Reconstruction of single shot gradient echo rosette images is challenging in 3T. We present a robust reconstruction method that can reconstruct R2*-and-field-map corrected (and R2* weighted) images from low accuracy field maps. Beyond the robust dynamic field map correction, the proposed method produces a more accurate field map from the phase of reconstructed images. A human experiment results are presented.
