An O-space imaging gradient head insert was installed and the first in vivo head images were taken with the system. Field purity was of primary concern during design and implementation, and it was found via simulation that up to 10% deviation in field shape was acceptable given appropriate inclusion of the generated field during algebraic reconstruction. The O-space non-linear imaging system promises an attractive paradigm for future neuroimaging studies.
