Purpose In the spirit of overcoming the signal-to-noise limitations of active matrix, flat-panel imagers (AMFPIs) which employ array circuits based on a-Si:H thin-film transistors (TFTs), an empirical investigation of the noise properties of prototyp

Active matrix, flat-panel imagers (AMFPIs) suffer from decreased detective quantum efficiency under conditions of low dose per image frame (such as for digital breast tomosynthesis, fluoroscopy and cone-beam CT) due to low signal compared to the addi

The DQE performance of active matrix flat-panel imagers (AMFPIs) degrades under low dose conditions – such as those encountered in digital breast tomosynthesis where electronic additive noise becomes comparable to imaging signal. Compared to commer

For active matrix flat-panel imagers (AMFPIs), relatively high levels of additive noise compared to the average imaging signal per interacting x-ray limits DQE under conditions of low dose per frame – degrading imaging performance in applications s
