Patent ID: 8678647

Claim:
An imaging apparatus, comprising: a source having a fixed focal spot from which a radiation beam is emitted, wherein the source is enclosed within a source housing; a detector located at a distance from the source and positioned to receive the radiation beam from the source along a first trajectory; a detector positioner that translates the detector from a first position to a second position in a direction that is substantially normal to the first trajectory of the radiation beam from the fixed focal spot; and a beam positioner that alters the trajectory of the radiation beam to direct the radiation beam onto the detector located at least at both the first position and the second position, wherein the beam positioner includes a servomotor linear actuator to move the source about the fixed focal point; a detector positioner frame that includes two side walls and a plurality of lateral frames extending between the two side walls; wherein the detector positioner is moveably mounted upon the detector positioner frame; wherein the detector positioner frame allows the detector to be translated along an arc between the first position and the second position.
