Method for image generation by magnetic resonance

A method for generating an image by magnetic resonance, comprising the steps of:

• emitting radio-frequency excitation pulses into an imaging volume for exciting nuclear magnetic resonance signals in said imaging volume;
• generating at least one gradient field in said imaging volume for location-coding said nuclear magnetic resonance signals to produce location-coded magnetic resonance signals;
• receiving said location-coded magnetic resonance signals with a plurality of independent reception antennas, each having a sensitivity profile, with the respective sensitivity profiles of said reception antennas differing from each other, said reception antennas respectively generating reception signals;
• generating a plurality of k-space data sets respectively from the reception signals from the plurality of reception antennas, each k-space data set having middle k-space rows and outer k-space rows, with said middle k-space rows being more densely disposed in said k-space data set than said outer k-space rows, and decorrelating said k-space data sets relative to each other with regard to noise signals;
• reconstructing a plurality of intermediate images respectively from said k-space data sets;
• identifying the respective sensitivity profile for each of said reception antennas from the middle k-space rows of the k-space data set respectively generated from the reception signal from that reception antenna;
• and
• combining said intermediate images dependent on said sensitivity profiles to form an overall image of at least a portion of said imaging volume.
