Pixelized detector assembly structure capable of improving spatial resolution

The utility model relates to the field of medical detectors, in particular to a pixelated detector assembly structure capable of improving spatial resolution. The pixelated detector assembly structure comprises a photoelectric sensor array assembly and a pixelated crystal array composed of pixelated crystal strips. The photoelectric sensor array assembly is formed by closely arranging a plurality of photoelectric sensors along the left-right direction; the number of the pixelated crystal strips is at least two. The width size of the light emitting surface of each pixelated crystal strip is half of the width size of the light sensing surface of the photoelectric sensor; according to the pixelated detector assembly structure, the crystal is bridged to the photoelectric sensor array assembly, the strict corresponding relation between the position of the pixelated crystal strip and the measurement calculation position on the photoelectric sensor is achieved, distortion of a scanned image is avoided, and follow-up
