摘要： The radiation three-dimensional position detector of the present invention comprises a scintillator unit (10), a light receiving element (20) and an operation section (30). The scintillator unit is disposed on the light incident plane of the light receiving element, wherein the scintillator unit is comprised of four layers of scintillator arrays, each layer being composed of scintillator cells arrayed in 8 row −8 column matrix. The scintillator cell produces scintillation light corresponding to the radiation absorbed thereby. The optical characteristic of a partition material for separating neighboring scintillator cells, which faces at least one same side face is different between a scintillator cell Ck1,m,n included in one scintillator array layer (k1-th layer) and a scintillator cell Ck2,m,n included in the other scintillator array layer (k2-th layer).

摘要： A depth of interaction detector with uniform pulse-height comprises a multi-layer scintillator obtained by coupling at least two scintillator cells on a plane and then stacking the planar coupled scintillator cells, in layers, up to at least two stages and a light-receiving element connected to the bottom face of each scintillator cell of this multi-layer scintillator, wherein the detector is provided with a means for discriminating the position of a scintillator cell, which receives radiant rays and emits light rays and a means for making, uniform, the quantity of the light emitted from each scintillator cell and received by the light-receiving element. The detector can provide precise detection information even when radiation is absorbed by and emitted from a scintillator layer positioned above the scintillator layer optically coupled to the light-receiving element, permits the production of a depth of interaction detector having a three-dimensional depth of interaction-detecting function and can provide the same total output signal, which is independent of the position or a specific scintillator cell practically emitting light if the radiation energy is identical.

摘要： A three-dimensional position-sensitive radiation detector is provided which has a three-dimensional array of photodetectors disposed on the surface of a scintillator block and which is capable of three-dimensionally identifying the position of light emission at which radiation has been detected within the detector. The three-dimensional position-sensitive radiation detector includes: a scintillator block including a central portion which restricts the direction of diffusion of light so as to direct the light in three axial directions and which has an optically discontinuous region, and an outer portion which is disposed on the outside of the central portion and which does not restrict the direction of diffusion of light; and photodetectors disposed on at least two outer circumferential surfaces of the scintillator block. The detector identifies three-dimensionally the position of light emission, thereby preventing deterioration in position discrimination performance even when inner scintillator elements are smaller than the photodetectors.
