Abstract

In a method for implementation of a magnetic resonance examination, and a magnetic resonance apparatus, and an array for acquisition of magnetic resonance signals, and a magnetic resonance signal at a magnetic resonance frequency are acquired from an examination region with an array of frequency conversion units after an RF excitation and are radiated as frequency-converted signals. The resulting signal field is acquired by a number of reception antennas of a second antenna array, which are arranged at different spatial positions and thus allow a spatial resolution of the frequency-converted signals. The acquired acquisition signals are used for image reconstruction.
