ABSTRACT:
Apparatus and method for performing dual-energy x-ray imaging using two-dimensional detectors. The apparatus consists of, in physical order, an x-ray source, a front two-dimensional x-ray detector, a beam selector, and a rear two-dimensional x-ray detector. The subject is located between the x-ray source and front detector. The beam selector prevents primary x-rays from reaching selected locations of the rear detector. A pair of primary dual-energy images is obtained at the rear detector. Using a dual-energy data decomposition method, a low-resolution primary x-ray front detector image is calculated, from which a high-resolution primary dual-energy image pair is calculated. In addition, the data decomposition method can be used to calculate a pair of high-spatial-resolution material composition images.
