ABSTRACT:
An x-ray imaging detector having an x-ray converter layer, a pixellated detection array closely adjoining the x-ray converter layer, and a substrate supporting the detection array, the substrate having a surface nearest said x-ray converter layer, the substrate including one or more elements having atomic numbers greater than 22, said elements having a total concentration in the substrate of greater than about 1 mole percent relative to the total number of moles of elements having atomic numbers of 22 or less, the substrate having a thickness in the same direction as the thickness of the x-ray converter of less than about 0.2 mm.sup.2 divided by the thickness of the converter in millimeters, the substrate having a dimensionless absorption exponent of greater than about 0.5 and less than about 5 for gamma ray emission of Am.sup.241 at about 60 keV;
