Vessel Surface Reconstruction with a Tubular Deformable Model

The invention is a method for modeling a carotid or renal artery to measure stenosis from 3D angiographic data that may otherwise exhibit limited image resolution and contrast. The method reconstructs vessel surfaces from 3D angiographic data using a deformable model that employs a tubular coordinate system. Vertex merging is incorporated into the coordinate system to maintain even vertex spacing and to avoid problems of self-intersection of the surface. This method produces reconstructed surfaces that have a realistic smooth appearance and accurately represent vessel shape. The method allows for an objective evaluation of vessel shape and may improve the precision of shape measurements from 3D angiography.
