摘要： An arrangement to transmit magnetic resonance signals has at least two reception branches. Each reception branch contains a single antenna of a local coil as well as an amplifier connected with the single antenna, such that an amplified magnetic resonance signal is formed from a magnetic resonance signal that is acquired via the single antenna. In a multiplexer, each input is connected with a respective reception branch, such that the amplified magnetic resonance signals of the reception branch are combined by the multiplexer into a resulting signal using a time multiplexing method. A transmission path is connected on one side with an output of the multiplexer and on the other side with a receiver, such that the resulting signal is transmitted from the multiplexer to the receiver via the transmission path.

摘要： A system for electromagnetic excitation of an object under examination during magnetic resonance tomography includes a radio frequency (RF) device for generating a radio-frequency signal and a plurality of antennas for emitting the radio-frequency signal. A signal connection exists between the output of the RF device and the plurality of antennas. A source impedance of the signal connection to the output of the RF device at a connection point of the plurality of antennas is significantly higher than the impedance of the plurality of antennas at the connection points, so that the plurality of antennas are fed in a current source feed mode if a radio-frequency signal is present.
