Abstract
A magnetic resonance tomography unit includes a transmitter, a transmission monitoring device for monitoring an excitation signal from the transmitter, and a plurality of transmit antennas. The magnetic resonance tomography unit also includes a switching device configured to bring the transmission monitoring device selectively into a signal connection to one transmit antenna of the plurality of transmit antennas. A method for operating the magnetic resonance tomography unit is also provided.

A magnetic resonance tomography unit comprises:
- a transmitter;
- a transmission monitoring device configured to monitor an excitation signal from the transmitter;
- a plurality of transmit antennas;
- and
- a switching device configured to bring the transmission monitoring device selectively into a signal connection to one transmit antenna of the plurality of transmit antennas.
A method for operating a magnetic resonance tomography unit including a transmitter, a transmission monitoring device for monitoring an excitation signal from the transmitter, a plurality of transmit antennas, and a switching device configured to bring the transmission monitoring device selectively into a signal connection to one transmit antenna of the plurality of transmit antennas, the method comprising:
- connecting a transmit local coil to the magnetic resonance tomography unit;
- making a signal connection between the transmission monitoring device and the transmit local coil using the switching device;
- emitting an excitation signal from the transmitter via the transmit local coil;
- receiving a monitoring signal from the transmit local coil via the signal connection to the transmission monitoring device;
- comparing the monitoring signal with a reference value;
- and
- interrupting the emission depending on the comparison.
