We propose a method to predict B1 filed using coil
geometry and location in imaging coordinate system
without doing B1 mapping. Most of B1 mapping are done
without any assumption about the coil geometry and
location. Coils location are found by placing markers on
coil conductors, then by acquiring three sets of 1D
projections to localize the markers ,coil plane can be
detected. Having known the coil location and geometry,
B1 field distribution can be obtained by computational
analysis .To validate the method, we compare simulated
with measured results. Field prediction can be used in
auto-calibration and RF pulse design.
