Abstract
A method and system for displaying quantitative segmental data in a 4D presentation along with local deformation is disclosed herewith. The method comprises: identifying a segment in a volumetric image data. Then, the following steps are iterated to produce a four-dimensional rendering. The iterated steps include: tracking the segment of the volumetric image data to produce a displacement field. Local deformation of the segment is identified using the displacement field. And the segment is rendered with reference to the displacement field and the local deformation.

A method of displaying quantitative segmental data in a four-dimensional presentation of an object, comprising:
- identifying a segment in a volumetric image data;
- repeating the following steps a plurality of times:
- tracking the segment of the volumetric image data to produce a displacement field;
- identifying local deformation of the segment based on the displacement field;
- and
- rendering the segment with reference to the displacement field and the local deformation.
A method of improving visual perception of cardiac segmental deformation display in a three dimensional rendering, comprising:
- obtaining a volumetric cardiac image;
- defining at least one segment on the volumetric cardiac image based on a reference;
- and
- repeating the following steps a plurality of times:
- estimating a displacement field by tracking the segment to identify motion of the segment;
- identifying local deformation of the segment from the displacement field;
- rendering the segment with reference to the displacement field;
- and
