Abstract :
A method to reconstruct vessels from intravascular ultrasound (IVUS) image sequence and X-ray angiograms is proposed in this paper. The pullback path of IVUS catheter is tracked and reconstructed from angiographic image pair acquired during IVUS intervention. Cross-sectional borders of the vessel wall are detected from IVUS frames in a semiautomatic manner. After axial locations of IVUS frames are determined along the 3D pullback path of IVUS catheter, their spatial orientations are determined based on a Frenet-Serret frame model and global optimization. Finally, the vessel is accurately reconstructed with solid modeling technique. Experimental results with clinical data demonstrate the validity.
