Data detailed in 'X-ray imaging using avalanche multiplication in amorphous selenium: investigation of intrinsic avalanche noise' have been presented. According to a study from Toronto, Canada, "The flat-panel detector (FPD) is the state-of-the-art detector for digital radiography. The FPD can acquire images in real-time, has superior spatial resolution, and is free of the problems of x-ray image intensifiers-veiling glare, pin-cushion and magnetic distortion."

"However, FPDs suffer from poor signal to noise ratio performance at typical fluoroscopic exposure rates where the quantum noise is reduced to the point that it becomes comparable to the fixed electronic noise....
