[0041] The application scenario of this embodiment is: the static 3D image and the E image are displayed at the same time, the two can be switched, and the probe only needs to swing once, that is, only one volume data is used for imaging.
[0042] Such as figure 2 As shown, the ROI adjustment process of this embodiment includes:
[0043] 1) Collect a volume of volume data according to ROI in imaging mode;
[0044] 2) Perform static 3D imaging;
[0045] 3) When the ROI needs to be adjusted, select the E image, the E image will be refreshed in real time, reset the ROI in the E image and confirm the re-imaging.
[0046] Such as Figure 3-a As shown, the scan control mode during imaging in this embodiment is:
[0047] In imaging mode, the system collects a volume of data according to the ROI, the probe swings from the Angle position of BeginAngle to the Angle position of EndAngle, and the front end presses Figure 3-a Scanning is performed in the manner shown, and the scan lin...

[0050] The application scenario targeted by this embodiment is: under 4D imaging, 4D images and E frames are simultaneously displayed, and both are refreshed in real time. In the 4D imaging mode, the probe swings back and forth, and collects a volume of data to form a 3D image every time it swings in one direction. Adding the time dimension, the 3D image is updated in real time in the window to form a 4D image.
[0051] Such as Figure 4-a As shown, in this embodiment, the probe swings back and forth, and the volume sequence is generated during the scanning process of the front end, and the system refreshes the imaging of the volume sequence, and the images that can be displayed in real time on the screen include: cross-sectional images, 3D images, and E images , the system provides the user with display of various layouts, and various layouts may include one of the images or any combination of the three images. In order to display E-images, 4D images and cross-sectional imag...

[0055] The application scenario of this embodiment is: under 4D, the user selects a 4D image or an E image frame for real-time refresh. In the 4D imaging mode, the probe swings back and forth, and collects a volume of data to form a 3D image every time it swings in one direction. Adding the time dimension, the 3D image is updated in real time in the window to form a 4D image.
[0056] Such as Figure 5 As shown, the process of adjusting ROI in this embodiment includes:
[0057] 1) In imaging mode, the system collects volume data according to ROI;
[0058] 2) Real-time 4D imaging, at this time, the front-end scanning method is as follows Figure 6-a As shown, that is, the probe swings back and forth and only scans the ROI frame. Under 4D real-time display, the E image is not the current window, and the user can choose to display or not display it. When it is displayed, it is frozen (not refreshed in real time), that is, if only imaging , the E image window may not be display...
