本研究旨在评估一种光学相干断层扫描（OCT）和冠状动脉造影自动共配准的新方法。使用冠状动脉造影和OCT的管腔直径和侧支来创建2个特征集。随后，对特征集进行两步共配准方法，以匹配血管造影中心线上的每个OCT横截面。为了验证，鉴定了直径≥1.0 mm的所有侧分支，并将其作为配对的信托标志。地理误差定义为自动配准与真配对地标之间的距离。总共分析了181例患者的212条血管。1530个参考标志中有64个出现冠状动脉造影与OCT不匹配。中位地理误差为0.32（四分位间距为0.00-0.56）mm，共配准平均时间为20.69±1.07秒。综上所述，使用单一标准血管造影环路进行OCT和血管造影的快速自动共配准是可行和准确的。
This study sought to evaluate a novel approach for automatic coregistration of optical coherence tomography (OCT) and coronary angiography. Lumen diameters and side branches from both coronary angiography and OCT were used to create 2 feature sets. Subsequently, a 2-step coregistration approach was performed on the feature sets for matching of each OCT cross section on the angiographic centerline. For validation, all side branches with ≥1.0 mm diameter were identified and used as paired fiduciary landmarks. Geographical error was defined as the distance between the automatically coregistered and the true-paired landmarks. Altogether 212 vessels from 181 patients were analyzed. Mismatch of coronary angiography and OCT occurred in 64 of 1,530 reference landmarks. Median geographical error was 0.32 (interquartile range: 0.00-0.56) mm. The mean time for coregistration was 20.69 ± 1.07 seconds. In conclusion, fast and automatic coregistration of OCT and angiography using a single standard angiographic loop is feasible and accurate.
