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.
摘要翻译：公开了人体背散射检查系统和方法。在本发明中，由具有螺旋状分布的飞点的飞点形成单元调制的X射线具有在照射面上具有交替的峰和谷的分布。以这种方式，可以精确地控制扫描开始时间，以使两个装置的扫描开始时间不同于周期的一半。也就是说，当从另一个装置输出的光束为最小时，从一个装置输出的光束是最大的。换句话说，即使一个设备的射线源发射光线，也不会显着影响其他设备的成像结果。以这种方式，两个装置可以发射光线并同时进行扫描，因此总扫描时间减少。
