摘　　要：冠状动脉树的三维信息对于心血管疾病的评价和诊断具有十分重要的意义。研究了基于两幅冠脉造影图像重建三维冠状动脉树的理论模型,首先根据透视投影原理建立一个双平面冠脉造影系统的投影模型。并分析两幅不同角度的造影图像之间的几何变换关系。然后提出一种新型的深度求解方法。最后给出冠状动脉树模型的三维重建结果。Three-dimensional information of coronary artery tree is important for diagnosis of coronary diseases, as well as for performance of catheter-based interventions. This paper is concerned with the 3D reconstruction of coronary artery tree from two biplane X-ray angiograms. We first establish a projection model of biplane X-ray angiographic system using theory of perspective projection, and analyze the geometrical transformation between two angiograms with different imaging angles. Then we present a novel depth-solving method. The theoretical model is evaluated by experiments of reconstruction using simulated coronary angiograms.
