessary to make trial and error for various parameters one by one for each image displayed in chronological order, which requires time and effort to obtain the optimum result. However, according to the present embodiment, a plurality of parameters can be set simply by designating the processing, and a plurality of images after processing based on the set parameters are displayed. Therefore, optimal results can be efficiently obtained. .

For example, the server 20 can have a configuration similar to that of the display processing unit 52 . In this case, the display device 50 outputs the operation performed by the operation input unit 53 to the server 20 , the server 20 performs required display processing according to the operation, and transmits the processing result to the display device 50 . should be
