Abstract

Disclosed are a human body backscattering security inspection system and a method thereof. In the present invention, the modulated X-rays emitted by the flying spot forming device are distributed alternately between crests and troughs on the irradiated surface. Using this distribution, when the two devices scan against each other, by precisely controlling the scan start time, the two devices have a half-cycle misalignment in the scan start time, so that the beam current of one of the two devices At the peak, the other device's beam is at the trough. That is to say, even if the ray source of one device emits a beam, it will not have a significant impact on the imaging of another device. In this way, the beams of the two devices are scanned at the same time, and the total scanning time is shortened.

Description

technical field [0001] The technology relates to radiation imaging technology, in particular to a human body backscatter security inspection system and a method thereof, which can improve the speed of security inspection. Background technique [0002] Backscatter imaging technology is one of the main technologies for human security inspection. By scanning the human body with X-ray beams and using large-area detectors to receive scattered signals, the scattered images can be obtained by corresponding the scanning position with the scattered signals during data processing. [0003] When neither the backscatter device nor the scanned person is moving, one scan can only scan the image of one side of the scanned person. If a complete security check is to be performed on the human body, the inspected person needs to turn around after scanning one side, and then scan the other side again. [0004] In order to improve the inspection efficiency, the backscatter inspection systems of...
