3D modeling of the vessels from X-ray angiography

초록

Coronary artery diseases are usually revealed using X-ray angiographies. Such images are complex to analyze because they provide a 2D projection of a 3D object. Medical diagnosis suffers from inter- and intra-clinician variability. Therefore, reliable software for the 3D modeling of the coronary tree is strongly desired. This paper focuses on the automatic 3D modeling of the vessels from X-ray angiography. Our approach is based on a 3D model of standard vessels. The model is projected because it is difficult to suitably transform standard into individual vessels on 3D space. The modeling process is carried out in two steps. The first step consists of selecting automatically two sets of corresponding control points between standard and individual vessels. In the second step, 3D model of individual vessels is performed by warping with corresponding control points. Accurate descriptions of 3D model would be useful for quantitative diagnosis of atherosclerosis, for surgical or treatment planning, for monitoring disease progress or remission, and for comparing efficacies of treatments. © Springer-Verlag Berlin Heidelberg 2007.
