Abstract :
This paper compares the pros and cons of CMOS imagers with a-Si flat panel imagers for digital X-ray imaging applications, including limitations imposed by the large area, low dose rate nature of medical X-ray imaging. The paper also highlights, which parameters of the CMOS technology need further improvements.
