Minimally Invasive Surgical Planning and Training System

描述(由申请人提供)： 该项目的目标是开发一种用于腹腔镜肝脏手术和消融术的交互式图像引导手术(IIGS)系统。该系统将允许临床医生使用手术中使用计算机断层扫描(CT)或磁共振(MR)成像获得的术前体积图像作为导航指导手段。 影像引导手术的有效性已经在神经外科中得到了证明。然而，这项技术在外科其他领域的应用一直很缓慢。在这个项目中，我们计划通过开发一种内窥镜系统来测量微创手术中器官的形状和变形，以解决主要的技术障碍之一。所得数据将用于患者和图像坐标系的联合配准，并用于驱动可变形组织模型。第二阶段的工作将通过在克里尔和范德比尔特大学进行的一系列体模和实验动物测试来评估。

DESCRIPTION (provided by applicant): The goal of this project is development of an interactive, image-guided surgery (IIGS) system for use in laparoscopic liver surgery and ablation. This system will permit clinicians to use preoperative volumetric images obtained using computed tomography (CT) or magnetic resonance (MR) imaging during surgery as a means of navigational guidance. The efficacy of image-guided surgery has been demonstrated in neurosurgery. However, application of the technology to other fields of surgery has been slow. During this project, we plan to address one of the primary technical barriers by developing an endoscopic system for measurement of the shape and deformation of organs during minimally invasive surgery. The resulting data will be used for coregistration of patient and image coordinate systems and to drive deformable tissue models. The Phase II work will be evaluated using a series of phantom and experimental animal tests performed at Creare and Vanderbilt University.
