摘要： The present invention discloses a dual-energy ray scanning system, scanning method and inspecting system and relates to the radiation scanning, imaging and detecting field. The dual-energy ray scanning system comprises a ray source for alternately emitting a high energy ray and a low energy ray; a filter comprising a low energy filtering element and a low energy transmitting element; and a control device for controlling said ray source and said filter to make said low energy filtering element of said filter be aligned with a beam exit direction of said ray source when said ray source emits a high energy ray so as to filter low energy portion of said high energy ray out and transmit high energy portion of said high energy ray out, and for controlling said ray source and said filter to make said low energy transmitting element of said filter be aligned with said beam exit direction of said ray source when said ray source emits the low energy ray so as to transmit said low energy ray out. This not only can improve transmissivity of the high energy ray, but also does not lose the spatial wire resolution of the low energy ray, and this guarantees the index of transmissivity and the index of spatial wire resolution at the same time, such that the dual-energy ray can sufficiently utilize a difference in its penetration characteristics to recognize the object to be inspected, thereby reaching the objective of security inspection.

摘要： The present disclosure discloses a volume measurement method, a device, a system and a computer-readable storage medium, and relates to the field of radiation. The volume measurement method includes: determining thicknesses of a measured object in each of directions of multiple X-rays emitted from an accelerator target according to measurement results of the X-rays; determining a cross section area of the measured object according to the thicknesses corresponding to each of the X-rays in the cross section of the measured object; and determining a volume of the measured object according to the cross section area. By applying X-ray scanning to volume measurement, information about the type of substance and size information at multiple positions and angles of the measured object can be obtained from the X-ray measurement results, so that the volume of the measured object can be measured more accurately.
