Aliasings occurred due to undersampled phase-encodings in accelerated MR imaging are separated to readout direction by applying additional gradient along undersampled direction at readout timing. Resolution and FOV are redefined due to voxel modification as sheared form. With this method, 6x acceleration is achieved in high-resolution invivo 3D imaging with a partial loss of diagonal resolution. Further acceleration is possible by using parallel imaging techniques such as SENSE and GRAPPA.
