    摘要： A detector assembly 100 is provided that includes a semiconductor detector 110, a pinhole collimator 130, and a processing unit 150. The semiconductor detector 110 has a first surface 112 and a second surface 114 opposed to each other. The first surface includes pixels, and the second surface includes a cathode electrode. The pinhole collimator 130 includes an array of pinhole openings corresponding to the pixels. Each pinhole opening is associated with a single pixel of the semiconductor detector, and the area of each pinhole opening is smaller than a corresponding area of the corresponding pixel. The processing unit 150 is operably coupled to the semiconductor detector 110 and configured to identify detected events within virtual sub-pixels distributed along a length and width of the semiconductor detector 110. Each pixel includes a plurality of corresponding virtual sub-pixels (as interpreted by the processing unit), wherein absorbed photons are counted as events in a corresponding virtual sub-pixel.

    摘要： A X-ray radiation detector is disclosed which has a dual-layer structure photoconductor layer. The dual-layer structure consists of a first photoconductor layer (12) comprising a plurality of photosensitive particles and of a second photoconductor layer (22) on the first photoconductor layer (12), comprising a plurality of crystals obtained by crystal-growing photosensitive material. At least some of the plurality of photosensitive particles of the first photoconductor layer (12) may fill gaps between the plurality of crystals of the second photoconductor layer (22). A method of manufacturing the radiation detector may include: forming a first photoconductor layer (12) by applying paste, including solvent mixed with a plurality of photosensitive particles, to a first substrate (11); forming a second photoconductor layer (22) by crystal-growing photosensitive material on a second substrate (25); pressing the crystal-grown second photoconductor layer (22) on the first photoconductor layer (12) that is applied to the first substrate (11) and removing the solvent in the first photoconductor layer (12) via a drying process.
