Abstract: The disclosure relates to a local coil as well as a system including a magnetic resonance tomography system with a local coil. The local coil includes a data source and a signal output in signal communication with the data source for outputting data from the data source. The data source is configured to transmit a plurality of data items via the signal output. To this end, the signal output includes a radio-frequency source and a modulator and is configured to modulate to transmit the data from the data source onto a carrier frequency of the radio-frequency source by the modulator.

Abstract: A device for recovering a temporal reference in a free-running magnetic resonance tomography (MRT) receive chain includes a time reference encoder and a time reference decoder. The time reference encoder is configured to generate a modulation signal as a function of a reference clock, where the modulation signal is configured for a correlation with a temporal resolution less than a maximum predetermined phase deviation and a maximum that may clearly be identified. The time reference decoder is configured to receive, via the first signal input, a receive signal as a function of the modulation signal, perform a correlation with a reference signal, and generate a signal as a function of a temporal reference of the modulation signal in the receive signal in relation to the reference signal.

Abstract: A magnetic resonance device includes at least one gradient amplifier and at least one gradient coil. The magnetic resonance device also includes a switching matrix unit that is embodied flexibly to connect the at least one gradient amplifier to the at least one gradient coil. A preliminary pulse sequence for the magnetic resonance device provides that in the optimized pulse sequence, a sufficient number of gradient amplifiers is available at any point for operating the gradient coils used.

Abstract: A magnetic resonance tomography system includes a plurality of MRT plugs for connection of antenna elements, respectively, of one of a plurality of local coils. Due to at least one analog switch matrix, antenna elements respectively connected to fewer than all of the MRT plugs may be connected in an analog fashion to receive signal processing elements of one of a plurality of receive signal processing element blocks respectively having a plurality of receive signal processing elements. Between outputs of receive signal processing element blocks and an evaluation device of the magnetic resonance tomography system, a digital channel selection unit is provided. On an input side of the digital channel selection unit, the digital channel selection unit may be connected to antenna elements. Signals from fewer antenna elements are present at the output of the digital channel selection unit than at an input of the digital channel selection unit.

Abstract: A cooling system for a magnetic resonance tomography system is provided. The cooling system includes a first coolant circuit with a first coolant pump and a first heat exchanger in thermal contact with an object to be cooled. The first cooling circuit further includes a switchover apparatus that is configured to adjust a heat flow from the first coolant circuit optionally to a first heat sink and/or a second heat sink. In such cases the second heat sink is a second heat exchanger that is fluidically connected to an emergency cooling system.
