摘　　要：目的 :针对现有临床移动DR曝光控制距离短、潜在放射性威胁等问题,设计一种面向床边摄影的改进型无线移动DR。方法:在不改变移动DR内部电路情况下,外置增加无线遥控曝光装置,通过对电源的远程无线开关实现远距离的影像曝光控制。无线遥控曝光装置由Wi-Fi控制模块、继电器控制电路及触点开关控制3个部分组成,可通过手机或计算机无线连接该装置,远程对曝光控制电路模块的电源进行控制,继而实现DR曝光控制。结果:该装置有效提升了移动DR的曝光控制距离,曝光成功率达100%,大大降低了医护人员每次临床检查时遭受的辐射剂量。结论:该装置为医护人员的床边摄影作业提供了高安全性保护,也可以高频率应用于无铅屏蔽防护环境下的放射作业场景。Objective To design an improved wireless mobile DR for bedside photography to solve the existing problems in short exposure control distance and potential radioactive threats. Methods A remote wireless exposure device was added without changing the internal circuit of the mobile DR, which realized remote image exposure control by remote switching of the power source. The device was composed of three components of Wi-Fi control module, relay control circuit and contact switch control, which was connected with a cell phone or computer by wireless means to control the power source of the exposure control circuit module and then to implement DR exposure control. Results The device increased the exposure control distance of mobile DR, had the success rate of exposure being 100%, and decreased the radiation dose to the medical staffs greatly. Conclusion The device enhances the safety of the medical staffs during bedside photography, and can also be applied to radiation operation in the scene of lead -free shielded protection environment with high frequency.
