The control unit 17 may control the display unit 16 so as to move the position of the measurement cursor on the ultrasonic image according to the correction of the measurement value of the BPD.

The control unit 17 displays the print button 45, the report save button 46, the report output button 47, the save button 48, and the non-display button 49 in areas other than the display areas 22, 24, and 26 on the inspection screen 20. 16 is controlled.

When the print button 45 is pressed, the print button 45 outputs an operation signal indicating printing of a report or the like to the control unit 17. When the print button 45 is pressed, the control unit 17 controls to output the ultrasonic image and the diagnostic support information (graph, report) to the printer (not shown) as information representing the screen. Here, the information representing the screen is an image file capable of efficiently storing data, including, for example, JPEG (Joint Photographic Experts Group), GIF (Graphics Interchange Format), TIFF (Tagged Image File Format), and the like. When the report save button 46 is pressed, the report save button 46 outputs an operation signal indicating that the report is saved to the control unit 17.

When the non-display button 49 is pressed, the non-display button 49 outputs an operation signal indicating non-display of a report or the like to the control unit 17. The control unit 17 controls the display unit 16 so as to hide the diagnostic support information (graph, report) when the hide button 49 is pressed.

Next, an operation example of the ultrasonic diagnostic imaging apparatus 100 will be described with reference to FIG. FIG. 4 is a flowchart showing an operation example of the ultrasonic diagnostic imaging apparatus 100. The process of step S100 is started when the user selects an ultrasonic image from the image storage memory and activates the measurement function for the ultrasonic image.

First, the control unit 17 measures the size of the measurement site of the foetation displayed on the ultrasonic image based on the positions of the determined start point cursor 35 and end point cursor 36 (step S100). Then, the control unit 17 stores the size of the measurement site (for example, the BPD of the foetation) in the storage unit 15 as a measurement value.

Next, the control unit 17 controls the display unit 16 so as to display the diagnosis support information (step S110). For example, the control unit 17 simultaneously displays an ultrasonic image on the display area 22 of the inspection screen 20, a graph on the display area 24 of the inspection screen 20, and a report on the display area 26 of the inspection screen 20 without superimposing them on each other. Controls the display unit 16.

Next, the control unit 17 determines whether or not the measured value of the graph or the report has been corrected by the user via the operation input unit 11, for example (step S120). When the measured value is corrected (step S120: YES), the process proceeds to step S130. If the measured value is not modified (step S120: NO), the process transitions to step S140.

In step S130, the control unit 17 changes the measured value of the graph or the report.

In step S140, the ultrasound image and diagnostic support information (graphs and reports) are stored / printed. Specifically, when the save button 48 is pressed by the user via the operation input unit 11, the control unit 17 displays the ultrasonic image and the diagnostic support information displayed on the same screen without superimposing them on the screen. It is stored in the storage unit 15 as information to be represented. As a result, the ultrasonic image and the diagnostic support information as one screen are stored without being superimposed on each other. Further, when the print button 45 is pressed by the user via the operation input unit 11, the control unit 17 uses the ultrasonic image and the diagnostic support information displayed on the same screen without overlapping each other as information representing the screen. Control the printer (not shown) to print. As a result, the ultrasonic image and the diagnostic support information as one screen are printed without being superimposed on each other. After that, the process shown in FIG. 4 ends.

According to the ultrasonic image diagnostic apparatus 100 of the above embodiment, the display unit 16 and the ultrasonic image used for the measurement are acquired, and the diagnostic support information for supporting the diagnosis based on the measurement result is acquired, and the ultrasonic wave is obtained. A control unit 17 that controls the display unit 16 so that the ultrasonic image and the diagnosis support information are displayed on the same screen during the measurement using the image is provided. As a result, the diagnostic support information can be displayed without the user performing the screen transition input operation, so that the burden on the user can be reduced and the screen transition input operation is not required. Since the inspection time is shortened, the inspection efficiency can be improved. In addition, the ultrasonic image and the diagnostic support information can be compared and viewed. This makes it possible to improve the quality of inspection results. Further, when the test target is a human being (patient), the burden on the patient can be reduced by improving the test efficiency.

