1. A CT detector-module for detecting X-rays comprising:
a matrix of photosensors, each of which generates signals responsive to photons incident thereon;
a scintillator mounted over the matrix that converts X-rays incident on the scintillator to photons to which the photosensors are sensitive;
an anti-scatter collimator mounted over the scintillator;
and electronic circuitry located in close proximity to the photosensors to which each of the photosensors is connected for processing the signals generated by the photosensors;
wherein parts of the module are formed from an absorbing material having a high X-ray absorption coefficient and shield the circuitry from radiation.
