Image based correction of radial trajectory shifts

When performing MR imaging with radial trajectories time delays of readout gradients cause severe artifacts in the reconstructed images. A correction algorithm was implemented using only the acquired data without additional calibration or template measurements. Radial data were shifted along their readout direction by applying a range of discrete readout shifts. By analyzing the reconstructed image for each shift, a corrected image was obtained fully automatically. The proposed method was tested in phantom and in vivo data and proved its reliability.
