Abstract:
Object 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.
