In
order to address the need of the MR coil with both high field strength and
low power usage, a miniaturized B0 coil is presented. Finite element
simulation showed that higher magnetic field strength was generated by a coil
with sharp tip than that by a coil with blunt end. A cost effective way was
introduced to fabricate this sharp tip coil. Focused magnetic field generated
by the coil with a sharp tip was directly measured by a tunneling effect
magnetic field sensor. This study will help in addressing the need of
portable MR systems.
