METHOD AND APPARATUS FOR AUTOMATIC 4D CORONARY MODELING AND MOTION VECTOR FIELD ESTIMATION

摘要

A method for computer-aided four-dimensional (4D) modeling of an anatomical object comprises acquiring a set of three-dimensional (3D) models representi ng a plurality of static states of the object throughout a cycle. A 4D correspondency estimation is performed on the set of 3D models to determine which points of the 3D models most likely correspond to each other, wherein the 4D correspondency estimation includes one or more of (i) defining a reference phase, (ii) performing vessel-oriented correspondency estimation, and (iii) post-processing of 4D motion data. The method further comprises automatic 3D modeling with a front propagation algorithm.
