To report a novel 3D-printed device ("SH phantom") that is designed for routine accuracy check of the Gamma Knife Icon High Definition Motion Management (HDMM) system.
SH phantom was designed using tinkerCAD software and printed on a commercial 3D printer. We evaluated the SH phantom on our Gamma Knife Icon unit regarding its usability and accuracy for routine HDMM QA.
Single-axis and multiple-axis measurements validated the SH phantom design and implementation. An HDMM QA accuracy of 0.22 mm or better along single axis was found using SH phantom.
The SH phantom proved to be a quick and simple tool to use to perform the HDMM system QA. The SH phantom was tested successfully and adopted by us as part of monthly QA for the Gamma Knife Icon.
报告一种新型3D打印设备(“SH体模”),其设计用于伽玛刀Icon高清运动管理(HDMM)系统的常规精度检查。
使用TinkerCAD软件设计SH体模,并在商用3D打印机上打印。我们在伽玛刀Icon设备上评估了SH体模在常规HDMM质量保证方面的可用性和准确性。
单轴和多轴测量验证了SH体模的设计和实施。使用SH体模发现单轴HDMM质量保证精度为0.22毫米或更高。
SH体模被证明是用于执行HDMM系统质量保证的快速且简单的工具。SH体模测试成功,并被我们用作伽玛刀Icon每月质量保证的一部分。
