Abstract

The purpose of this work is to investigate the potential image quality of scintillator/CCD-based direct digital medical x-ray imaging systems. The x-ray detector is composed of a scintillating screen to convert x-ray photons into lower energy radiation (UV/visible/NIR) that is then collected by a lens or a fiberoptic taper and converted to an electrical signal by a CCD. The DQE (on-axis geometry) was modeled by extending the analysis used for storage phosphor systems. The effect of various system parameters on the system DQE has been investigated. Two coupling approaches, an array of lenses, and an array of fiberoptic tapers, have been studied. For each coupling approach, two applications, chest radiography and mammography, were examined and the DQE was modeled to be comparable to screen/film systems.
