no. 1 Embodiment approach ）
[0038] First, the configuration of the ultrasonic diagnostic apparatus according to the first embodiment will be described. figure 1 It is a diagram for explaining a configuration example of the ultrasonic diagnostic apparatus according to the first embodiment. Such as figure 1 As shown, the ultrasonic diagnostic apparatus according to the first embodiment includes an ultrasonic probe 1 , a monitor 2 , an input device 3 , an acquisition device 4 , and an apparatus main body 10 .
[0039] The ultrasonic probe 1 has a plurality of piezoelectric vibrators that generate ultrasonic waves based on a drive signal supplied from a transmission unit 11 included in the device main body 10 described later. In addition, the ultrasonic probe 1 receives reflected waves from the subject P and converts them into electrical signals. In addition, the ultrasonic probe 1 has a matching layer provided on the piezoelectric vibrator, a backing material that prevents ultrasonic waves from propagatin...
no. 2 Embodiment approach ）
[0130] In the second embodiment, a case will be described in which a probe image group is generated from ultrasonic images taken in the past.
[0131] For example, in the second embodiment, the control unit 18 acquires three-dimensional position information through the input device 2 instead of the acquisition device 4 . That is, the control unit 18 acquires three-dimensional position information at the time of capturing the ultrasonic image based on the input information input by the observer who refers to the ultrasonic image previously generated by the image generating unit 15 via the input device 3 .
[0132] Figure 14 It is a figure for demonstrating 2nd Embodiment. To cite an example, through the control of the control unit 18, such as Figure 14 As shown, the monitor 2 displays a past ultrasonic image (past image) designated by the observer, and also displays a rendered image representing an imaging site of the past image designated by the observer. The observer ref...
no. 3 Embodiment approach ）
[0142] The third embodiment uses Figure 16A , Figure 16B as well as Figure 17 etc. for explanation. Figure 16A , Figure 16B as well as Figure 17 It is a figure for demonstrating 3rd Embodiment.
[0143] The control unit 18 according to the third embodiment displays the group of past ultrasound images and probe images of the subject P acquired from the image memory 17 in the first area of the display area of the monitor 2 . Specifically, when the operator designates the past test ID of the subject P, the control unit 18 acquires the composite image group of the designated test ID from the image memory 17 . Hereinafter, a past composite image group that is a composite image group of the specified inspection ID is referred to as a past image group.
[0144] For example, the set of past images taken is Figure 10 Exemplified are B-mode images along the past time series, rendered images representing imaging sites, and "a plurality of past image groups along time se...
