Fluoroscopy is a low dose imaging technique. As such, a very sensitive detector is required to create images of good quality. Present day flat panel active matrix read out systems introduce an amount of noise that inhibits present direct and indirect methods from producing optimal quality images at fluoroscopic exposure rates (0.1-10 microR per frame). The gain of the direct conversion approach using amorphous selenium (a-Se) was investigated to determine whether by increasing the applied… CONTINUE READING
