CMOS X-ray imagers are gaining importance in the field of small area X-ray imaging. The paper gives a comparison of CMOS and a-Si flat panel imagers for X-ray imaging applications. Advantages of the CMOS imagers include the higher readout speed and lower noise due to the much higher electrical charge mobility in crystalline versus amorphous silicon. The lower noise provides a wider dynamic range in CMOS even when the total pixel storage capacitance is the same as in a-Si. Also, because the… CONTINUE READING
