A computed tomography (CT) scanning system including a source operable to emit a cone beam of radiation toward an object, a detector operable to detect radiation emitted by the source and to produce detector values related to projections of an object attenuation, a turntable operable to rotate the object about a rotational axis, and a source mover operable to move the source so as to vary an angle between the cone beam and the rotational axis.
