Abstract

A digital radiographic imaging system includes an offset table for determining mechanical and structural offsets which would, if not corrected, misalign the source and detector during use. The method can correct for inaccuracies in mechanical linkages, examination rooms and other mounting structures, and “drift” induced during use of the system.
