Method for sampling a received radio-frequency signal, in particular a radio-frequency signal from a receiving coil in a magnetic resonance apparatus

摘要

In a method for sampling a received radio-frequency signal, in particular a radio-frequency signal from a receiving coil in a magnetic resonance apparatus, the received radio-frequency signal is down-mixed to a low-frequency baseband such as for image production. The radio-frequency signal from a receiving coil in a magnetic resonance apparatus is passed directly to a high clock rate analog/digital converter where it is converted, as a function of the clock, to a lower frequency, after which it is down-mixed by digital demodulation to a baseband at an even lower frequency.
