3D elastic registration of vessel lumen from IVUS data on biplane angiography

Abstract

Accurate reconstructions of vessels are important in the understanding of blood flow anomalies. We present a new elastic registration method to reconstruct the lumen of the femoral artery by fusion of Intravascular Ultrasound data and biplane angiography. The catheter path and pullback parameters are found by minimizing width discrepancy in the back-projections without the need for explicit catheter segmentation. Preliminary results on real subjects are promising and show the convergence of the algorithm. © Springer-Verlag Berlin Heidelberg 2003.
