Chapter 42: Analyzing 3D-Mode images

Sculpting mode Description

Scalpel (Outside)

Scalpel (Outside) mode functions like a cookie cutter, much the same way as

Scalpel (Inside). Select a depth, then outline an area outside of which to remove

data.

To scalpel outside a 3D image:

1. Under Mode, click Scalpel (Outside).

2. Under Depth, set the slider to the required depth.

3. Trackball over the image.

4. Drag to create the outline of the area to be scalpeled.

5. Release the trackball button.

Data outside the outlined area is removed from the image.

Creating 3D volume measurements

In Cube view, the 3D-Mode Volume tool accurately measures object volumes

within an image. Volumes are created by segmenting a series of contours and

calculating the volume within the contoured region.

You can create 3D volumes in 3D-Mode, Power 3D-Mode, and Contrast 3D-Mode

using Parallel or Rotational Segmentation.

Typically, rotational segmentation should be used when the volume resembles a

spherical shape. Otherwise, use parallel segmentation.

For parallel segmentation, the system can perform manual, semi-automated or

automated segmentation of the volume. Rotational segmentation does not

support manual segmentation.

 When you segment the volume manually (in parallel segmentation only) you

manually draw each contour of the volume.

 When you segment the volume semi-automatically the system draws multiple

contours.

 When you segment the volume automatically the system draws multiple

contours.
