Radiation hard silicon detectors for x-ray imaging

A detector system for x-ray imaging, said detector system comprising:

• a detector having a plurality of adjacent edge-on detector modules, wherein:
• each of said edge-on detector modules comprises a first edge that is adapted to be oriented towards an x-ray source and a front-side running essentially parallel to the direction of incoming x-rays, said front-side comprising at least one charge collecting electrode and routing traces connecting the at least one charge collecting electrode with front-end electronics;
• and
• at least a subset of said plurality of adjacent edge-on detector modules being pairwise arranged, front-side to front-side, whereby a front-side to front-side gap is defined between the front-sides of said pairwise arranged edge-on detector modules;
• and wherein
• each said pairwise arranged edge-on detector modules include an anti-scatter collimator arranged in the x-ray path between said x-ray source and said edge-on detector modules and overlapping said front-side to front-side gap, said anti-scatter collimator being arranged to protect the front-side surface of both detector modules in each said pairwise arranged edge-on detector module from damaging x-rays, and
• each pair of said pairwise arranged edge-on detector modules further include an anti-scatter foil located in said front-side to front-side gap between the front-sides of said pairwise arranged edge-on detector modules.
