Coronary angiography remains the gold standard for diagnosis of coronary
artery disease, the most common cause of death worldwide. While this procedure
is performed more than 2 million times annually, there remain few methods for
fast and accurate automated measurement of disease and localization of coronary
anatomy. Here, we present our solution to the Automatic Region-based Coronary
Artery Disease diagnostics using X-ray angiography images (ARCADE) challenge
held at MICCAI 2023. For the artery segmentation task, our three-stage approach
combines preprocessing and feature selection by classical computer vision to
enhance vessel contrast, followed by an ensemble model based on YOLOv8 to
propose possible vessel candidates by generating a vessel map. A final
segmentation is based on a logic-based approach to reconstruct the coronary
tree in a graph-based sorting method. Our entry to the ARCADE challenge placed
3rd overall. Using the official metric for evaluation, we achieved an F1 score
of 0.422 and 0.4289 on the validation and hold-out sets respectively.

我们提出了一种基于 X 射线血管造影图像的、能够自动化诊断冠状动脉疾病的自动区域冠状动脉疾病诊断的方法，该方法结合了经典计算机视觉的预处理和特征选择，通过增强血管对比度来提高血管分割的准确性，并利用 YOLOv8 生成血管图像并基于逻辑推理的方法重构冠状血管树以实现最终分割，我们在 ARCADE 挑战中获得了第三名，验证集和保留集的 F1 得分分别为 0.422 和 0.4289。
