Magnetic resonance apparatus having a bulged interior bore filled with a mass augmentation

摘要

A magnetic resonance apparatus has a basic field magnet with an interior bore having a bulge therein. A mass augmentation device is disposed in the bulge, and is composed of a number of assembled individual segments. The mass augmentation device reduces the propagation of mechanical oscillations that are produced during operation of the magnetic resonance apparatus, and which otherwise would produce unwanted noise.
