Movable X-ray human body whole safety inspection system

Abstract

The invention discloses a movable X-ray human body whole safety inspection system, which comprises a motor vehicle and an X-ray scanning and imaging system arranged in the motor vehicle and used for generating sector-shaped X-ray beams, wherein the X-ray scanning and imaging system comprises an X-ray generator, an X-ray detector, a collimating component for making X-rays form thin sector-shaped ray beams through a narrow aperture for emitting, an image acquiring and processing device for converting a signal output by the detector into a visible image, a control device, a vertical frame and an inspection channel; the X-ray generator and the collimating component are connected with the vertical frame; the inspection channel is formed on the inner lower part of the vertical frame; the X-ray detector and the control device are electrically connected with the image acquiring and processing device respectively; and after an inspected person enters the inspection channel, a movable platform loading the inspected person moves through the sector-shaped X-ray beams, and the sector-shaped X-ray beams are projected onto the X-ray detector after penetrating through the body of the inspected person, and are transmitted to the image acquiring and processing device to generate a visible whole body perspective image.

Description

【Technical field】 [0001] The invention relates to a device for security inspection of personnel entering and exiting non-fixed confidential places such as mobile frontier checkpoints, important meeting places, exhibition halls, etc., and particularly relates to a vehicle-mounted mobile X-ray human body security inspection system. 【Background technique】 [0002] At present, terrorist activities and drug-trafficking crimes are becoming more and more rampant around the world, which seriously endanger the public safety and normal life order of the society. To this end, countries around the world have continuously strengthened their efforts to combat and prevent such criminal activities, such as strengthening security checks at important places such as airports and customs, and installing security check equipment for human bodies and bags at the entrances and exits of various fixed important departments. However, in many unfixed confidential places, the equipment for non-contact ...

AI Technical Summary

Problems solved by technology

The obvious disadvantage of this device is that its X-ray detector is a large-area flat-panel detector, and the emitted X-rays are conical and irradiated on the entire detector plane, so the radiation dose is quite large, which is similar to that of medical chest X-rays. The X-ray machine is equivalent, and it will cause great harm to the personal health of the person being tested, so it can only be used for limited spot checks on individual key suspects, and cannot be used for general inspections on the general population

In addition, since the subject and the transmitter are fixed, only the upper body of the human body can be detected, but not other parts of the human body, so many real suspects have slipped through the net

Therefore, so far, there is no effective equipment in the world that can be applied to the general inspection of people who hide contraband in and out of the body in non-fixed important places, and the security inspection and anti-drug departments of all countries in the world are helpless in the face of severe security situations.
