C-arms and mini C-arms have become standard equipment in many outpatient surgery facilities, where they're used for orthopedic, pain management, urological and many other types of procedures. Well-connected facilities might have access to a staff of radiology experts to help maintain C-arms, provide safety training and often perform all of the fluoroscopy procedures. Independent facilities, however, might be left on their own to determine their compliance with radiation safety and operator-training requirements, which vary from state to state.
