Sealed component for an MRI scanner having an actuator for active noise control

摘要

Sealed components for an MRI scanner, in particular carrying RF coils and gradient coils have actuators for active noise control that are a part of an actuator module having holding segments fastened rigidly to the opposite ends of the actuator. The holding segments are fastened by screws onto two actuator receiving elements that are embedded at a spacing from one another in the sealing compound, and so that each fastening segment protrudes into a recess in the compound.
