Abstract

The invention belongs to the technical field of security inspection, and particularly relates to an image feedback based X-ray imaging energy selecting device and method. The device comprises X-ray sources, an electric control energy filter window, flat panel detectors, a computer and an electric control energy filter window. By adopting the X-ray sources and the flat panel detectors, the advantage of a dual-energy image is reserved, meanwhile, the problem that the texture and thickness of an energy filter material are fixed is solved, the cost is lowered by just adopting one set of X-ray sources and one set of detectors, and the electric control filter window outputs pyramid-shaped X-ray beams, the radiation dosage is low compared with conical X-ray beams, and the safety is high.

Description

Technical field: [0001] The invention belongs to the technical field of safety inspection, and in particular relates to an X-ray imaging energy selection device and a selection method based on image feedback. Background technique: [0002] X-ray security inspection equipment is an important equipment for customs, airports, railway stations, subways, express outlets and other transportation and public facilities luggage security inspections, and is also an important technical investigation equipment for public security agencies. The first barrier of security protection in the field of transportation and public safety provides scientific means to ensure national security, protect personal and property safety, and combat smuggling activities. [0003] Existing security inspection equipment can be divided into single-energy X-ray security inspection equipment and dual-energy X-ray security inspection equipment according to the range of ray energy. Single-energy X-ray security i...
