A transmission arrangement for a tomograph, such as magnetic resonance tomography, is provided for wireless energy supply of a local coil system. The transmission arrangement includes at least one first region having at least one first antenna element. The transmission arrangement further includes at least one second region having at least one second antenna element. The at least one first region and the at least one second region are connected to one another via at least one rejector circuit.

A local coil system for detecting magnetic resonance (MR) signals in a magnetic resonance tomography (MRT) device includes an energy reception antenna for inductively receiving energy for the local coil system from a magnetic field changing over time with an energy transmission frequency. The energy reception antenna includes a conductor loop running in loop-like fashion from a first loop connection to a second loop connection. At least one path filter that blocks for harmonic frequencies of the energy transmission frequency is arranged over the course of the energy reception path, and/or at least one path filter that blocks for harmonic frequencies of the energy transmission frequency is arranged over the course of an energy reception path leading from the loop connections to a rectifier.

A method for wireless transfer of energy to a local coil system for a magnetic resonance system is provided. The method includes determining an energy requirement value representing a minimum energy level to be fed to the local coil system, so that the local coil system may carry out a predetermined function over a predetermined time period. Energy is transferred adaptively to the local coil system depending on the energy requirement value.

Adaptive energy transfer to a local coil system

The present embodiments relate to a local coil system for a magnetic resonance system. The local coil system includes at least one local coil for detecting MR response signals and at least one transmitting device for the wireless transmission of signals to a receiver of the magnetic resonance system. The local coil system is embodied with a transmitter-side diversity. A receiver-side diversity may exist in the magnetic resonance system.

Local coil system

A local coil system for a magnetic resonance system has a local coil for detecting MR response signals and a transmitter for wirelessly transmitting signals to the magnetic resonance system. At least one pseudo random device is operable to change signals in a pseudo random fashion in order to avoid interferences in the imaging.
