METHOD FOR ACQUIRING 3-DIMENSIONAL IMAGES OF CORONARY VESSELS, PARTICULARLY OF CORONARY VEINS

摘要

A method and an apparatus for acquiring 3-dimensional images of coronary vessels (11), particularly of coronary veins, is proposed. 2-dimensional X-ray images (13) are acquired within a same phase of a cardiac motion. Then, a 3- dimensional centerline model (15) is generated based on these 2-dimensional images. From 2-dimensional projections of the centerline model into respective projection planes, the local diameters (w) of the vessels in the projection plane can be derived. Having the diameters, a 3-dimensional hull model of the vessel system can be generated and, optionally, 4-dimensional information about the vessel movement can be derived.
