A symmetric, folded gradient, was designed for human
brain imaging, with a target gradient strength of 80
mT/m and slew rate of 2900 mT/m/s. This design should
limit forces and torques leading to a quieter coil with
better eddy-current performance. The ultra-short design
allows for human brain imaging without the need for
shoulder cut-outs. The insertable coil was built using
litz wire for transverse axes and hollow copper for Z to
facilitate cooling. It was successfully interfaced with
a clinical scanner and its electrical and imaging
performance was characterised.
