Abstract: An inspection system and method, the system includes: a ray source rotatable between at least two scanning positions around a rotation axis, a rotation angle of the ray source between two adjacent scanning positions being greater than an angle of adjacent target spots of the ray source relative to the rotation axis; a detector assembly; and a conveying device for carrying an object. The ray source and the detector assembly are movable in a traveling direction relative to the conveying device so that the object enters an inspection region. When the ray source is at one of the scanning positions, the ray source and the detector assembly move in the traveling direction and the ray source emits X-rays; and when the ray source and the detector assembly move a predetermined distance in the traveling direction, the ray source rotates around the rotation axis to another one of the scanning positions.

Abstract: An inspection system and method, the inspection system includes: a carrying device, at least one ray source and a detector assembly. The ray source and the detector assembly are lifted or lowered along a central axis of the carrying device relative to the carrying device. When viewed along the central axis, the ray source is translatable between scanning positions relative to the carrying device. When the ray source is at one of the scanning positions the ray source and the detector assembly are lifted or lowered relative to the carrying device along the central axis, and the ray source emits X-rays; and when the ray source and the detector assembly are lifted or lowered a predetermined distance the ray source translates to another scanning position. The inspection system further reconstructs a three-dimensional scanning image of the object to be inspected based on detection data of the detector assembly.
