In this study, we extended the multifrequency interpolation (MFI) algorithm to three dimensions (3D) and performed off-resonance correction for the 3D cones trajectory. Using an emulated low-resolution field map of isotropic 5 mm resolution, we have demonstrated the feasibility of MFI in both phantom and in vivo data of isotropic 1 mm resolution, achieving significant improvements in image contrast and detail.
