5-34 Image Optimization
5.10.1 Overview
Only probes DE11-3E and SD8-1E support Static 3D imaging.
Ultrasound data based on three-dimensional imaging methods can be used to image any structure
where a view cannot be achieved with the standard 2D-mode and to improve the understanding of
complex structures.

Terms

3D image Volume Rendering (VR): the image displayed to represent the volume data.

4D: continuous-sweep volume acquisition.

View point: a position for viewing volume data/3D image.

MultiPlaner Rendering (MPR): the three sectional planes of the volume acquisition. As shown
in the figure below, the XY-paralleled plane is the C-section, the XZ-paralleled plane is the B-
section, and the YZ-paralleled plane is the A-section. The probe is moved along the X-axis.

ROI (Region of Interest): a volume box used to determine the height and width of scanning
volume.

VOI (Volume of Interest): a volume box used to display the 3D image (VR) by adjusting the
region of interest in MPR.

ROI and VOI
After the system enters 3D/4D imaging, a B image with ROI displays on the screen. A line (shown
in the following figure) shows that the upper edge position of the VOI is inside the ROI.
