We present a tool for tracking coronary vessels in MRIscans of the human heart to aid in the screening of heartdiseases. The vessels are identified through a single click insideeach vessel present in a standard orthogonal view. The vesselidentification results from a series of computational stepsincluding eigenvalue analysis of the Hessian of the MRI imagefollowed by a level set-based extraction of the vessel centerline.All identified vessels are highlighted using a virtual contrastagent and displayed simultaneously in a spherical curvedreformation view. In cases of over segmentation, the vessel tracescan be shortened by a click on each vessel end point. Intermediateanalysis results of the vessel computation steps can be displayedas well. We successfully validated the tool on 40 MRI scansdemonstrating accuracy and significant time savings over manualvessel tracing.
