摘要： Human body back-scattering inspection systems and methods are disclosed. In the invention, X-rays modulated by the flying-spot forming unit having spirally distributed flying-spots have a distribution having alternating peaks and valleys on the irradiated surface. In this way, scanning starting times can be precisely controlled to cause two devices to have scanning starting times that are different by a half of a cycle. That is, the beams outputted from one device are at maximum when the beams outputted from the other device are at minimum. In other words, even if the ray source of one device emits rays, it will not significantly affect imaging result of the other device. In such way, the two devices may emit rays and perform scanning at the same time, and thus the total scanning time is reduced.

摘要： A human body back-scattering inspection method and system are discloses. The method includes: obtaining a back-scattering scan image of a human body under inspection; distinguishing a body image from a background image in the back-scattering scan image; and calculating a feature parameter of the background image to determine whether radioactive substance is carried with the human body. With some embodiments of the present disclosure, it is possible to determine whether any radioactive substance is carried with a human body during back-scattering inspection of the human body. In further embodiments of the present disclosure, it is possible to approximately determine which part(s) of the human body carries the radioactive substance. This improves efficiency of inspection.

摘要： The present invention discloses a millimetre wave three dimensional holographic scan imaging apparatus and a method for inspecting a human body or an article. The apparatus comprises a first millimetre wave transceiver module, a second millimetre wave transceiver module, a first guide rail device to which the first millimetre wave transceiver module is connected in slidable form, a second guide rail device to which the second millimetre wave transceiver module is connected in slidable form, a driver configured to drive the first/second millimetre wave transceiver module to move along the first/second guide rail device, and a constrainer configured to constrain kinematic relation between the first and the second millimetre wave transceiver modules such that they only move in directions opposed to each other. They may increase scan speeds, improve scan stability, reduce scan operations and enhance the reliability of the apparatus.
