Title: Method for generating images by means of magnetic resonance

Abstract: In a method for image generation by means of magnetic resonance, employing a number of independent reception antennas having sensitivity profiles differing from one another, radio-frequency excitation pulses and gradient pulses are emitted into an imaging region, the imaging region which is divided into partial imaging regions, for generating location-coded magnetic resonance signals, the gradient pulses including phase-coding gradients for the location coding in a phase-coding direction, with the location coding in the phase-coding direction being incomplete. The magnetic resonance signals are simultaneously received with the reception antennas, and respective k-space datasets are formed from the reception signals of the reception antenna. An intermediate image is reconstructed from each k-space dataset, the intermediate images including fold-over artifacts due to the incomplete location coding in the phase-coding direction. A fold-over artifact-free, overall image is formed by a weighted combination of the intermediate images with weighting matrices allocated to the antennas. The weighting matrices are determined by taking into account the fold-over artifacts and noise.
