| 摘 要： | 在交互式的图像导航热疗手术中 ,需要对病灶目标进行非常精确的实时成像和定位。而现有的超声成像技术很难单独完成这个任务。本研究提出了一种用手术前MRI图像重建的三维图像与手术中的超声图像进行配准的方法 ,对肝部肿瘤热疗手术中的目标进行定位。其配准方法采用的是基于肝部血管和表皮等特征的遗传配准算法。

| Abstract: | In the interactive image-guided thermotherapy, we need th e real time image and location of the target tumor. But the current mono-modal imaging technique can not do it. We present a method to register a pre-operativ e 3D MRI volume to a set of intra-operative ultrasound images for the target lo calization of the liver tumor in the thermotherapy. The registration method is a genetic algorithm based on the features such as liver surface vessels and liver surface. |
