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.
