Helical Acquisition ... In this approach, image acquisition time is decreased significantly by connecting the tube voltage cables through a "slip ring," a sliding contact mounted on the rotating gantry of the unit. With slip-ring technology, the X-ray tube rotates while the patient table moves without stopping. Hence, the patient is moved continuously through the gantry during the study, and the X-ray beam maps out a helical path in the patient ...  3, fiche 1, Anglais, - helical%20acquisition
