Abstract	A novel cardiac magnetic resonance imaging (MRI) acceleration strategy called "NoQuist" is presented. Using this new technique, a more sparsely sampled dynamic image sequence is correctly reconstructed without the Nyquist foldover artifact by reductions in the size of the Fourier model of k-space data for the dynamic image. It does not rely on substitution or interpolation to arrive at a data set sufficient for reconstruction of the dynamic sequence. The proposed "NoQuist" method allows reduction of acquisition time in dynamic MRI scans by eliminating the data redundancy that is associated with the presence of static regions in the dynamic scene. A reduction of acquisition time can be achieved by omitting acquisition of a strategically selected subset of phase encoding views from a conventional equidistant Cartesian acquisition grid.
