Ionizing radiation imaging device

摘要

The device has at least one planar detector (2a, 2b) able to transform a radiation (8) into electrical charges and a common electrode (12) on an input face and a mosaic of point electrodes (14) and metal bands (34a-34e) on an output face, several planar integrated circuit chips (10a, 10b) facing the input face of the detector and having a mosaic of reading circuits (16) and metal bands (30a, 30d) for connecting the circuits to external supply, control and processing devices for output signals, each reading circuit being hybridized by a microsphere to a point electrode and the bands of the chip being positioned facing bands of the detector and hybridized thereto by microspheres. The device is to be used in mamography or dental imaging.
