Radiation detection method, device, detector component and radiation detector

Abstract

The present invention provides a ray detection method and a device, a detector assembly and a ray detector, relating to the field of radiation imaging. The ray detection method provided by the invention comprises: obtaining basic detection data of each transfer layer in the detector assembly, the detector assembly consisting of a plurality of transfer layers in a multilayer arrangement, each transfer layer being configured to detect energy in a preset detection range; and obtaining ray detection data of a preset detection level on the basis of the combination of the basic detection data of the plurality of transfer layers. According to the ray detection method provided by the invention, on the basis of the basic detection date of the plurality of transfer layers, the ray detection data of the preset detection level is acquired according to the requirement of the detection level and the basic detection data of the transfer layers in accord with the preset detection level, therefore the energies of different energy levels may be flexibly detected according to the requirement of detection.

Description

technical field [0001] The invention relates to the field of radiation imaging, in particular to a radiation detection method, device, detector assembly and radiation detector. Background technique [0002] In the radiation imaging security inspection system, the line scan imaging method is generally adopted, and the array detector converts the X-ray or γ-ray signal passing through the detected object into an electrical signal. The X-ray interacts with the matter, passes through the illuminated object and attenuates, and is converted into an electrical signal by the detector to form an image. Traditional single-energy X-ray fluoroscopy imaging gives an image formed by the cumulative density information of the object in one perspective direction, but cannot give other information such as material density or material composition. After the X-ray with energy spectrum distribution penetrates the object to be inspected, the energy spectrum will change, and the change is related ...

Problems solved by technology

Such a structure solves the above-mentioned problems to a certain extent, but as a dual-energy detector, its coexistence with traditional dual-energy detectors is still unavoidable, that is, since the thickness of the scintillator has been determined at the time of manufacture, the detection of the detector The energy range has been determined, its applicability is not wide
