冠状动脉三维重建是心血管力学中不可或缺的一部分，同时可为医生直观确定病变位置、病变程度提供便利。基于图像融合的冠状动脉三维重建能将两种图像的优点结合起来，为医生和研究人员提供血管三维走向、血管形态及斑块形态等信息。本文概括了近年来基于图像融合的冠状动脉三维重建方法，包括血管内超声(intravenous ultrasound, IVUS)与冠状动脉造影（coronary arteriography, CAG）图像融合、光学相干断层扫描技术（optical coherence tomography, OCT）与CAG图像融合、计算机断层扫描血管造影(computed tomography arteriography, CTA）与IVUS或OCT图像融合的三维重建方法，并阐述了各方法在临床以及力学计算研究中的应用现状。
