Objective To investigate the optimal beam tube potential for amorphous silicon/ cesium iodide flat panel digital chest radiography ( indirect DR). 目的探索碘化铯/非晶硅数字摄影系统(间接DR)拍摄胸片的适宜管电压。
The electron beams produced by the needle-shaped annular carbon fiber-coated cathode soaked with cesium iodide ( CsI) salt and annular stainless steel cathode were separately used to bombard the nylon targets. 分别用自制浸渍碘化铯(CsI)针式环状碳纤维阴极和环状不锈钢阴极所产生的电子束轰击尼龙目击靶,研究碳纤维阴极发射均匀性。
