Method and apparatus for evaluating a 3D image of a laterally-symmetric organ system
First Claim
1. A method for evaluating a three-dimensional image of a laterally-symmetric organ system, comprising the steps of:
- electronically segmenting a three-dimensional image of a laterally symmetric organ system, to obtain a segmented organ system;
electronically deforming said segment organ system to produce an electronically deformed organ system comprising two halves that are mirror-symmetrical with regard to their external shape;
electronically determining differences between said mirror-symmetric halves of the deformed organ system by comparing one of said halves with the other of said halves; and
visually representing the determined differences between said halves.

Abstract
In a method for automated evaluation of a three-dimensional map of a laterally-symmetric organ system as well as medical image acquisition system and a computer program for this purpose, a three-dimensional image of the organ system is segmented, and the segmented organ system is deformed such that the deformed organ system has two mirror-symmetric halves with regard to its external shape. The differences between both mirror-symmetrical halves of the deformed organ system are determined by a comparison of one half with the other half. Alternatively, instead of the deformation of the segmented organ system a mirror-symmetric normal model of the organ system can be deformed, relative to the organ system, or vice versa, such that differences of corresponding regions of both halves of the organ system can be determined using the normal model. The determined differences are presented to a user.
