Motion is a dramatic factor of image quality degradation in MRI. Dynamic MR can be used for limiting the effect of motion during the acquisition. We propose to combine a conventional sliding window reconstruction with a Fourier-based registration technique in order to correct for rigid motion in highly segmented radial acquisitions. The proposed method has been compared to image-based registration and was successfully applied in-vivo on 6 volunteers for 2D brain imaging.
