Abstract

Compensation can be provided for rotational and translational motion of a detector relative to the X-ray source in a C-arm X-ray device by warping the image on the detector plane to a virtual detector plane and then mapping the image into three-dimensional space. By using a virtual detector, the computations required to reconstruct the three-dimensional model are greatly simplified.
