Abstract

Segmentation and quanti cation of AAAs in CTA images is a relevant task for primary diagnosis and follow-up after EVAR. This paper describes and evaluates a re ned version of a fast and accurate method for the segmentation of the aneurysm thrombus based on a radial model approach. It uses a priori knowledge and spatial coherency for obtaining an initial thrombus contour which is then re ned by removing spurious sectors. The method provides a fast segmentation and easy parameter setup while maintaining a high degree of accuracy, which makes it suitable for clinical routine. Thrombus segmentation results are presented in real clinical CTA images used for EVAR follow-up which demonstrate the high speed and accuracy of the method.
