摘要
Signal measurements with diagnostic quality X rays have been performed on photosensitive diodes fabricated from hydrogenated amorphous silicon. Such diodes exhibit high light collection and conversion efficiency and excellent radiation damage resistance and thus are candidates for x-ray imaging. Results of an examination of the linearity of the output signal with respect to x-ray exposure rate and of the signal size normalized to exposure rate are reported for various x-ray energies and phosphor screens. Such photodiodes are presently being incorporated into two-dimensional arrays of addressable sensors for real-time medical imaging.
