Length of the vessels (\(l_{LAD} , \;l_{LCX} ,\; l_{RCA} )\) was measured by CAG. The lengths of LAD, LCX, and RCA are indicated in red, green, and blue, respectively. The cut-off diameter was 1 mm. LAD, left anterior descending artery; LCX, left circumflex artery; RCA, right coronary artery. a Arterial trees on coronary X-ray angiography (CAG). b The cut-off diameter of vessel-length measurement for OCT-FFR simulation. c The lengths of LAD, LCX, and RCA
