Three-dimensional reproduction of coronary vascular trees using the double-square-box method of tracking

The double-square-box method of tracking, in conjunction with spatial correlation techniques, is employed for accurate determination of the three-dimensional position of the vessel centerline, as well as the vessel size and contrast, from stereoscopic coronary arteriograms. In order to facilitate systematic identification and correlation of the vessel information in multiple images, we present a method with which the vessel segments in the vascular tree can be identified accurately in terms of their position in the hierarchical structure using the size, contrast, direction, and branching relationships of the vessels.
