Abstract: Methods and apparatus for integrating a table with at least one X-ray source for medical imaging of patients. The apparatus comprises a table on which a patient may be placed, at least one X-ray source configured to generate X-rays at a plurality of X-ray source locations along a linear direction, wherein the at least one X-ray source is arranged to generate the X-rays such that at least some of the X-rays pass through a portion of the table in addition to passing through a portion of a patient placed on the table, and at least one detector array comprising a plurality of detector elements and arranged to detect the at least some of the X-rays passed through the portion of the patient placed on the table, wherein the at least one detector array comprises detector elements arranged in a two-dimensional configuration. Iterative reconstruction techniques may be used to reconstruct an image from X-ray data detected using the at least one detector.

Abstract: Radiation is directed at an object, and radiation scattered by the object is sensed. An angular distribution of scatter in the sensed scattered radiation relative to a path of the radiation directed at the object is determined, and the angular distribution is evaluated. One or more atomic numbers, or effective atomic numbers, of materials composing the object is determined based on evaluating the angular distribution.
