How to Outline Objects Using Smart Brush



Steps

1.

Go to the region of interest using the Zoom, Scroll and Pan functions.

2.

Select Smart Brush.

3.

Highlight the areas to be segmented.

Trace an outline with a brush stroke, keeping it slightly inside the object. The voxel lines follow the contours of the object.The region that is outlined is determined by the gray values and the contrast of the image.

Smart Brush segments all connected pixels with similar gray values in the defined area.

Defining a larger area increases the potential gray value scale.

4.

If edges of the segmented area are not correctly separated from the surrounding area, use Erase to define these borders more accurately.

If a mouse is used, use the right mouse button to erase when Smart Brush is active.

5.

Scroll to next slice.

6.

Repeat the highlighting steps until the object has been created in all relevant slices.

Optionally, use 3D interpolation to outline the whole object volume.

7.

Verify the object.

8.

Select Done.
