X ray human body fluoroscopy security check system capable of performing partial scanning

Abstract

The invention discloses an X ray human body fluoroscopy security check system capable of performing partial scanning, which comprises an X ray generator (10), an X ray detector (20), a collimator (30), a movable platform (40) and an imaging device (50), wherein the movable platform (40) is arranged between the collimator (30) and the detector (20) and does reciprocating motion; an optical shutter device (60) is arranged in an X ray passage of the collimator (30) and comprises an optical shutter core (61) for defining a scanning region, a bearing (62) for supporting the optical shutter core, a motor (63) for driving the optical shutter core to rotate and a short shaft (64) for supporting and fixing the optical shutter core; and a plurality of X ray windows (65) corresponding to different parts of a human body are arranged at different positions on the optical shutter core (61), so that X ray irradiates the whole human body or a partial detection part of the human body through the X ray windows (65). According to the system, partial scanning can be performed aiming at a specific part of the human body, and the scanning coverage range can be adjusted, so that the radiation of X ray to the human body can be effectively reduced.

Description

【Technical field】 [0001] The invention relates to a public security inspection system used in airports, customs and other occasions where security inspection is required, in particular to an X-ray human body perspective security inspection system capable of partial scanning for certain specific parts of the human body. 【Background technique】 [0002] At present, terrorist activities and drug trafficking activities worldwide are becoming more and more rampant, seriously endangering 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 in important places such as airports and customs, and installing security check equipment for human bodies and bags at the entrances and exits of various important departments. For luggage, X-ray perspective imaging technology is mainly used at present. For the inspection of...
