Abstract: A linear track scanning imaging system and method, the imaging system comprising: a ray generating unit comprising a plurality of ray sources, where the plurality of ray sources emit beams alternately and only one ray source emits a beam at a same time; an actuating means for causing an object under examination to perform a relative movement with respect to the linear track scanning system along a linear track, thereby leading the object under examination to pass through the scanning area of the linear track scanning imaging system; a data collecting unit which collects the projection data of the object under examination for each ray source respectively; an imaging unit which reconstructs an image of the object under examination based on the projection data collected for each ray source; and a display unit for displaying the reconstructed image. By adopting a plurality of ray sources arranged according to a certain spatial distribution and emitting beams alternately according to a certain time sequence, it is possible to achieve a larger scanning viewing angle with a shorter detector length, thereby reducing the number of the detector units required by the system and shortening the total scanning distance of the examined object.

Abstract: The present application discloses a multi-view backscatter inspection system and an inspection method. The inspection system comprises an inspection passage, at least two inspection units, a control device and a data processing device. The inspection unit comprises a radiation source and a detector array. The detector array comprises at least two detector modules arranged at different positions and independent of each other. At least two inspection units are arranged so that a radiation beam from any inspection unit is directed to the outside of the detector array of each of the remaining inspection units. The control device adjusts a phase difference between radiation beams of various radiation sources, so that an effective detection area of each of the detector arrays is far away from an interference area. When an inspection image corresponding to certain detector array at certain moment is formed, the data processing device calculates an effective detection area of the detector array at the moment, processes a detection signal from a detector module within the effective detection area and forms an inspection image in which the inspection target is located at one side of the detector array at the moment. The present application may improve the quality of an inspection image.
