The purpose of this investigation is to measure, characterize and report stray photon leakage and scatter radiation measurements from the Mobetron, an intraoperative electron linear accelerator designed for use in an operating room environment. The study is needed due to recent changes to the shielding design of the Mobetron, and also to provide specific information that may be required by regulation in various jurisdictions. An analysis is performed on a number of manufactured units to deter-mine an average 3D stray photon radiation map. This information provides a basis for determining patient-based load restrictions and/or additional shielding for the operating room. The data presented evaluates the number of procedures for which the Mobetron may be safely operated in a typical unshielded operating room.
本研究的目的是测量、描述和报告 Mobetron 术中电子直线加速器的杂散光泄漏和散射辐射测量值，该加速器专为在手术室环境中使用而设计。由于 Mobetron 的屏蔽设计最近发生了变化，因此需要进行这项研究，并且还需要提供各种司法管辖区可能需要的具体信息。对多个制造单元进行分析以确定平均 3D 杂散光辐射图。该信息为确定基于患者的负载限制和/或手术室的额外屏蔽提供了依据。所呈现的数据评估了 Mobetron 可在典型无屏蔽手术室中安全运行的手术数量。
