Imaging of the coronary arteries is usually performed by X-ray contrast angiography or intravascular ultrasound (IVUS). Angiography provides information about the vessel lumen and its geometry. IVUS offers more detailed information that also includes the vascular wall. The chapter describes these two imaging modalities and their geometrically correct fusion yielding a 3-D and/or 4-D representation of the coronary geometry and morphology. The image-derived information is used for assessment of coronary function and plaque severity, blood flow related indices are determined using computational fluid dynamics. Detailed description of the methodology is followed by validation and clinical studies.
冠状动脉成像通常通过X射线造影血管造影术或血管内超声（IVUS）进行。血管造影术提供有关血管腔及其几何形状的信息。IVUS提供更详细的信息，还包括血管壁。本章描述了这两种成像方式及其几何上正确的融合，从而产生冠状动脉几何形状和形态的三维和/或四维表示。图像衍生的信息用于评估冠状动脉功能和斑块严重程度，使用计算流体动力学确定与血流相关的指标。在对该方法进行详细描述之后是验证和临床研究。
