Patent ID: 7622719

Claim:
A CMOS flat X-ray detector, comprising: a plurality of CMOS detector chips, mounted on a substrate with a butt joint; drive elements configured to drive detector element columns on a chip, the drive elements being provided on a first edge on each rectangular CMOS detector chip; read elements for line-by-line reading of detector elements, provided on a second edge at right angles to the first edge; and detector elements provided on third and fourth edges of the chip, wherein the CMOS detector chips are arranged like shingles on one another, with one section of one detector chip, on which detectors are arranged, being located above one section of an adjacent other detector chip, on which read elements are arranged, in such a manner that a closed sequence of detector elements is seen in a plan view of the detector, and an X-ray converter is arranged on the shingle-like arrangement, with filling material for matching to a horizontally planar lower face of the X-ray converter being provided between the X-ray converter and the chip.
