Abstract
We propose a novel method for nonrigid registration of whole coronary artery sequence models with periodic displacement field. 2D nonrigid registration method is proposed that periodic deformed information is applied into correspondence with whole fluoroscopic angiograms. The proposed methodology is divided into two parts: one cycle's nonrigid registration, spreading periodic displacement information into other cycles. In the first part, a nonrigid registration method of one cycle is implemented and used to compensate for any local shape discrepancy. In the second part, periodic displacement field is spreading into images on other cycles in order to align the whole sequence. Experimental evaluation conducted on a set of 9 fluoroscopic angiograms results in a reduced target registration error, which showed the effectiveness of the proposed methodology.