Further, according to the above embodiment, the measured value of the BPD displayed in the display areas 24 and 26 of the graph or report can be modified. As a result, the measured values can be corrected in the display areas 24 and 26 other than the display area 22 of the ultrasonic image, so that the workability can be improved. Further, since the position of the measurement cursor moves according to the correction of the measured value, it is possible to improve the workability in this respect as well.

Further, according to the above embodiment, the ultrasonic image and the diagnostic support information (graph and report) are displayed in the display areas 22, 24, and 26, respectively, which do not overlap with each other. As a result, the entire ultrasonic image and the diagnostic support information can be visually recognized at the same time, so that the quality of the inspection result can be further improved.

Further, according to the above embodiment, the ultrasonic image and the diagnosis support information as one screen without being superimposed on each other are stored in the storage unit 15. This can save storage space.

Further, according to the above embodiment, the ultrasonic image and the diagnostic support information as one screen are printed without being superimposed on each other. As a result, the recording medium (for example, paper) can be saved.

Further, according to the above embodiment, since the measured value is displayed on the report screen, it is possible to eliminate the need to display the measured value in the display area 22 of the ultrasonic image. Moreover, since the past measured values are displayed as a report, it is possible to visually recognize the past measured values. It is possible to check the growth process on the inspection screen.

<Modification example 1>
Next, a modification 1 of the display of the inspection screen 20 will be described with reference to FIG. FIG. 5 is a diagram showing a display example of the inspection screen 20.

The control unit 17 controls the display unit 16 so that the graph is displayed in the display area 24 of the inspection screen 20 when the following four conditions are satisfied.
Condition 1: The reference number of weeks of pregnancy is stored in the storage unit 15. Condition 2: The reference number of weeks of pregnancy is within a predetermined range (for example, the range from 0 to 45 weeks) Condition 3 : The graph is stored in the storage unit 15. Condition 4: The measured value is not less than the upper limit value of the graph and more than the lower limit value (it is possible to plot the measured value on the graph).

When at least one of the above four conditions is not satisfied, in other words, when the information for plotting on the graph is insufficient, the control unit 17 does not display the graph and determines the predetermined value shown in FIG. The display unit 16 is controlled so that the input dialog screen 27 is displayed in the display area 24 of the inspection screen 20.

The input dialog screen 27 is provided with input boxes 28 and 29 for receiving input of insufficient information. In the input boxes 28 and 29, GA is input by the user via the operation input unit 11. The input GA values (for example, 20w0d) are displayed in the input boxes 28 and 29. The control unit 17 displays the graph in the display area 24 of the inspection screen 20 when the above four conditions are satisfied by inputting the missing information, in other words, when the information for plotting on the graph is supplemented. The display unit 16 is controlled so as to be displayed on the screen.

According to the above modification 1, if the predetermined condition is satisfied, the graph is displayed in the display area 24 of the inspection screen 20, and if the predetermined condition is not satisfied, the graph is not displayed and instead, the input is input. The dialog screen 27 is displayed. Then, when insufficient information is input via the input dialog screen 27, a graph is displayed. This makes it possible to fill in the missing information for plotting on the graph with a simple operation.

<Modification 2>
Next, a modification 2 of the display of the inspection screen 20 will be described with reference to FIG. FIG. 6 is a diagram showing a display example of the inspection screen 20. In the second modification, the case where the diagnostic support information is enlarged and displayed will be described, but a graph will be given as an example of the diagnostic support information.

When the diagnosis support information (for example, the graph shown in FIG. 3) is displayed in the display area 24 of the inspection screen 20, the control unit 17 selects the display area 24 via the operation input unit 11 by the user. (For example, when the cursor 42 is located in the display area 24 and is clicked), the display unit 16 is controlled so as to enlarge and display the diagnosis support information. For example, the control unit 17 controls the display unit 16 so as to magnify and display the diagnosis support information (for example, the graph shown in FIG. 6) in the display area 22 of the inspection screen 20. At the same time, the control unit 17 controls the display unit 16 so as to reduce the ultrasonic image in the display area 24.

