Abstract
A method and system are for analyzing an anatomical structure of interest in 3D image data. In an embodiment, the method includes segmenting a first contour of the structure of interest in the 3D image data, the first contour defining a first segmented contour volume within the 3D image data; generating a first 2D pattern based on at least a portion of the surface of the first contour or based on at least a portion of the first segmented contour volume; performing a texture analysis on the first 2D pattern; and outputting a texture analysis information.

A method for analyzing an anatomical structure of interest in 3D image data, comprising:
- segmenting a first contour of the anatomical structure of interest in the 3D image data, wherein the first contour defines a first segmented contour volume within the 3D image data;
- generating a first 2D pattern by unfolding at least a portion of a surface of the first contour or by unfolding at least a portion of the first segmented contour volume;
- performing a texture analysis on the first 2D pattern;
- generating a plurality of further contours based on the first contour of the anatomical structure, wherein the plurality of further contours define a plurality of further segmented contour volumes within the 3D image data, and wherein a plurality of segmented peel volumes are each defined by two different contours among the first contour and the plurality of further contours;
- and
- outputting texture analysis information for analyzing the anatomical structure of interest in the 3D image data, the texture analysis information being based on the texture analysis.
