摘要: A human body back-scattering inspection method and system are discloses. The method includes: obtaining a back-scattering scan image of a human body under inspection; distinguishing a body image from a background image in the back-scattering scan image; and calculating a feature parameter of the background image to determine whether radioactive substance is carried with the human body. With some embodiments of the present disclosure, it is possible to determine whether any radioactive substance is carried with a human body during back-scattering inspection of the human body. In further embodiments of the present disclosure, it is possible to approximately determine which part(s) of the human body carries the radioactive substance. This improves efficiency of inspection.

摘要: A ray emission device and an imaging system with the ray emission device are disclosed. The ray emission device comprises: a cylinder; a ray source disposed in the cylinder for emitting a ray; and a collimator disposed in the cylinder. The collimator enables the ray emitted by the ray source to form sectorial ray beams at a plurality of positions in an axial direction of the cylinder. The cylinder has a pencil beam forming part arranged over an axial length of the cylinder corresponding to the plurality of positions. The sectorial ray beams form pencil beams through the pencil beam forming part when the cylinder rotates around a rotation axis.
