Polychromic Digital Radiography Detector with Patterned Mask for Single-Exposure Energy-Sensitive X-Ray Imaging

摘要

A digital radiography system, having: a pixelated optical detector; and a mask positioned adjacent to the pixelated 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.
