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.

The method includes the recording of x-ray images at different relative positionings of the x-ray device, which contain the first and the second point respectively. The relative positionings are substantially shifted in relation to one another in parallel to a central beam. Stereo reconstruction is carried out to define a 3D position of the first point and of the second point. The distance between the first point and the second point is determined from the 3D position of the first point and the 3D position of the second point.

Abstract: It is possible to reliably avoid a problem that radiation irradiation does not stop even when an accumulated radiation dose reaches a target radiation dose. An AEC unit starts monitoring an integrated value of a radiation dose detection signal from a detection pixel and an output of an irradiation continuation signal at the same time, and continuously transmits the irradiation continuation signal in a predetermined period while the integrated value does not reach a threshold value. When the integrated value reaches the threshold value, the output of the irradiation continuation signal is stopped. The irradiation continuation signal is transmitted to an irradiation signal I/F of a radiation source control device through an irradiation signal I/F by wireless. The radiation source control device stops X-ray irradiation by an X-ray source when the irradiation signal I/F does not receive the irradiation continuation signal.

If not, the start of the irradiation of radiation has been properly detected, the charge accumulation period continues, and radiographic image is imaged.
