1. A method for coronary artery detection in a 3D cardiac volume, comprising:
- segmenting at least one heart chamber in said volume;
generating an initial estimation of a coronary artery in said volume based on the segmented at least one heart chamber, the initial estimation of the coronary artery comprising a plurality of control points defining the coronary artery; and
detecting the coronary artery in said 3D cardiac volume by refining each of the control points in the initial estimation of the coronary artery based on local information to each of the control points in said volume.

Abstract
A method and system for coronary artery detection in 3D cardiac volumes is disclosed. The heart chambers are segmented in the cardiac volume, and an initial estimation of a coronary artery is generated based on the segmented heart chambers. The initial estimation of the coronary artery is then refined based on local information in the cardiac volume in order to detect the coronary artery in the cardiac volume. The detected coronary artery can be extended using 3D dynamic programming.
