1. A method for acquiring magnetic resonance data with a magnetic resonance examination apparatus, comprising the steps of:

  • exciting nuclear spins in an examination region of a subject by irradiating the subject with RF energy, thereby causing emission of magnetic resonance signals from the examination region;

    with an array of frequency conversion units, receiving said magnetic resonance signals and converting said magnetic resonance signals into frequency-converted signals in a common frequency band;

    radiating said frequency-converted signals to generate a signal field that contains location information identifying a location of acquisition of the magnetic resonance signals;

    spatially positioning a plurality of reception antennas in an antenna array for spatially-resolved acquisition of said signal field, each reception antenna generating an acquisition signal that contains said location information; and

    computationally reconstructing an image of said examination region from said acquisition signals received by said plurality of reception antennas in said antenna array.
