RF
coil arrays are critically important for hyperpolarized C-13 imaging because of
increased sensitivity, coverage, and speed. A major limitation preventing
widespread use of coil arrays is the difficulty measuring coil sensitivity
profiles due to low C-13 natural abundance. We propose to solve this problem by
using fiducial markers filled with 55Mn to determine coil location and then
calculate coil sensitivities. We show proof-of-principle using a single RF coil
and ethylene glycol phantom. Coil sensitivties derived from fiducial markers
and quasitstatic calculations closely match those acquired through experiment.
