摘要：We present a tool for tracking coronary vessels in MRI
scans of the human heart to aid in the screening of heart
diseases. The vessels are identified through a single click inside
each vessel present in a standard orthogonal view. The vessel
identification results from a series of computational steps
including eigenvalue analysis of the Hessian of the MRI image
followed by a level set-based extraction of the vessel centerline.
All identified vessels are highlighted using a virtual contrast
agent and displayed simultaneously in a spherical curved
reformation view. In cases of over segmentation, the vessel traces
can be shortened by a click on each vessel end point. Intermediate
analysis results of the vessel computation steps can be displayed
as well. We successfully validated the tool on 40 MRI scans
demonstrating accuracy and significant time savings over manual
vessel tracing.
