Abstract

Methods and systems for manually assisted definition of vascular features are described. In some embodiments, vascular centerlines identified by image analysis are divided into segments. Optionally, one or more candidate paths extending to the vascular root position along chains of segments are generated for each of a plurality of vascular endpoint. Selection of paths which correspond to anatomical paths of blood flow is optionally based on manual review. Optionally, paths are manually defined, for example, based on selection of a plurality of waypoints. Optionally, paths are edited by use of an active contour method that allows relative rough indication of corrections to be transformed into path changes that conform closely to the geometry of nearby vasculature.
