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.

摘要： In a magnetic resonance tomography local coil arrangement and a method for processing signals received thereby, at least one local coil is fashioned to receive at least one reception signal and at least one amplifier is provided that amplifies the at least one reception signal. A frequency converter generates at least one intermediate frequency signal from the at least one reception signal the intermediate frequency of the intermediate frequency signal differing from the reception signal frequency of each reception signal. An analog-digital converter converts the analog intermediate frequency signal into a digitized signal. A shielding device shields against at least radio-frequency signals, the shielding device surrounding at least the analog-digital converter. At least one frequency filter is arranged between the at least one local coil and the analog-digital converter, the frequency filter exhibiting a transmission range for signals with the intermediate frequency of an intermediate frequency signal. The digitized signal is transmitted from the local coil arrangement.
