Paper Abstract

A large area, flat panel detector is being investigated for digital radiological imaging (radiography and fluoroscopy). The detector consists of an x-ray sensitive photoconductor to interact with x-rays and convert the absorbed energy to electron-hole pairs. The released charge is collected and stored on pixel electrodes and subsequently is read out electronically with an active matrix, i.e. a two dimensional array of thin films transistors (TFTs). The basic properties of the detector based on the characteristics of the photoconductor, the active matrix and the external charge amplifiers are analyzed.
