In order to improve the detection accuracy, it is often necessary to acquire a 3D image and a 4D image corresponding to the same detected tissue respectively. In the prior art, for the same detection tissue, if the 3D scanning mode and the 4D scanning mode need to be switched, the following steps are required: m1, the current mode is a 3D/4D scanning mode, and the user assists in clicking an operation button to exit the current 3D/4D scanning mode; m2, the user assists to click another operation button to enter a Pre-4D/3D mode (namely, the user returns to a main interface operated by the user), adjust the ROI box and adjust scanning parameters; m3, user-assisted clicking on a further operating button to re-enter the 4D/3D scanning mode.
In this prior art, it is necessary to return to the Pre-4D/3D mode to readjust the ROI box and scan parameters; however, in the scanning process of repeatedly switching under different scanning modes corresponding to the same tissue to be detected, due to the fact that the ROI frame and the scanning parameters need to be repeatedly adjusted, the probability that the direction position of the probe changes along with excessive operation of a user is high, meanwhile, in the scanning mode switching process, the probe needs to be repeatedly started and stopped, the probability that the probe is damaged is high, and the use efficiency of the probe is reduced.
