Rotated Image VOI

A rotated Volume Of Interest can be defined interactively with XF.Interactive.DefineRotatedImageVOI. A new image can then be created (cropped) using Lucid.Core.CropRotatedImageVOI.

It is also possible to automatically create a RotatedImageVOI object from a processing task types. Examples of this are:

• Lucid.Util.RotatedImageVOIFromRegistrationPoints

• Lucid.Core.MomentOfInertiaTensor

Alternatively, one can think of the RotatedImageVOI object as a transformation matrix to rotate, translate, and scale the pixels in an image.

The following JSON Schema specifies the structure of a RotatedImageVOI object:
