ABSTRACT Radiation therapy offers cures to cancer patients but also is prone to error. Although the radiation oncology society sets up strict quality assurance and safety procedures to prevent treatment errors, they are difficult to follow on every treatment due to time, labor cost and other constraints. Automation is highly desired to improve treatment safety. The millimeter-wave (mmWave), which has been broadly employed to detect the collision and prevent an accident before it happens, can penetrate the patient’s clothing, immobilization device and tabletop, detect patient’s position automatically. Multiple mmWave devices may be installed in the treatment room, verify setup and detect patient motion automatically when integrated with treatment control software. The low-cost mmWave can potentially eliminate many major treatment errors without increasing labor costs. The nonionizing mmWave can also monitor the patient’s motion continuously and detect any intrafraction motion during treatment delivery. To achieve this goal, we will perform a study to achieve the following specific aims (SAs) -- SA1: Develop mmWave algorithms that can measure the absolute distance to the patient surface, and SA2: To develop and validate the mmWave technology to monitor a patient’s movement and breathing during RT delivery.

抽象的 放射疗法可以治愈癌症患者，但也容易出错。尽管放射肿瘤学 社会建立了严格的质量保证和安全程序来防止治疗错误，但它们很难 由于时间、劳动力成本和其他限制，每次治疗都要跟进。非常需要自动化 提高治疗安全性。毫米波（mmWave）已被广泛用于检测 碰撞，防患于未然，可以穿透病人的衣服，固定住 设备和桌面，自动检测患者的位置。多个毫米波设备可以安装在 治疗室，验证设置并在与治疗集成时自动检测患者运动 控制软件。低成本毫米波有可能消除许多重大治疗错误，而无需 增加劳动力成本。非电离毫米波还可以连续监测患者的运动， 检测治疗期间的任何分次内运动。为了实现这一目标，我们将进行一项研究 实现以下具体目标 (SA) -- SA1：开发可以测量的毫米波算法 到患者表面的绝对距离，以及 SA2：开发和验证毫米波技术 在 RT 分娩过程中监测患者的运动和呼吸。
