Problems solved by technology

However, when two devices stand facing each other, usually the two devices cannot emit beams at the same time, because when one device scans, if the other emits beams, it will generate a signal on the detector of the normally scanning one, so Can't get a normal scan image

Abstract

The invention discloses a human body backscatter safety check system and a method thereof. A device begins scanning while the other device maintains unmoved; when a first device scans until even if a second device emits a beam, the beam is not directly incident on the detector of the first device, the second device begins scanning; the scanning speeds of the two devices are consistent, therefore, during a scanning process, the rays of the two devices are not directly incident on the detector of an opposite device; and after the first device finishes scanning, the second device continues scanning until the end. Compared to respective scanning by two devices, such a scanning process has the advantage of shortened time, and the specific shortened time is decided by how long after the first device carries out scanning when the beam emission of the second device does not exert an effect on the first device.

Description

Technical field [0001] The technology relates to radiation imaging technology, in particular to a human backscatter security inspection system and method thereof, which can increase the scanning speed of the security inspection system. Background technique [0002] Backscatter imaging technology is one of the main technologies for human body security inspection. Scattered images can be obtained by scanning the human body with X-ray beams and using a large-area detector to receive the scattered signals. During data processing, the scanning position and the scattered signal can be corresponded to each other. [0003] When the backscatter device and the scanned person are not moving, only one side of the scanned person can be scanned in one scan. If you want to perform a complete security check on the human body, the person under inspection needs to turn around after scanning one side, and then scan the other side again. [0004] In order to improve inspection efficiency, many manufact...
