Chapter 42: Analyzing 3D-Mode images
6. Select the preferred rotational segmentation parameters in the Segmentation
section of the Volume tool.
Set the desired Method of segmentation: Auto or Semi.
Set the Angle of rotation. The angle represents the degrees separating each
contour. The default value is 18 degrees.
Set the Direction of rotation: Clockwise or Counterclockwise, relative to
the axis of rotation.
If Semi was selected as the method of segmentation, select the Step Num
value. This specifies the number of contours the system creates.
7. Click Proceed to draw subsequent contours.
If you select the Method Auto the system creates a sufficient number of
contours to complete a full rotation around the volume. This completes the
segmentation procedure and the volume calculation is displayed in the
lower left corner of the cube view.
If you select the Method Semi the system creates the number of contours
specified in the Step Num setting. Repeat the previous steps until you
segment the full volume. Click Finish to complete the segmentation. The
volume calculation is displayed in the lower left corner of the cube view.
Parallel segmentation
f To create a volume using parallel segmentation:
1. While you analyze your 3D-Mode image, to view the 3D-Mode tools set in the
left panel:
