- In this paper, we present a novel method for the real-time cardiac motion compensation. Our method generates interpolated car-diac motion using segmented mesh models from preoperative 3D+T computed tomography angiography (CTA). We propose a pair-wise mesh registration technique for building correspondence and interpolating the control points over a cardiac cycle. The key contribution of this work is a rapid creation of a deformation eld through a concise mathematical for-mulation while maintaining desired properties. These are C2 continuity, invertibility, incompressibility of cardiac structure and capability to handling large deformation. And we evaluated the proposed method using dierent conditions, such as deformation resolution, temporal sampling rates, and template model selection.
