Selection of Rotation Steps
The "Rotation Steps" define, how many contours have to be generated. The decision, which
rotation step should be chosen depends on the shape of the ROI.
For example: An angle setting of [30˚] means that after the fist trace has been done, the
volume data set is rotated 30˚ and then the next trace has to be performed, and so on. With
rotation step [30˚], 6 traces have to be done.
6˚ = 30, 9˚ = 20, 15˚ = 12 and 30˚ = 6 traces
Selection of the Aspect Ratio (Zoom) The 3D image as well as the sectional image can be
varied by their aspect ratio, by turning the [Zoom] digipot.

This selection is only available, if generation Mode [Automatic - Sphere] is selected.
