5-46 Image Optimization
5.11.3 Static 3D
Static 3D provides single frame image acquisition of 3D images.During the scanning; the probe performs
the scanning automatically.
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
knob 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.
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.
