  FIG. 4 is a diagram illustrating an example of a screen of image data identified by a plurality of tabs displayed on the display unit 45 and designated tabs. In the tab display area 81 of the screen 80a, for example, three tabs 842, 843, 844 searched by the tab 841 and the search unit 43 are displayed. In the image display area 82, still B-mode image data 85 identified by, for example, a designated tab 842 among the tabs 841 to 844 displayed in the tab display area 81 is displayed.

  Thus, by specifying the tab 842 displayed in the tab display area 81, the B-mode image data 83 displayed in the image display area 82 of the screen 80 in FIG. 3 is identified by the specified tab 842. The mode image data 85 can be switched. Thereby, it is possible to easily select an imaging condition that enables generation of clearer image data than the B-mode image data 83 displayed on the screen 80 shown in FIG.

  Here, among the plurality of tabs 842 to 844 displayed in the tab display area 81 of the screen 80a shown in FIG. 4, the B-mode image data 85 identified by the tab 842 is the clearest and expected sharpness. In order to obtain clear image data in the same manner as the B-mode image data 85, an operation for switching the B-mode image data 83 displayed on the screen 80 in FIG.

The supplementary information included in the image information having the tab 842 related to the tab 842 is searched from the stored image information and output to the switching unit 60. It should be noted that the B mode image data 83 displayed on the screen 80 may be stopped by a freeze operation from the operation unit 52, and then an input relating the tab 841 and the tab 842 may be performed.

  The switching unit 60 switches the B mode image data 83 identified by the tab 841 displayed in the image display area 82 of the screen 80 based on information related to the tab 842. Based on the incidental information related to the tab 841 output from the tab creation unit 41 and the incidental information related to the tab 842 output from the search unit 43, the B-mode image data 83 is generated for generating this image data. The mode is switched to the B mode image data generated based on the imaging condition when the B mode image data 85 is generated from the imaging condition.

  Here, the image data identified by the tab 841 is the B-mode image data 83 displayed in real time, and the image data identified by the tab 842 is the B-mode image data 85 stored. The imaging conditions included in the supplementary information related to 842 are supplied to the imaging unit 20 to change the imaging conditions. The imaging unit 20 generates B-mode image data based on the imaging conditions supplied from the switching unit 60, and an image configured by the generated B-mode image data and incidental information updated to the imaging conditions supplied from the switching unit 60. The information is output to the display data generation unit 44. The display data generation unit 44 arranges a plurality of tabs in the tab area, and arranges the B-mode image data generated according to the changed imaging condition in the image area and outputs it to the display unit 45. The display unit 45 displays a plurality of tabs 841 to 844 and B-mode image data in which the imaging conditions are changed in real time (step S4 in FIG. 2).

  FIG. 5 is a diagram showing an example of a screen of a plurality of tabs and B-mode image data displayed on the display unit 45 by an input relating two tabs 841 and 842.

In the image display area 82, B-mode image data 83a in which the imaging condition identified by the tab 841 displayed in the tab display area 81 is changed is displayed in real time.

  As described above, the tab 841 displayed in real time in the image display area 82 by the input from the operation unit 52 relating the tab 841 and the tab 842 displayed in the tab display area 81 of the screen 80a shown in FIG. The identified unclear B-mode image data 83 can be switched to the clear B-mode image data 83a that is generated based on the imaging conditions associated with the tab 842. Accordingly, since an operation for switching the screen of the display unit 45 and inputting an imaging condition is not required, the imaging condition can be changed with a simple operation, and the labor required for the operation can be reduced.

  When it is determined that the B-mode image data 83a displayed in the image display area 82 of the screen 80b shown in FIG. 4 is useful for diagnosis and an input for saving is performed from the operation unit 52, the data storage unit 42 The mode image data 83a and accompanying information are stored.

The diagnostic apparatus 200 ends the operation (step S5 in FIG. 2).

  Next, referring to FIG. 1 to FIG. 10, the TIC data displayed on the display unit 45 is changed according to an input from the operation unit 52 that relates one tab for identifying the TIC data and the other tab. An example of an operation for switching to TIC data obtained by synthesizing TIC data identified by one tab and TIC data identified by the other tab based on an imaging condition related to the other tab will be described.

  For example, the contrast agent inspection of the subject P is performed a plurality of times. In order to perform this contrast examination, after inputting the imaging conditions including the generation mode of the TIC mode from the operation unit 52, when the first contrast examination start input is performed, the system control unit 70 Instruct the unit to perform a contrast examination. The imaging unit 20 generates B-mode image data from a reception signal obtained by driving the ultrasonic probe 10 and scanning the subject P with ultrasonic waves based on the imaging conditions supplied from the system control unit 70. The generated B-mode image data is output to the image display unit 40. The display unit 45 of the image display unit 40 displays the B mode image data generated by the imaging unit 20.

  Then, an input for setting a region of interest of the B-mode image data displayed on the display unit 45 from the operation unit 52 and a timer time for measuring the B-mode image data and collecting TIC data are performed. Next, when an input for operating the timer switch is performed after the contrast medium is administered to the subject P, the image processing unit 32 starts from the imaging unit 20 based on the timer time information supplied from the system control unit 70.

Then, the generated TIC data, timer time, examination time, position information indicating the region of interest, examination information including subject information, and imaging conditions are output to the tab creation unit 41.

  The tab creation unit 41 creates a tab for identifying the TIC data output from the image processing unit 32, and adds the created tab to the TIC data. Then, the image information composed of the TIC data and the incidental information including the tab, the inspection information, and the imaging condition is output to the display data generation unit 44. The display data generation unit 44 arranges tabs and TIC data included in the image information output from the tab creation unit 41 in predetermined areas and outputs them to the display unit 45. The display unit 45 displays tabs and TIC data.

  FIG. 6 is a diagram showing an example of a tab and TIC data screen displayed on the display unit 45 by the first contrast examination. Tabs 845 created by the tab creation unit 41 are displayed in the tab display area 81 of the screen 80c. In the image display area 82, TIC data 86 identified by the tab 845 displayed in the tab display area 81 is displayed.

  The TIC data 86 includes B-mode image data 87 and TIC data 861 to 863 representing changes in luminance of the regions of interest 871 to 873 set on the B-mode image data 87.

  Each TIC data 861 to 863 is graphed on two-dimensional coordinates in which the horizontal axis is the elapsed time since the timer is operated and the vertical axis is the luminance. The TIC data 861 represents a change in the luminance of the region of interest 871 in the timer time T1 from when the timer is activated by input from the operation unit 52 until 35 seconds elapse, for example, after 19 seconds elapses.
