Abstract: A photoneutron conversion target for generating photoneutrons by directing an x-ray beam at the photoneutron conversion target includes an elongated body having a first end and a second end. When the photoneutron conversion target is in use, the x-ray beam enters the body and propagates in a direction from the first end to the second end. The body of the photoneutron conversion target is shaped such that propagation of the x-ray beam is substantially proportionate to an intensity distribution of the x-ray beam, so that the greater an intensity of x-rays of the x-ray beam, the greater the propagation distance of the x-rays within the body of the photoneutron conversion target. The photoneutron conversion target according to the invention can make full use of the x-ray beam so as to increase a yield of photoneutrons.

Abstract: 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.
