A method for operating a mobile magnetic resonance tomography system having magnets andor coils generating a magnetic field and a shield surrounding the magnets andor coils is intended to enable an optimal image quality during the examination and at the same time have a small space requirement. A hoist mast is mounted to the rack, and a vertical support shaft is attached to the rack for stabilizing the game hoist and carrier above a surface during the lifting of an animal carcass. Global snooping is used to provide a single point of serialization of data tags. Behavior of multiple harmonics can be examined in real time and further information obtained regarding physical properties of the concrete. The signal contacts of each quad group are configured to carry relational signals with each other signal contact in the quad group.
