Abstract
The utility model relates to a solid-state detector array architecture used in radiation imaging system, belonging to radiation detection technical field, comprising a plurality of scintillating crystals and photodiodes coupling with the crystals. The structural characteristics of the solid-state detector array architecture are: each scintillating crystal and photodiode are cemented, solidified, and coated with a reflecting layer to form a single detector. All detectors are put in order successively, insulated from each other by partitions, and solidified. The bottom of each photodiode is equipped with an insulator. Each partition and insulator are rabbeted on a metallic channel to form the detector array. Lead plate and sponge rubber layer are arranged on the detector array, contained in metallic cover, and fixed on a metallic channel slab. Compared with prior art, the utility model has the advantages of light protection, moisture resistance, vibration insulation, anti-electromagnetic interference, and convenient installation and maintenance; anti-scattering and anti-interference capabilities are also improved to greatly improve the definition of imaging.
Description
Technical field
The utility model belongs to the radiation checking technical field, relates to the solid probe device that is used for X, gamma-radiation imaging system,
Background technology
In the prior art, Chinese patent 02286053.3 discloses a kind of radiant image solid probe, the detector array of forming with it, though possessed detection efficiency and highly sensitive, anti-irradiation, anti-scattering, the anti-harassing and wrecking ability of electromagnetism, environmental suitability are strong, passage of scintillation light is harassed is advantage such as zero.But, because the sheathing material of single detector is to be formed and narrow space by the lower material extending of density, it in too thick heavy metal material can not be set, otherwise it is excessive to understand the dead band, thereby ray is harassed and is fallen thoroughly inadequately with scattering.
Summary of the invention
In order to solve above-mentioned problems of the prior art, the purpose of this utility model provides a kind of solid detector array architecture that is used for radiation image-forming system, it can keep solution lucifuge, protection against the tide, vibrationproof, the electromagnetism antijamming capability is strong, installation and maintenance are easily advantage the time, do not reducing the sensitive volume and do not increasing under the prerequisite in dead band, improve the anti-scattering of ray to greatest extent, resist the ability of harassing, improve the sharpness of imaging.
In order to reach above-mentioned goal of the invention, the technical solution of the utility model realizes as follows:
The solid detector array architecture that is used for radiation image-forming system, it comprises a plurality of scintillation crystals that formed by cesium iodide or cadmium tungstate and the photodiode of coupling with it.Its design feature is that described each scintillation crystal and the bonding curing of photodiode also scribble reflection horizon formation single detector.Each detector is arranged in order with dividing plate isolates and bonding curing mutually, and the bottom suit insulator of each photodiode also makes that its pin is downward to be gone out.Each dividing plate, insulator interlocking form the detector array of being made up of a plurality of detectors on the metal frid.Be equipped with stereotype on the detector array, place the foamed rubber layer on the stereotype, detector array is contained and be fixed on the metal frid by metal housing.
The utility model is owing to adopted above-mentioned structure, will by each scintillation crystal and photodiode be bonding and single detector that form is arranged in order, and the partition that adopts heavy metal such as tungsten to make, each detector is isolated, and lay a stereotype in each partition top, the ray that has improved detector so greatly resists harasses and anti-scattering power.In addition, use mildew-resistant, lucifuge, moistureproof glue to be coated in metal housing and be connected the place, slit with metal frid, insulator etc., one side is lucifuge fully, has increased the electromagnetism interference free performance of detector array on the other hand.Before and after the detector crystal and between the outer cover, between stereotype and the outer cover foamed rubber layer is housed, improved shockproof properties.Therefore the utlity model has anti-scattering, anti-ly harass, lucifuge, protection against the tide, shockproof, the dead band is little, characteristics such as detachable.For the detector that uses single photodiode and single crystal to form, during maintenance, can also be changed single detector, need not destroy a fundamental measurement unit.Make and check that fault is very convenient, greatly reduce maintenance cost.
