| 摘 要： | 提出了一种基于冠状动脉中心线的CT冠状动脉血管造影(CTCA)和血管内超声(IVUS)融合的方法。该方法,首先从CTCA中提取冠状动脉中心线,并沿中心线提取其横截面;其次,对IVUS内膜和中-外膜进行半自动分割;再次,使用环形最大强度投影算法把CTCA和IVUS投影到二维空间中,并使用投影图像进行配准。最后,使用图形学方法把CTCA和IVUS融合在同一个三维空间中。融合CTCA和IVUS可以给医生诊断冠心病提供更多有用的信息。

| Abstract: | This paper proposes a fusion method of coronary computed tomography angiography (CTCA) and Intravascular Ultrasound (IVUS) based on coronary artery centerline. In our method, firstly, the centerline is extracted from CTCA, and cut-plane is extracted along centerline; secondly, luminal and media-adventitia contour is segmented in IVUS; thirdly, cylindrical maximal intensity projection method is used to map CTCA and IVUS into 2-dimensional, and then the projection image is used to register CTCA and IVUS; finally, CTCA and IVUS is fused in 3-dimensional. The fusion method of CTCA and IVUS can provide more useful information to assist doctors in the diagnosis of coronary artery disease. |
