DEVICE FOR MOUNTING AND DRIVING A ROTATABLE PART OF A GANTRY OF A COMPUTER TOMOGRAPHY UNIT AND COMPUTER TOMOGRAPHY UNIT

摘要

A device for mounting and driving a rotatable part of a gantry of a computed tomography system with respect to a stationary part of the gantry around a system axis of the stationary part, has a magnetic bearing that magnetically supports the rotatable part relative to the stationary part, and an electromagnetic drive that drives the rotatable part of the gantry relative to the stationary part.
