ABSTRACT:
A hybrid imaging detector is for detecting ionizing radiation such as X-rays or electron radiation, or other ionizing radiation. The detector has a sensor (10) on a read-out chip (20). The sensor (10) includes a plurality of sensor material layers (12,14) of different materials stacked on top of one another, having differing radiation absorbing properties. The materials may be Si and SiGe, Si and Ge, or Si and amorphous Se, for example. The read-out chip is a photon-counting read-out chip that records a single count when it detects a pulse above a threshold.
