Reconditioning Process:
All equipment goes through a multi-step reconditioning process. Each unit is restored to a like-new status. The rotating x-ray tube allows for greater penetration and resolution for the lumbar area when doing needle localizations or other work involving the thicker anatomical areas of patients. For barium swallows a VCR or Digital Video Recorder can be utilized for better record keeping and post study analysis.
