阅读说明：本技术 患者移动状态的检测方法、装置及系统 (Method, device and system for detecting movement state of patient ) 是由 苟天昌 闫浩 李金升 于 2019-09-27 设计创作，主要内容包括：一种患者移动状态的检测方法、装置及系统,获取患者在摆位完成初始的当前位置信息(即第一参考坐标信息),获取患者在放射治疗过程中的当前位置信息(即第一坐标信息)(201)；将第一参考坐标信息和第一坐标信息进行坐标转换后得到处于治疗床坐标系下的第二参考坐标信息和第二坐标信息(202)；根据第二坐标信息和第二参考坐标信息,对患者进行治疗管理(203)。在放射治疗的过程中,及时判断患者是否发生移动,即实现对患者移动的实时追踪。相应的,根据移动情况对患者进行可靠治疗管理,有效避免因患者发生移动而导致放射线照射到其他正常器官,造成其他正常器官被误照射而出现损伤的问题,放射治疗精度较高。(A method, a device and a system for detecting the moving state of a patient acquire the initial current position information (namely first reference coordinate information) of the patient after the patient is positioned, and acquire the current position information (namely first coordinate information) of the patient in the radiation treatment process (201); performing coordinate conversion on the first reference coordinate information and the first coordinate information to obtain second reference coordinate information and second coordinate information in a coordinate system of the treatment couch (202); and performing treatment management (203) on the patient according to the second coordinate information and the second reference coordinate information. In the process of radiotherapy, whether the patient moves or not is judged in time, and the movement of the patient is tracked in real time. Correspondingly, the reliable treatment management is carried out on the patient according to the moving condition, the problem that the other normal organs are damaged due to the fact that the other normal organs are irradiated by the radiation rays caused by the movement of the patient is effectively avoided, and the radiation treatment precision is high.)
