We present a new clinically practical method for online co-registration of 3D quantitative coronary angiography (QCA) and intravascular ultrasound (IVUS) or optical coherence tomography (OCT). The workflow is based on two modified commercially available software packages. Reconstruction steps are explained and compared to previously available methods. The feasibility for different clinical scenarios is illustrated. The co-registration appears accurate, robust and induced a minimal delay on the normal cath lab activities. This new method is based on the 3D angiographic reconstruction of the catheter path and does not require operator's identification of landmarks to establish the image synchronization.
我们提出了一种新的临床实用方法，用于三维定量冠状动脉造影（QCA）与血管内超声（IVUS）或光学相干断层扫描（OCT）的在线联合配准。该工作流程基于两个经过修改的商用软件包。文中解释了重建步骤，并与先前可用的方法进行了比较。阐述了该方法在不同临床场景下的可行性。联合配准看起来准确、可靠，并且对正常的心导管实验室操作造成的延迟极小。这种新方法基于导管路径的三维血管造影重建，无需操作人员识别标志点来建立图像同步。
