| 英文摘要 | The monolithic scintillation crystal detector has the ability to position the three-dimension interaction location in the detector depending on accurate acquisition of scintillation light distribution. Depth estimation of light field can be array in light field technology. A new detector model was designed in the paper which introduced a lens array for position in the monolithic detector. The scintillation light is focused by each lens unit in the lens array. Photons in some discrete p counter array where the scintillation light is focus on are detected to form an image of multiple focus points instead of the distribution detection based on continuous crystal. The position of the scintillation light source in the crystal can be recon focus image through optical path inversion. The detector model consisting of a monolithic crystal, a lens array and a mult counter was established in the paper. The monolithic scintillator was a lutetium-yttrium silicate (LYSO) scintillator with d mm×48 mm×45 mm. The lens was hemispherical with a radius of 15 mm supposed to be uniformly distributed in 3×3 arr was as same as the crystal. The crystal and the lens array were considered as a whole in the simulation. The multi-pixel p set at 44.4 mm from the crystal surface. The pixel size of the photon counter array was 3 mm and the quantum efficiency of symmetry of the three parts was same. The reconstruction algorithm was based on optical path inversion from multiple locating the 3D position of gamma-ray interaction. The intersection points of the inverted optical paths and the set z plane depths in the crystal was calculated in the reconstruction process. When the intersection points converged towards the sa plane, the depth of interaction was z0 and the intersection point in the z0 plane was the interaction point. The reconstructio analyzed to evaluate the performance of the monolithic scintillation crystal detector based on the lens array. The x/y resol 1.54 mm and the z resolution is better than 3.13 mm. The two interaction points when coincidence occurs are reconstruce that the energy is the same. The detector is feasible for the positioning of two interaction points by the reconstruction resu of selected positions. The monolithic scintillation detector based on a lens array has both good positioning ability and pos detector is suitable for the position reconstruction of multiple interaction points. © 2024 Atomic Energy Press.
