摘要： The present invention relates to an inspection system. The inspection system comprises a base, a boom lifting mechanism provided on the base, and a boom mounting a detector. The boom lifting mechanism includes at least two support arms arranged sequentially. The at least two support arms include a base arm and a distal arm. The base arm is connected to the base, the boom is mounted on the distal arm, the inspection system has a scanning state and a transporting state, and two adjacent support arms of the at least two support arms are rotatably connected so that the height of the boom in the scanning state is different from that in the transporting state. The boom lifting mechanism of the inspection system of the present invention lifts the boom by rotatably connecting two adjacent support arms, and presents less required driving force compared to the lifting of the boom directly in a vertical direction in the prior art. Thus, there is less weight of the driving mechanism for driving the lifting of the boom, so as to reduce the self-weight of the inspection system.

摘要： A large-area X-ray gas detector includes a housing having an inner cavity and a ray entrance communicated with the inner cavity, a thin entrance window and a signal collection module. The inner cavity is filled with a working gas which is a non-electronegativity gas sensitive to the X-ray. The entrance window is hermetically connected to the ray entrance such that the X-ray enters into the inner cavity. The signal collection module comprises an anode wire electrode layer and a cathode electrode layer arranged parallel with each other in the inner cavity, in which the anode wire electrode layer has an anode wire for accessing to a high voltage, and the cathode electrode layer is grounded. The anode wire electrode layer collects electrons generated by the working gas under an action of the X-ray.

摘要： The present disclosure provides a decomposition method based on basis material combination. In the present disclosure, a scanned object is divided into a plurality of regions, the basis material combinations used in each of the divided regions are different each other, and the scanned object is re-divided according to the re-determined equivalent atomic number of its each point until the change on decomposition coefficient meets certain conditions. Thereby, a decomposition method based on dynamic basis material combinations is realized, which reduces a decomposition error caused by improper selection of the basis material combination and improves the accuracy of the decomposition and substance identification of the multi-energy CT.
