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.

描述（由申请人提供）： 本项目的目标是开发一种用于腹腔镜肝脏手术和消融的交互式图像引导手术（IIGS）系统。该系统将允许临床医生在手术期间使用通过计算机断层扫描（CT）或磁共振（MR）成像获得的术前体积图像作为导航引导手段。 影像引导手术的有效性已在神经外科得到证实。然而，该技术在其他外科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解决一个主要的技术障碍，该系统用于在微创手术中测量器官的形状和变形。所得数据将用于患者和图像坐标系的配准，并驱动可变形组织模型。将使用在Creare和范德比尔特大学进行的一系列体模和实验动物试验对II期工作进行评价。
