Abstract

The invention discloses a monitoring device and a method of radioactive material imaging based on multi-detector, wherein the device comprises: at least two detecting elements comprises at least one imaging or positioning detecting element, and the remaining detecting elements are combinations of one or more counting, imaging or positioning detecting elements, and at least one imaging or positioning detecting element and at least one remaining detecting element are spatially separated from each other; an imaging assembly is connected with each detecting element of multiple detecting elements,the imaging result is obtained according to the imaging information or the positioning information detected by at least one imaging or positioning and detecting element and the counting intensity information or the image information or the positioning information detected by the remaining detecting elements. The device can make the output information of the imaging assembly achieve better imagingor positioning effect, and the imaging field of view is expanded, and the detection sensitivity is improved, image quality or positioning is accuracy.

Description

technical field [0001] The invention relates to the technical field of radiation detection, in particular to a multi-detector-based radioactive material imaging monitoring device and method. Background technique [0002] At present, radioactive substances widely exist in nature and are used in industry, agriculture, medical care and other industries. The monitoring of radioactive substances by detecting the radiation emitted by radioactive substances is of great significance to ensure the normal storage and application of radioactive substances in specified places, prevent accidental leakage, loss or illegal transfer, and prevent radioactive substances from being used in terrorist attacks and endangering public safety. . [0003] Existing radioactive detection technologies include two types: 1) Counting and detecting devices, which only record the counting intensity information of radioactive sources irradiating detectors, and cannot obtain the orientation of radioactive so...
