Research on Techniques of Segmentation and Registration of DSA-CT Living Liver images

Abstract

虚拟肝脏手术计划系统能够提供可交互操作的平台,仿真模拟手术过程,从而有助于制定合理的个体化手术方案,可以降低损伤肝脏重要结构的危险,减少术后肝功能不全的发生率。 作为虚拟肝脏手术计划系统的组成部分,本文探索的是基于计算机断层扫描(ComputedTomography,CT)图像及数字减影血管造影(DigitalSubtractedAngiography,DSA)图像中的肝血管的分割配准问题。首先对CT图像的肝实质进行分割,再进一步分割出肝实质中的血管,且对DSA图像中的血管进行分割;然后,对CT血管进行三维重建,选取部分角度进行投影,将投影结果与DSA图像进行配准,并在配准结果中选取与DSA...Virtual liver surgery Planning System can provide a platform for inter-operation, Simulate surgical procedures, thereby contribute to the development of individualized reasonable surgical program. It can reduce the risk of injury of important structures of liver; can reduce the incidence of Postoperative liver function. As an integral part of Virtual liver surgery Planning System, the exploration...学位:工学硕士院系专业:信息科学与技术学院计算机科学系_计算机系统结构学号:2302006115242
