In this work, we developed and evaluated a method for reducing motion sensitivity of auto-calibration data for parallel imaging in 3D MRI, with application to high-resolution diffusion imaging at ultra-high field. With the proposed Slice-FLEET method, we successfully achieve high resolution (1mm isotropic) diffusion MRI with high SNR and high b values.
