Paper Abstract

Variation in the diameter of vessels is a key information for treatment of stenosis. This information is usually obtained from standard 2-D projective acquisitions. We propose an automatic method for the quantification of vessels cross- sections in 3D vascular reconstructions from x-ray images. First, a closed continuous surface is extracted. This surface represents the vessels contours selected with a given centerline. Then, the area of the cross-sections along the central axis is obtained by intersection of the contour and the plane of each cross-section. A model of the vessels allows to correct the first estimation. Tests on phantom images give a precision of the vessels radius below 0.5 voxel. Results are also presented on real vessels containing stenosis.
