The pulse sequence for Null Space Imaging. The sequence is analogous to a spin echo sequence, but instead of a linear readout gradient, nonlinear encoding fields (G1 to GK) are used as projection imaging gradients. The total number of projections or encoding fields, K, is equivalent to the number of phase encode steps to be used in a typical Cartesian Fourier sequence.
