Patent ID: 7010092

Claim:
An optically-coupled digital radiography system for simultaneously producing multiple images of differing energies of a subject from a single x-ray exposure of the subject, the system comprising: (a) a first scintillator that produces a visible first image when subjected to an x-ray exposure of a subject; (b) a first digital camera optically coupled to the first scintillator for capturing the first image; (c) an x-ray filter positioned in the path of the x-ray exposure and downstream of the first scintillator, for selectively attenuating a portion of the x-ray spectrum of the x-rays that have passed through the first scintillator, wherein the x-ray filter is coated with a reflective coating and is angled to reflect the first image from the first scintillator to the first camera; (d) a second scintillator positioned in the path of the x-ray exposure and downstream of the filter and that produces a visible second image when subjected to x-rays that have passed through the filter, the second image being different than the first image; and (e) a second digital camera optically coupled to the second scintillator for capturing the second image.
