Abstract

The invention provides a detector and a preparation method of the detector and an emission imaging device with the detector. The detector comprises a grid mold, a crystal layer and a solid photoconductive layer. The grid mold comprises multiple transverse walls, multiple longitudinal walls and a peripheral frame encircles the walls from side direction, wherein the transverse walls and the longitudinal walls are respectively arranged along the transverse direction and the longitudinal direction in an intersection mode so that multiple grid grooves which are arranged in a matrix mode are formed in the peripheral frame. The crystal layer comprises multiple scintillation crystals arranged in a matrix mode, wherein the multiple scintillation crystals and the multiple grid grooves are correspondingly fixed in the multiple grid grooves one by one, and the top surfaces of the multiple transverse walls and the multiple longitudinal walls are not lower than that of the crystal layer. The solid photoconductive layer is arranged on the top surface of the crystal layer and provided with a cutting groove, and the portions of the multiple transverse walls and the multiple longitudinal walls which are higher than the crystal layer are inserted into the cutting groove. The detector effectively controls the decoding errors of crystals and improves the resolution ratio of the image space of an emission imaging device.

Description

technical field [0001] The present invention relates to an emission imaging system, in particular to a detector for an emission imaging device and a manufacturing method thereof, and also to an emission imaging device with the detector. Background technique [0002] Emission imaging technologies such as Positron Emission Tomography (PET) and Single-Photon Emission Computed Tomography (SPECT) have been used in medical diagnosis, pathology research, pharmacology research, drug development and other fields. [0003] Taking positron emission imaging as an example, it uses the phenomenon that the positrons produced by the decay of positron isotopes and the negative electrons in the human body have an annihilation effect. The detector is used to detect the gamma photons produced by the annihilation effect to obtain the distribution information of isotopes in the human body, and the computer performs reconstruction and combination operations to obtain a three-dimensional tomograph...
