The invention provides a
detector for positive
electron emission
imaging equipment, and positive
electron emission
imaging equipment. The
detector is provided with an upper end surface and a lower endsurface, and includes multiple
layers of
detector modules arranged in a height direction up and down, wherein each layer of detector module includes a layer of
scintillation crystal module and a layer of photosensor array which is coupled by a plurality of photosensors in the length and width directions; the
scintillation crystal module is a
scintillation crystal array coupled by a plurality of
scintillation crystals in the length and width directions; the photosensor array is coupled to a lower end surface of the scintillation crystal module for detecting visible photons which are generatedduring the reaction process of light gamma photons and the scintillation crystal module; a layer of photosensor array is arranged between every two
layers of scintillation crystal arrays in the multiple
layers of detector modules arranged up and down; a scintillation crystal array is arranged between every two layers of photosensor arrays; and the gamma photons enters from the upper end surface, and the upper end surface is the upper surface of the scintillation crystal module located at the uppermost layer. The detector for positive
electron emission
imaging equipment has the advantages of high positioning capability for gamma photons, high
time resolution, high sensitivity, and
high spatial resolution.
