ABSTRACT:
A digital radiography system, having: a pixilated optical detector; and a mask positioned adjacent to the pixilated optical detector, the mask comprising a repeating pattern of first and second portions configured to pass different wavelengths of electromagnetic radiation therethrough such that a polychromic X-ray image can be taken using only a single X-ray exposure with a single imaging detector.
