As the uneven distribution of contrast agents and perspective projection principle X-ray, vasculatures in angiographic image are with low generally superposed other organic tissues; therefore, it is very difficult to identify vasculature quantitatively estimate blood flow directly from images. In this paper, we propose a fully automatic algorithm named adaptive geometrical vessel tracking (AGVT) for coronary artery identification X-ray angiograms. Initially, ridge enhancement (RE) obtained...
Seed point is prerequired condition for tracking based method extracting centerline or vascular structures from the angiogram. In this paper, a novel seed detection coronary artery segmentation proposed. Vessels on image are first enhanced according to distribution of Hessian eigenvalue in multiscale space; consequently, centerlines tubular vessels also enhanced. Ridge extracted as candidate point, which then refined its mathematical definition. The theoretical feasibility proven. Finally,...
In this paper, a novel method is developed for the 3-D reconstruction of coronary artery trees from two angiographic images. Due to rotational distortion and unpredictable motion imaging chain, commonly used pinhole camera model cannot obtain desirable vascular trees. Curvature Scale Space (CSS) approach find correspondence by choosing similar views between various obtained technique in one cardiac cycle. Therefore, study curve matching epipolar constraint are integrated calculate...
