Reduced field of view (rFOV) technique has been known for its advance in shortening the read-out train in MR imaging. With this excitation scheme, high resolution Echo Planar Imaging (EPI) becomes available with less geometric distortion. In this work, a multiple slice rFOV sequence was proposed with multiple sequential volume acquisition to combine the rFOV images as a full FOV image with appropriate intensity correction to compensate the effect of RF profile imperfection during excitation. And a high resolution in vivo EP-DTI dataset with tractography result was demonstrated to confirm the feasibility of this proposed scheme on clinical research.
