基于数字血管减影的无框架配准算法的实验研究

The Experimental Research on the Frameless Registration Based on the Digital Subtraction Angiography

我们在无框架立体定位算法的基础上,进行了脑部多模医学图像配准的临床实验研究。实验证明,本配准算法能准确地将数字血管减影(Digital subtraction angiography,DSA)图像中的血管信息融合进计算机体层成像(Computed tomography,CT)的解剖结构中,三维显示后方便医生进行诊断和手术计划,对于计算机辅助外科手术研究具有重要的临床医学价值。

In this paper, we present an experimental research on the frameless registration of DSA/CT images based on frameless localization algorithm. The result shows that, 3D fusion and registration of vessels in the DSA images and anatomical structures in CT images will help surgeons to make accurate diagnosis and on plann operative.
