1. An imaging method, comprising: positioning an X-ray source on a first side of a subject to be imaged such that the X-ray source faces the subject; positioning a detector on a second side of the subject such that the detector faces the subject; linearly translating the X-ray source and the detector by simultaneously moving the X-ray source and the detector in opposite or approximately opposite directions while the X-ray source supplies X-rays and the detector acquires tomographic data of the subject; and reconstructing a Computed Tomography (CT) image based on the tomographic data wherein linearly translating the X-ray source and the detector is performed twice, and wherein a first path traveled by the X-ray source during the first linear translation step is orthogonal to a second path traveled b the X-ray source during the second linear translation step.
