Abstract

A model based multiresolution, image segmentation technique which makes use of the velocity field information in phase contrast magnetic resonance (MR) angiograms, and an a priori assumption that locally, blood vessels appear as line segments was implemented. The list structure of the resulting segmentation can be used efficiently in image analysis and processing. Within this segmentation, flow direction, vessel axis, diameter and velocity estimates can be made. The paper demonstrates its use in extracting vessels from patient data and in the calculation of pressure gradients in a model stenosis.
