BACK-SCATTER HUMAN BODY SECURITY INSPECTION SYSTEM AND SCANNING METHOD THEREOF TO DETECT RADIOACTIVE MATTER
First Claim
1. A back-scatter human body security inspection system, which is capable of detecting a radioactive matter carried by the human body, comprising:
- a radiation source configured to generate radiation rays;
a flying spot forming device, configured to modulate the radiation rays from the radiation source, so as to form flying spot scanning beams for scanning the human body to be detected;
a detector configured to detect radiation rays from the human body to be detected and output a signal characterizing a dose of the radiation rays;
a control and data processing device, configured to process the signal outputted from the detector to obtain a radiation image of the human body to be detected,wherein the detector detects the radiation rays from the radiation source scattered by the human body to be detected, and the radiation rays from the radioactive matter carried by the human body to be detected, separately at different times.

Abstract
The present invention discloses a back-scatter human body security inspection system, capable of detecting a radioactive matter carried by the human body, comprising: a radiation source configured to generate radiation rays, a flying spot forming device, configured to modulate the radiation rays from the radiation source, so as to form flying spot scanning beams for scanning the human body to be detected, a detector configured to detect radiation rays from the human body to be detected and output a signal characterizing a dose of the radiation rays, a control and data processing device, configured to process the signal outputted from the detector to obtain a radiation image of the human body to be detected. The detector detects the radiation rays from the radiation source scattered by the human body to be detected, separately at different times, and the radiation rays from the radioactive matter carried by the human body to be detected. In the present invention, the application ranges of the back-scatter human body scanning apparatus can be effectively expanded, without adding and modifying the hardware therein, thereby increasing the monitoring function to the radioactive matter carried by the human body and further improving the effects of the human body security inspection.
