Abstract
In a method and apparatus to reduce movement artifacts in magnetic resonance images an essentially unmoving area of a region to be imaged is located in a region of high sensitivity of a first group of individual local antennas, and a moving area is located in the region of high sensitivity of a second group of local antennas. Spatially coded magnetic resonance signals are received by a first group of the local antennas and are individually processed further. Spatially coded nuclear magnetic resonance signals are received by the second group of local antennas and are combined with a weighting, using weighting factors. The weighting factors are determined so as to reduce gradient of the weighted, combined, spatially dependent sensitivity of the local antennas of the second group.
