Coronary heart disease has become one of the main threats of human health. And coronary angiography is taken as the ldquogold standardrdquo for the assessment of coronary artery disease. But sometimes, the images are difficult to interpret visually because of the crossing and overlapping of the vessels in the angiogram. Three-dimensional (3D) representation of coronary arterial tree topology facilitates...
Three-dimensional reconstruction of vessels from digital X-ray angiographic images is a powerful technique that compensates for limitations in angiography. It can provide physicians with the ability to accurately inspect the complex arterial network and to quantitatively assess disease induced vascular alterations in three dimensions. In this paper, both the projection principle of single view angiography...
An automatic algorithm is proposed for centerline extraction of coronary arterial tree (CAT) in X-ray projections (coronary angiography). First of all, a segmentation algorithm based on Hessian matrix is applied for the extraction of CAT, followed by thinning the extracted CAT to obtain the skeletons. By applying centerline correction algorithm based on Gabor filter to the skeleton, the centerline,...
