Automatic Online Layer Separation for Vessel Enhancement in X-ray Angiograms for Percutaneous Coronary Interventions

Percutaneous coronary intervention (PCI) is a minimally invasive procedure for patients with advanced coronary artery disease. In this procedure, a stent pre-mounted on a delivery catheter is advanced over a guide-wire and through a guiding catheter at the site of narrowing in a patient ’s coronary arteries. Once the lesion site is reached, the delivery balloon is inflated and the stent is deployed against the coronary wall, assuring optimal patency of the artery. As there is no direct eyesight on the target area, these procedures are commonly performed under image guidance using X-ray angiography (XA), where coronary arteries are visualized with X-ray contrast agent.
