Abstract
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.
Claims3
A sealed component for a magnetic resonance imaging scanner comprising:
- cured sealing compound comprising at least one RF coil therein and at least one gradient coil therein for magnetic resonance imaging;
- and
- an actuator module comprising an actuator for active noise control during magnetic resonance imaging, said actuator having opposite ends, two holding segments respectively rigidly fastened to the opposite ends of the actuator, two actuator receiving elements respectively fastened to the two holding segments, said two actuator receiving elements being embedded in the cured sealing compound with a spacing between said two actuator receiving elements, and each of said two receiving elements having a fastening segment that protrudes into a recess in the cured sealing compound.
