ABSTRACT:
An x-ray detector element suitable for use in computer tomography has a semi-insulating semiconductor body composed of a compound semiconductor, and is operated with a constant voltage source so that it functions as an x-ray-sensitive photoconductor. A measurement instrument is connected across the voltage source for detecting the photocurrent, which is indicative of the x-rays incident on the semiconductor body.
