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.
ABSTRACT
Objective To discuss the application value of the mobile DR in large-scale physical examination. Methods Compared each 500 chest images that collected for the physical examination by the mobile DR, direct digital radiography(DR), then did another comparison about each 300 chest images of mobile DR and phnendoskiascope, recorded them by no displayed, displayed and limpid-displayed. Results The resolution of images collected by the mobile DR was comparative with the ones collected by direct digital radiography, better than phnendoskiascope in showing details. Conclusion The mobile DR images have a good resolution ratio as DR images have, meanwhile, this machine is easy to be taken and removed Examination while DR could not, and therefore the machine can do large-scale physical whatever inside or outside.
