Reduced field of view (rFOV) imaging offers several advantages, including high spatial resolution and reduced image distortion. We propose an in-plane simultaneous multi-segment (IP-SMS) imaging method to extend the benefits of rFOV to full FOV imaging. Unlike the conventional simultaneous multi-slice imaging, IP-SMS performs in-plane simultaneous multi-segment excitation by utilizing the periodic replicas of excitation profile of a 2D RF pulse, followed by parallel segment reconstruction using a set of “virtual” coil sensitivity profiles. We have demonstrated the IP-SMS imaging technique on phantoms and human brains where high-resolution diffusion images were obtained with minimal distortion.
