Illustration of gradients and k-space coverage for the Wave-CAIPI method are shown in (A). The linear readout direction gradient X is combined with sinusoidal gradients in Y and Z. CAIPIRINHA staggered Cartesian sampling is used for efficient encoding of k-sapce. The forward model used for Wave-CAIPI reconstruction is shown in (B). Both the image and the separable PSF terms PY and Pz are considered variables in the joint optimization approach. The aliasing effect based upon the Wave-CAIPI encoding scheme is shown below.
