An auxiliary CT tabletop was designed and manufactured such that radiograph
ic images might be acquired, with use of a ceiling-mounted X-ray tube, with
out removing the patient from the CT table. The tabletop required no modifi
cations to the original CT table housing and did not produce artifacts in t
he CT images. Radiographs obtained with the overhead X-ray tube and auxilia
ry tabletop demonstrated image quality equivalent to traditional radiograph
s.
