摘要： The present application relates to a dual-energy detection method, system and apparatus. The apparatus includes: a first pixel detector array proximal to a ray source, configured to detect ray source photons having relatively low energy; and a second pixel detector array distal from the ray source, configured to detect ray source photons having relatively high energy; wherein the first pixel detector array includes a plurality of rows of first pixel detectors, the first pixel detector including a first sensitive medium, a first photosensitive device, a first incidence plane, and a first window; the second pixel detector array includes a single row of second pixel detectors, the second pixel detector including a second sensitive medium, a second photosensitive device, a second incidence plane, and a second window; and each of the second pixel detectors has the same pixel area as corresponding plurality of first pixel detectors thereof.
