摘要： 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 (114) disposed at a beam exit side of the radiation source and a second collimating structure (130) 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, such that 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. The radiation inspection system and the radiation inspection method of the present disclosure may incorporate the inspection efficiency and the inspection accuracy.

摘要： The present invention discloses an article inspection device, comprising: a x-ray machine, a collimation unit, a transmission detector array and at least one scattering detector array. Each of the at least one scattering detector array comprising a plurality of same scattering detector modules arranged in a matrix of i-rows and j-columns. A transmission cross section of the article transmitted by the x-rays is divided into a plurality of same sub-regions arranged in a matrix of i-rows and j-columns. The plurality of scattering detector modules arranged in i-rows and j-columns correspond to the plurality of sub-regions arranged in i-rows and j-columns one by one for detecting pair production effect annihilation photons and Compton-effect scattering photons from the respective sub-regions. Obtaining atomic numbers of the respective sub-regions based on a ratio of the pair production effect annihilation photon count to the Compton-effect scattering photon count, so as to form a three-dimensional image of the article. In addition, the present invention further discloses an article inspection method.
