STONE PHANTOM DEVICE FOR LITHOTRIPSY QUALITY ASSURANCE

本工作的目的是开发一种新颖的集成石幻影 该设备将监测和显示幻石的状况， 用体外震波碎石术将其粉碎成粉末 系统 石幻影装置会显示 一个给定的能量所需的石头粉碎，从而测试 碎石机的冲击波发生、聚焦和结石定位 子系统，以及操作员的对准技能。 它将有助于 碎石治疗的重大进展， 碎石系统可靠性，提高操作者熟练度，优化 整体治疗效率，并了解 治疗参数和结石破坏。 根据我们的初步研究， 该项目的第一阶段将侧重于：1）开发一种可靠的 监测幻石的方法; 2）调查几种仿石 材料; 3）改进石头约束方法; 4）开发 使系统与冲击波放电同步的可靠方法。 在第二阶段全面开发后，石幻影装置将 为测量和评估提供了新的标准参考， 碎石系统，适用于临床质量保证，操作者 培训以及碎石系统内部和内部比较。

The purpose of this work is to develop a novel integrated Stone Phantom Device, which would monitor and display the condition of a phantom stone as it is crushed to a powder by an Extracorporeal Shock Wave Lithotripsy system. The Stone Phantom Device will display the number of shock waves of a given energy necessary for stone comminution, thereby testing the lithotripter's shock wave generating, focussing, and stone localizing subsystems, and also the operator's alignment skills. It will contribute to significant advances in lithotripsy treatment, in terms of increasing lithotripsy system reliability, improving operator proficiency, optimizing overall treatment efficiency, and understanding the relationships between treatment parameters and stone destruction. Based on our initial research, the Phase I portion of the project will focus on: 1) developing a reliable way to monitor the phantom stone; 2) investigating several stone-mimicking materials; 3) refining the method of stone constraint; and 4) developing reliable methods for synchronizing the system with shock wave discharges. When fully developed under Phase II, the Stone Phantom Device will represent a new standard reference for the measurement and evaluation of lithotripsy systems, applicable to clinical quality assurance, operator training, and lithotripsy system intra- and inter-comparison.
