WIRE-BASED CALIBRATION APPARATUS FOR X-RAY IMAGING SYSTEMS

Abstract: a calibration target for use with a radiographic image detector includes a target body securable to the image detector and a plurality of radiopaque linear markers, e.g. wires, fixed to the target body, wherein access to the image detector by incident radiation is at least partially blocked by the plurality of linear markers. by using the geometric properties of wires and advanced detection techniques, a precise calibration suitable for high-quality, volumetric three-dimensional ct reconstruction from biplanar x-ray images is achieved.
