项目摘要

DESCRIPTION (provided by candidate): One of the basic tenants of Neurosurgical planning is the ability to generate an operative approach that minimizes the disruption of normal tissue while allowing the required exposure to target tissues. This tenet is pushed to an extreme when dealing with pediatric neurosurgical patients. To aid the surgeon in his or her ability to appreciate the location of target tissues as well as their relationship to normal tissues, graphical workstations have been developed. Such systems allow a surgeon to appreciate the position of the target tissues in relation to other normal tissues. The optimization of a surgical trajectory and the ability to guide a surgeon along that optimized trajectory has been the cornerstone of minimally invasive neurosurgical techniques. In order to register the real patient to the 3 dimensional computer model rigid fixation and dynamic referencing is usually required. These references are usually some form of cranial or spinal clamping system. For the pediatric population these devices are inappropriate. In our parent grant we proposed a new guidance system that utilized the design and fabrication of custom patient specific frames. These new frames are designed to mechanically register to the patient's anatomy and provide the required registration between the 3 dimensional model and the patient through surface fitting. The surgical trajectory is incorporated into the guide eliminating frames and operative tracking devices. These guides are fabricated using rapid prototyping technology. The development and testing of computer algorithms to enable this approach is the goal of the parent grant. Cranial and spinal procedures can now be planned and custom frames fabricated and brought to surgery. The design criteria for pediatric patients are, however, very different from that of adult patients. Every aspect of the procedure from imaging through operative positioning must be examined and optimized for the pediatric population. This proposal addresses the extension of this new technology, with the goal optimizing a system for pediatric neurosurgery.

描述（由候选人提供）：神经外科计划的基本租户之一是能够产生一种手术方法，以最大程度地减少正常组织的破坏，同时允许所需的暴露于目标组织。在与儿科神经外科患者打交道时，该宗旨被推到极端。为了帮助外科医生欣赏目标组织的位置及其与正常组织的关系的能力，已经开发了图形工作站。这样的系统允许外科医生欣赏与其他正常组织有关的靶组织的位置。手术轨迹的优化以及指导外科医生沿该优化轨迹的能力一直是微创神经外科技术的基石。为了将真实患者注册到3维计算机模型刚性固定和动态引用的3维患者。这些参考通常是某种形式的颅骨或脊柱夹紧系统。对于儿科人群，这些设备不合适。在我们的父母赠款中，我们提出了一种新的指导系统，该系统利用定制患者框架的设计和制造。这些新框架旨在机械地向患者的解剖结构注册，并通过表面拟合提供3维模型与患者之间所需的注册。手术轨迹纳入了导游，消除了框架和手术跟踪设备。这些指南是使用快速原型制造技术制造的。计算机算法启用这种方法的开发和测试是父母赠款的目标。现在可以计划颅和脊柱程序，并定制框架并进行手术。但是，小儿患者的设计标准与成年患者的设计标准大不相同。从成像到手术定位的过程的每个方面都必须针对小儿人群进行检查和优化。该建议旨在解决这项新技术的扩展，目标是优化小儿神经外科系统的系统。
