The x-ray imaging system's requirements for CCD pixel

摘要

CCD technology has kept developing since CCD was invented and has very wide application in all kinds of imaging field. In the fields of security checking, non-destructive testing, and industry detection, CCD makes it possible that the digital radiography appears and accelerates the x-ray imaging performance improvement. So in this paper, CCD technology was introduce and its development was analyzed, then how it affect the x-ray imaging performance was conducted through the mathematical theory was model, which includes the pixel size and the pixel amount although the cooling condition is very important. This paper can be valuable and referential for designing an x-ray imaging system and it is the same for other kinds of imaging systems.
