DESCRIPTION (provided by applicant): This Phase I STTR application represents a partnership between a university-based research group (Imaging Science and Information Systems [ISIS] Center, Department of Radiology, Georgetown University) and a small business specializing in open-source software development (Kitware, Inc. of Clifton Park, NY). Over the past 1 1/2years, the ISIS Center has been developing a prototype image-guided surgery system called IGBiopsy to enhance the precision of instrument placement for minimally invasive abdominal interventions. This system incorporates a soon-to-be commercially available magnetic tracking system and specially designed needles whose tip position can be monitored. The software for this prototype is based on the Visualization Toolkit (VTK), an open-source software system developed and now supported by Kitware. This prototype software and hardware will be used as the starting point for the work proposed here. The specific aims are: 1. Integration. As a demonstration project, we will integrate the graphical user interface for image-guided abdominal interventions developed by Georgetown with the Insight Registration and Segmentation toolkit (ITK) developed by Kitware and others. 2. Pre-clinical evaluation. The software developed in Aim 1 will be evaluated in a pre-clinical study using a liver respiratory motion phantom already developed by Georgetown. The accuracy of the system in assisting the physician in placing a biopsy needle into a simulated liver lesion will be evaluated. These tests and Specific Aim 3 will also be used to evaluate the accuracy of the magnetic tracking hardware in the interventional suite. 3. Clinical evaluation. The system will be further evaluated using a cadaver study in the interventional suite. The accuracy of the system in assisting the physician in targeting selected points in the liver will be evaluated. If the Phase I work proposed here is successful, Kitware and Georgetown University will be in a position to develop an open-source software framework for image-guided surgery in a Phase II effort.

描述（由申请人提供）： 此I阶段的STTR应用程序代表了一个基于大学的研究小组（成像科学和信息系统[ISIS]中心，乔治敦大学放射学系）与专门从事开源软件开发（Kitware，Inc.的小型企业）之间的合作伙伴关系。纽约州克利夫顿公园）。在过去的1 1/2年中，ISIS中心一直在开发一种名为Igbiopsy的原型图像引导的手术系统，以增强仪器放置的精度，以减少腹部侵入性的腹部干预措施。该系统结合了即将成为市售的磁跟踪系统和特殊设计的针头，可以监视其尖端位置。该原型的软件基于可视化工具包（VTK），这是一个开源的软件系统，现在由Kitware开发和支持。该原型软件和硬件将用作这里提出的工作的起点。具体目的是： 1。集成。作为一个演示项目，我们将集成由乔治敦开发的图像引导的腹部干预措施的图形用户界面，以及由Kitware等开发的Insight注册和分割工具包（ITK）。 2。临床前评估。 AIM 1中开发的软件将在临床前研究中使用乔治敦已经开发的肝呼吸运动幻影进行评估。该系统在协助医师将活检针对模拟肝病变放置的精度进行评估。这些测试和特定目标3还将用于评估介入套件中磁跟踪硬件的准确性。 3。临床评估。该系统将使用介入套件中的尸体研究进一步评估。将评估系统协助医生靶向肝脏中选定点的准确性。 如果在这里提出的第一阶段工作是成功的，那么Kitware和Georgetown University将有能力在II期工作中开发用于图像引导的手术的开源软件框架。
