Streaking artifacts in radial MR imaging due to gradient nonlinearities are suppressed using a beamforming algorithm where region growing image segmentation is used to automatically generate the interference covariance matrix. The performance of the automatic streaking artifact suppression algorithm (RGB-STAR) is compared to algorithms based on coil removal and coil weighting and a beamforming algorithm with manual segmentation.