When the diagnosis support information (for example, the graph shown in FIG. 6) is displayed in the display area 22 of the inspection screen 20, the control unit 17 controls the control unit 17 when the close button 41 is pressed by the user via the operation input unit 11. Or, when an area other than the display area 24 is selected, the display unit 16 is controlled so that the diagnosis support information is displayed in the display area 24 in the original size before being enlarged and displayed. At the same time, the control unit 17 controls the display unit 16 so that the ultrasonic image is displayed in the display area 22 in the original size before being reduced and displayed.

When the user moves the diagnosis support information via the operation input unit 11 (for example, when the diagnosis support information is dragged and dropped), the control unit 17 enlarges and displays the diagnosis support information in the movement destination display area. The display unit 16 is controlled so as to.

When the ultrasonic diagnostic imaging apparatus 100 includes a touch panel (not shown) that outputs a position signal indicating a position pressed by the user to the control unit 17, the control unit 17 is located at a position away from the pressed position. The display unit 16 is controlled so as to enlarge and display the diagnosis support information.

According to the above modification 2, since the diagnosis support information (for example, a graph) is enlarged and displayed, the visibility of the diagnosis support information is improved. In addition, the diagnostic support information can be returned to the original display with a simple operation. In addition, the user can specify the place where the diagnostic support information is enlarged and displayed (the destination of the diagnostic support information). Further, when the touch panel is pressed, the diagnostic support information is enlarged and displayed at a position away from the pressed position. As a result, the diagnostic support information can be displayed while avoiding the part hidden by the finger (the finger that presses the touch panel), which is effective when the diagnostic support information is surely visually recognized by a simple operation of pressing the touch panel. Is.

<Modification example 3>
Next, with reference to FIG. 7, a modification 3 of the display of the inspection screen 20 will be described. FIG. 7 is a diagram showing a display example of the inspection screen 20.

The control unit 17 changes the display position of the diagnosis support information when the operation of changing the display position of the diagnosis support information is performed. Specifically, the control unit 17 changes the layout of the diagnosis support information when the user performs an operation of selecting and moving the diagnosis support information via the operation input unit 11. Specifically, as shown in FIG. 7, the control unit 17 changes the graph display area 24 to the lower left position of the inspection screen 20 in response to the movement operation of the diagnosis support information, and changes the report display area 26 to the lower left position. The display unit 16 is controlled so as to change to the lower right position of the inspection screen 20 and change the display area 22 of the ultrasonic image to the position on the center of the inspection screen 20. When the area 25 as shown in FIG. 7 is generated as a result of the layout change, for example, the control unit 17 controls the display unit 16 so as to display information useful for diagnosis in the area 25.

The control unit 17 controls the display unit 16 so as not to display the diagnosis support information when the user performs an operation of hiding the diagnosis support information (graph, report) via the operation input unit 11.

The control unit 17 controls the display unit 16 so as to display a thumbnail image (for example, a past ultrasonic image) instead of the diagnosis support information in the area where the diagnosis support information is displayed.

The control unit 17 controls the display unit 16 so as to display a medical image (for example, MRI) other than the ultrasonic image in place of the diagnosis support information in the area where the diagnosis support information is displayed.

According to the above modification 3, since the diagnostic support information (graph or report) can be selectively hidden, the display or non-display of the diagnostic support information can be arbitrarily changed according to the user's preference. Is possible. Moreover, since the thumbnail image is displayed, it is possible to confirm the growth process. Moreover, since a medical image other than the ultrasonic image is displayed, the quality of the examination result can be further improved.

<Modification example 4>
Next, with reference to FIG. 8, a modification 4 of the display of the inspection screen 20 will be described. FIG. 8 is a diagram showing a display example of the inspection screen 20.

When the user selects the diagnostic support information display areas 24 and 26 via the operation input unit 11, the control unit 17 has a pull-down menu 43 (transition shown in FIG. 8) indicating an output mode that can be selected for the diagnostic support information. The display unit 16 is controlled so as to display (print, save, output, edit, enlargement, etc.). For example, when the transition in the menu is selected, the transition to the past diagnosis support information is performed. If printing is selected, the diagnostic support information is printed. When saving is selected, the diagnostic support information is stored in the storage unit 15. Further, when the output is selected, the diagnostic support information is output to the external storage device. When editing is selected, the diagnostic support information can be edited. If enlargement is selected, the diagnostic support information is enlarged and displayed.
