title: [A new method for infering vessel structure based on circle detection and Gabor filter].
abstract: To automatically infer the patterns of vessel structure such as the distal ends, segments, bifurvessel structures, and crossing of two vessels in X-ray angiographic images, a novel method is presented based on Gabor filter and circle detector. The method can cope with varying vessel curvature and intensity feature occur along the longitudinal vessel direction. The present study can facilitate 2-D quantitative description of vessel tree and 3-D vessel reconstruction, and provide an elementary clue for the diagnostics. The proposed method has been successively applied to both synthetic images for validation purposes and the actual angiographic images, which yielded encouraging results.
