A method for image acquisition includes selectively concealing and exposing an X-ray source to a target object while the X-ray source travels along a first path and moving an X-ray detector along a second path in a first direction while the X-ray source is exposed to the target object. The method further includes moving the X-ray detector along the second path in a second direction generally opposite the first direction while the X-ray source is concealed from the target object.
