Tracking heart surface features to determine myocardial contrast agent enrichment

Abstract Fluorescent cardiac imaging can be applied for intraoperative quality control after a coronary bypass grafting surgery to ensure the myocardial perfusion by evaluating increasing contrast agent enrichment in heart. The motion due beating heart impedes interpretation of vessels and leads noisy curves. We propose tracking surface features compensate thereby improve analysis enrichment. Furthermore, we vessel segmentation pipeline local evaluation directly vessels.
