Abstract

Resolution in functional imaging can be increased by limiting the Field of View (FOV) for the image, increased acceleration and faster imaging using specialized gradient systems. Here we combine the high performance gradients of the NexGen 7T scanner with limited FOV imaging to collect ultra-high resolution fMRI in the occipital pole. Isotropic resolutions of 0.35mm are demonstrated using 3D EPI.
