传统的定量冠状动脉造影是在二维（2-D）投影视图上进行的。这些视图由血管造影师选择，以最大限度地减少血管重叠和透视缩短。在这种非标准化的情况下获得的2-D投影视图。然而，没有办法知道或估计在QCA过程中发生了多少误差。此外，冠状动脉具有曲线形状，并且由于它们附着于心肌而经历周期性变形。因此，有必要获得三维（3-D）信息，以最好地描述和量化人体冠状动脉的动态曲线性质。使用患者特定的3-D冠状动脉重建算法和常规血管造影图像，提出了一种新技术来描述：1）3-D冠状动脉和冠状动脉内器械的曲线性质; 2）冠状动脉内器械和心脏运动引起的动脉变形的幅度; 3）关于输送冠状动脉内器械的预期“路径”的最佳视图。
Traditional quantitative coronary angiography is performed on two-dimensional (2-D) projection views. These views are chosen by the angiographer to minimize vessel overlap and foreshortening. With 2-D projection views that are acquired in this nonstandardized. fashion, however, there is no way to know or estimate how much error occurs in the QCA process. Furthermore, coronary arteries possess a curvilinear shape and undergo a cyclical deformation due to their attachment to the myocardium. Therefore, it is necessary to obtain three-dimensional (3-D) information to best describe and quantify the dynamic curvilinear nature of the human coronary artery. Using a patient-specific 3-D coronary reconstruction algorithm and routine angiographic images, a new technique is proposed to describe: 1) the curvilinear nature of 3-D coronary arteries and intracoronary devices; 2) the magnitude of the arterial deformation caused by intracoronary devices and due to heart motion; and 3) optimal view(s) with respect to the desired "pathway" for delivering intracoronary devices.
