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.
