The registration of preoperative 3D to intraoperative 2D images plays a crucial role in percutaneous coronary intervention. This technique reduces uncertainty regarding vessel topology and depth information in 2D intraoperative images. The aim of 2D/3D image registration is to determine the most appropriate image alignment. However, 2D/3D registration of heart images is challenging, due to differences...
A method for registering preoperative coronary CTA with intraoperative monoplane X-ray angiography images is proposed to improve image guidance during minimally invasive coronary interventions. The method uses a patient-specific dynamic coronary model, which is derived from the CTA scan by centerline extraction and motion estimation. The dynamic coronary model is...
