A method and apparatus for inspecting an object is present. Radiation is emitted from a radiation source. A beam is formed from a portion of the radiation emitted by the radiation source using a collimator. The collimator is connected to the radiation source by a bearing system comprising a first structure associated with the radiation source and a second structure connected to the first structure. The second structure is configured to hold the collimator. The second structure of the bearing system is moved using a movement system such that the second structure rotates in one of a plurality of directions substantially about a center point in the radiation source while the radiation source remains stationary relative to the second structure. Rotation of the second structure substantially about the center point in the radiation source changes a direction in which the beam is directed.

Single beam backscatter x-ray system

Methods and systems for use in generating a volumetric reconstruction of an object using scattered X-ray radiography. An X-ray beam is directed towards a point within a target object. Scattered X-rays are measured by detectors and measurement data is stored. The X-ray beam is directed towards different points. Measurement data associated with each point is analyzed using a ray tracing methodology to assign contrast values to each point. A volumetric image is generated therefrom.
