Abstract

This paper describes a method for automated assessment of the movement of the aorta from CT images using a new formulation of the active contour model to segment and track the aortic boundary and its movements through the temporal image sequence. The active contour model is capable of exploiting prior knowledge and posterior information of the image content, e.g. the anatomical shape of the aorta and the image gradient intensity of the aortic boundaries as well as physical constraint such as continuity of motion along the time dimension.
