Disclosed is an ultra-low temperature human body infrared scanning and examination system, comprising an ultra-low temperature cooling device, a moving examination platform (6), a first annular portal frame (7), a second annular portal frame (9), an infrared scanning system (8) provided on the first annular portal frame, a CT scanning system provided on the second annular portal frame, a computer system (10) and a printer (11). The moving examination platform is connected with the first annular portal frame the first and the second annular portal frames are connected to each other the infrared scanning system is provided on the inner wall at the top part of the first annular portal frame and the infrared scanning system, the CT scanning system and the printer are electrically connected to the computer system, respectively. Before an examination, the surface of the body is first cooled down so that the temperature of various parts of the body is the same, which reduces thermal background noise and facilitates obtaining an accurate examination result temperature anomalies which are likely to exist on the surface of the body are found by the infrared scanning system then, the position is located using CT scanning finally, the examination result is analyzed by the computer system, in order to detect pathological changes in humans early and treat the patient as early as possible.La présente invention concerne un système de balayage infrarouge et dexamen à ultra-basse température du corps humain, comprenant un dispositif de refroidissement ultra-basse température, une plate-forme dexamen mobile (6), un premier portique annulaire (7), un second portique annulaire (9), un système de balayage à infrarouge (8) disposé sur le premier portique annulaire, un système de tomographie assistée par ordinateur disposé sur le second portique annulaire, un système informatique (10) et une imprimante (11).
