X-ray image sensor

摘要

An x-ray image sensor has a matrix of radiation-sensitive detector elements, the detector elements being connected in two groups to a common read-out line on which bipolar signals are generated. Read-out signals of one polarity cause read-out of one of the groups of detector elements and read-out signals of the other polarity cause read-out of the other group. An image detector having high resolution but low technical outlay is thereby achieved.
