Abstract
Cardiac roadmapping consists in correctly overlaying a vessel map sequence derived from an angiogram acquisition onto a fluoroscopy sequence used during PTCA intervention. This enhanced fluoroscopy sequence however suffers from several drawbacks such as breathing motion, high noise level, and most of all suboptimal contrast-enhanced mask due to segmentation defaults. This invention proposes to reverse the process and to locally overlay the intervention device as seen in fluoroscopy onto an optimal contrast-enhanced image of a corresponding cycle. This drastically reduces or suppresses the breathing motion, it provides the high image quality standard of angiograms, and avoids segmentation defaults. This proposal could lead to a brand new navigation practice in PCI procedures.
