Abstract: The present disclosure discloses a vehicle-mounted type back scattering inspection system. The vehicle-mounted type back scattering inspection system includes a carriage and a back scattering imaging device, the scanning range of the back scattering imaging device is variable. As the scanning range of the back scattering imaging device of the present disclosure is variably set, the inspection range of the back scattering imaging device can be expanded.

Abstract: The present disclosure discloses a radiation inspection system and a radiation inspection method. The radiation inspection system comprises a radiation source and a beam modulating device. The beam modulating device comprises a first collimating structure disposed at a beam exit side of the radiation source and a second collimating structure disposed at a beam exit side of the first collimating structure. The second collimating structure is movable relative to the first collimating structure to change a relative position of the first collimating port of the first collimating structure with the second collimating port of the second collimating structure, and the beam modulating device is shifted between a first operational state in which the beam modulating device modulates an initial beam into a fan beam, and a second operational state in which the beam modulating device modulates the initial beam into a pencil beam variable in position.
