Summary

Fluoroscopy is traditionally used for guidance of endovascular aortic repair (EVAR). In order to minimize exposure to radiation and nephrotoxic contrast medium, it is possible to generate a navigation road map by registering the intraoperative images with preoperative computed tomography angiograph (CTA). In modern hybrid operating rooms, several commercial solutions for this exists today (e.g. Siemens Syngo iPilot, Phillips Vesselnavigator). In order to register (fuse) the preoperative and intraoperative imaging to each other, a registration algorithm has to be applied. Sufficient accuracy of this algorithm is crucial, for if it fails the road map cannot be used for intraoperative navigation. The purpose of this study is therefore to evaluate two different 3D registration algorithms with regard to registration accuracy.
