FAST 3D PRE-SEGMENTATION OF ARTERIES IN COMPUTED TOMOGRAPHY ANGIOGRAMS

  • Chapter
Book cover Computer Vision and Graphics

Part of the book series: Computational Imaging and Vision ((CIVI,volume 32))

Abstract

A pre-segmentation algorithm for computed tomography angiograms (CTA) is described. It is based on adaptive thresholding. The median axis of the binarized image provides arterial centerlines and estimates of the local radii. Boundary location is refined by analyzing radial intensity profiles in the vicinity of their intersections with the thresholds. The thresholding rule was learned on CTAs of 60 patients. The method was successfully evaluated in 10 patients.
