Abstract

A three-dimensional/four-dimensional (3D/4D) imaging apparatus and a region of interest (ROI) adjustment method and device are provided. An ROI is adjusted through an E image in a 3D/4D imaging mode, in which the E image is refreshed in real time when the ROI is adjusted and has a scan line range larger than that of the ROI.

Claims

1. A method for adjusting region of interest (ROI) in three-dimensional/four-dimensional (3D/4D) imaging, comprising:

obtaining an E image by emitting ultrasonic waves, wherein the E image comprises a reduced data size B-mode image;

adjusting, using a processor, a scan line range of the ROI through the E image in a 3D/4D imaging mode, wherein the E image has a scan line range larger than that of the ROI and smaller than or equal to that of a full frame, and wherein the scan line range comprises a distance from a beginning point to an ending point substantially along a direction of propagation of the ultrasonic wave.

2. The method of claim 1, wherein adjusting the ROI through the E image comprises:

in static 3D imaging, determining a scan angle, scanning the E image at the position of the scan angle, and adjusting the ROI through the E image.

3. The method of claim 1, wherein adjusting the ROI through the E image comprises:

in 4D imaging, scanning a frame of E image in scanning of each set of volume data, and adjusting the ROI through the E image.

4. The method of claim 1, wherein adjusting the ROI through the E image comprises:

in 4D imaging, determining a scan angle, scanning the E image at the position of the scan angle, and adjusting the ROI through the E image.

5. The method of claim 1, wherein the E image has a scan depth larger than that of the ROI.

6. The method of claim 1, wherein images displayed in the 3D/4D imaging mode comprise one or more of a 3D/4D image, a section image, and an E image.

7. A device for adjusting a region of interest (ROI) in three-dimensional/four-dimensional (3D/4D) imaging, comprising an ROI adjustment module configured to adjust a scan line range of the ROI through an E image in a 3D/4D imaging mode, wherein the E image has a scan line range larger than that of the ROI and smaller than or equal to that of a full frame, and wherein the scan line range comprises a distance from a beginning point to an ending point substantially along a direction of propagation of an ultrasonic wave used to obtain the E image.

8. The device of claim 7, wherein the ROI adjustment module adjusts the ROI in the following manner:

in static 3D imaging, determining a scan angle, scanning the E image at the position of the scan angle, and adjusting the ROI through the E image.

9. The device of claim 7, wherein the ROI adjustment module adjusts the ROI in the following manner:

in 4D imaging, scanning a frame of E image in scanning of each volume data, and adjusting the ROI through the E image.

10. The device according to claim 7, wherein the ROI adjustment module adjusts the ROI in the following manner:

in 4D imaging, determining a scan angle, scanning the E image at the position of the scan angle, and adjusting the ROI through the E image.

11. The device of claim 7, wherein the E image has a scan depth larger than that of the ROI.

12. A three-dimensional/four-dimensional (3D/4D) imaging apparatus, comprising a device for adjusting region of interest (ROI) in three-dimensional/four-dimensional (3D/4D) imaging, wherein the device comprises an ROI adjustment module configured to adjust a scan line range of the ROI through an E image in a 3D/4D imaging mode, wherein the E image has a scan line range larger than that of the ROI and smaller than or equal to that of a full frame, and wherein the scan line range comprises a distance from a beginning point to an ending point substantially along a direction of propagation of an ultrasonic wave used to obtain the E image.
