Advanced software tools for planning the placement of skeletal fixation hardware

描述（由申请人提供）：物理科学公司及其在医学建模公司和布里格姆妇女医院的合作者提议开发规划颌面手术的软件。该软件将补充PSI正在开发的OsteoMark系统，并将与许多外科医生使用的当前手术计划流程集成。目前规划颌面手术的软件允许识别截骨和碎片的移动，但不允许容易地合并固定硬件或干扰物。钢板成型和螺钉放置是由少数供应商之一使用工程计算机辅助设计软件完成的。在这个项目中，我们将开发一套格式标准，用于描述来自几乎任何供应商的固定硬件的几何、运动和可变形性特征。我们将开发用于在虚拟模型上放置和弯曲固定板的软件工具，并将在来自多个供应商的板上测试算法。新的算法将允许快速评估来自不同供应商的许多钢板选择，从而为每位患者选择最佳方案。最初由计划人员使用，它将为临床医生提供更好的选择，减少计划时间，从而降低成本。随着治疗计划软件的发展，诸如此类的自动化功能将使临床医生能够在他们的办公桌上做更多的计划。更好地规划面部和骨骼其他部位的手术将减少时间和成本，改善美观和功能效果。

DESCRIPTION (provided by applicant): Physical Sciences Inc. and its collaborators at Medical Modeling Inc. and the Brigham and Women's hospital propose to develop software for planning maxillofacial surgery. The software will complement the OsteoMark system under development at PSI and will be integrated with the current surgical planning process used by many surgeons. Current software for planning maxillofacial procedures allows identification of osteotomies and movement of fragments but does not allow easy incorporation of fixation hardware or distractors. Plate shaping and screw placement are done by one of a few vendors using engineering computer-aided design software. In this program, we will develop a set of format standards that will describe the geometric, movement, and deformability characteristics for fixation hardware from virtually any vendor. We will develop software tools for placement and bending of fixation plates on a virtual model, and will test the algorithm on plates from multiple vendors. The new algorithms will allow rapid evaluation of many plate options from different vendors to select the best for each patient. Initially to be used by planners, it will provide clinicians with better options with less planning time and hence lower cost. As treatment planning software evolves, automated features such as these will make it possible for clinicians to do more planning at their desks. Better planning for surgery in the face and other parts of the skeleton will lead to reduced time and cost and improved aesthetic and functional outcomes.
