| Abstract: | Objective To explore the method and technique of using flatbed large C-arm machine for lowering the radiation doses received by the patients during the interventional(both diagnostic and therapeutic) procedures.Methods In this study,the radiation dose rates were recorded with the built-in radiation monitoring divice of the flatbed large C-arm machine.The distance between the water phantom,the bulb and the flat panel detector was changed in turn,and the exposure model employed was changed accordingly(differe... |
