FIELD: physics.SUBSTANCE: method involves two-sided scanning of the inspected person with thin beams of X-rays from two X-ray sources placed at different sides of the inspected person by vertical sweeping through linear vertical movement of said sources using carriages fitted with an electric drive and horizontal sweeping using collimators and picking up backscattered X-rays using a detector mounted at each carriage to form raster images of the inspected person in one scanning cycle, wherein linear vertical movement of both X-ray sources is carried out simultaneously and asynchronously with delay of the beginning of scanning one relative to the other, and scattered X-rays, passing from an opposite X-ray source, is absorbed by protective shields at each of the detectors.EFFECT: high throughput when inspecting people.9 cl, 2 dwg |
