A dedicated head-only gradient set with asymmetric
transverse coils and a hollow-conductor z coil was built
and tested. The coil incorporated force-balanced,
torque-balanced, and eddy current-controlled design. The
coil was tested inside a conventional whole-body 3T
magnet to assess image quality and peripheral nerve
stimulation (PNS). The gradient was integrated with a
custom-built birdcage transmit/receive coil and a
32-channel receiver array for in-vivo imaging. Initial
results demonstrated high quality brain images with
transverse gradients at 80 mT/m and 500 T/m/s
(simultaneously) without PNS.
