Imaging measurement system with a printed photodetector array

摘要

Low cost large area photodetector arrays are provided. In a first embodiment, the photodetectors comprise an inorganic photoelectric conversion material formed in a single thick layer of material. In a second embodiment, the photodetectors comprise a lamination of several thin layers of an inorganic photoelectric conversion material, the combined thickness of which is large enough to absorb incoming x-rays with a high detector quantum efficiency. In a third embodiment, the photodetectors comprise a lamination of several layers of inorganic or organic photoelectric conversion material, wherein each layer has a composite scintillator coating.

1. An imaging system comprising:
a radiation source which rotates around a central z-axis of the imaging system to perform imaging scans; and an inorganic photodetector array including several discrete inorganic photodetectors arranged on a curved support, such that each row of inorganic photodetectors is aligned along the curve of the curved support, and each column of inorganic photodetectors is aligned in parallel to the central z-axis of the imaging system, wherein conductor paths are disposed along a distal surface of the curved support which is substantially opposite a surface of the support on which the inorganic photodetectors are disposed, and further comprising holes in the support filled with a conductor material different than the conductor path to electrically connect the conductor paths to the inorganic photodetectors, wherein the conductor paths associated with a column of inorganic photodetectors are located along the distal surface of the support opposite the column of inorganic photodetectors to a side of the inorganic photodetector array.
