5.11.3.1 Basic Procedures for Static 3D Imaging
To perform static 3D imaging:
1. Select the proper probe and exam mode; make sure there is sufficient gel on the probe for
scanning.
2. Obtain a 2D image, and optimize the image if necessary.
The imaging conditions should be:
High contrast between the desired region and the AF (amniotic fluid) surrounded.
Clear boundary of the desired region.
Low noise of the AF area.
3. Press the user-defined <3D> key to enter Static 3D mode, and define the ROI and curved VOI.
Methods to adjust the ROI:
Under acquisition preparation status: Roll the trackball to change the ROI size, position and
curved VOI, press the right <Set> key to toggle among setting the ROI position, size or curved
VOI. Press the left <set> key to adjust VOI angle.
Tap [Flip VOI] to flip VOI. Tap [Reset VOI] to reset the angle of VOI to the original status.
Enter touch screen mapping mode. See Chapter 3.7.4 The Display of Touch Screen and Its
Operation for details.
Draw a circle on the desired area. Move ROI over the circle to adjust the size and position of
ROI. Roll the trackball or press <Set> to adjust ROI.
Move the cursor over the VOI, and move the cursor to the desired area to adjust the VOI
curve.
