    摘要： A human body security inspection apparatus, a method of operating the same, and an associated filter device are disclosed. The human body security inspection apparatus includes a radiation beam exit configured for emitting a radiation beam; a beam guiding box configured for guiding the radiation beam; and a filter device configured between the radiation beam exit and the beam guiding box. The filter device includes a housing and a filter cage having a central axis. The filter cage is formed by arranging two or more pairs of filtering sheets, which are made of different materials and/or have different thicknesses, in an encircling way. The filter cage is rotatable about its central axis such that at least one pair of filtering sheets is capable of filtering the radiation beam to adjust an outputted dosage of the radiation beam of the human body security inspection apparatus.

    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： An inspection system included a ray source to emit a ray, a detector to receive the ray, a detection region for placing an object under inspection, and a moving device to move the ray source and the detector around the detection region. Conventional scanning blind zones such as both sides of a human body, both sides of arms and both sides of legs can be completely eliminated. In addition, it is not necessary for a human body under inspection to carry out an action such as turning around to change his or her posture. Therefore, ineffective time can be minimized in the entire detection and a passing rate of persons under inspection can be improved. Furthermore, an inspected person's mental feeling of being controlled due to change of posture can be greatly improved, and his or her mental discomfort and conflicted moods can be 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.
