Problems solved by technology

[0003] The CT system described in Chinese patent ZL99110839.6 can obtain multi-directional projections and computerized tomography images of the object to be inspected, which greatly improves the detection capability of the equipment, but the system also has the following defects such as: because the CT system needs full-circle rotation , for the inspection of small passenger cars or air containers and other large objects, the whole system structure is complex, the radiation protection requirements are high, the detection pass rate is low, the installation requires a large site, and it is difficult to meet some occasions that require high mobility performance

Abstract

A mobile radiation imaging detection system of car comprises detection unit module, special car and connection mechanism for connecting the said two to be an integral unit. It is featured as forming said detection unit module by ray source, front-back collimators, array detectors, translation drawing mechanism and body-frame; setting translation drawing mechanism between ray source and array detectors to form scan detection channel and connecting detection unit module with special car to start driving on road for carrying out detection operation.

Description

technical field [0001] The invention relates to a movable car radiation imaging detection system. It belongs to the field of nuclear technology application. Background technique [0002] Radiation imaging systems for large objects such as containers and passenger cars in the prior art, including fixed and mobile systems, basically aim at obtaining horizontally projected images of the object to be inspected. This type of system meets the needs of inspecting containers to a certain extent; However, for small passenger cars and some air containers or air cargo boards, since the mass distribution of the inspected object is flat, the mass thickness of the inspected object along the ray direction in the top view projection view is much smaller than that of the horizontal projection perspective image, that is, it increases The possibility of penetration is improved, and the overlapping phenomenon of the image of the object under inspection is reduced, making image identification m...
