Extraction of pulmonary vessels from MDCT thorax scans

Abstract

This paper considers problem of pulmonary vessels identification in MDCT thorax scans. Specifically, the method for vessels segmentation is proposed. The introduced method is 3D region growing approach were growth of the region is guided and constrained by results of random walk segmentation applied to consecutive CT slices. The main steps of the proposed approach are described. Results of vessel segmentation from exemplary MDCT datasets provided by the introduced method are presented and discussed.
