Many magnetic resonance imagers operate at a magnetic field strength of 1.5 Tesla. A few research units operate at 4.7 Tesla.
What is the resonance frequency of the following nuclei in each of the magnetic fields?
1H
23Na
31P
ν = γBo
where:
ν = resonance frequency
γ = gymagnetic ratio for the nuclei in question
Bo = magnetic field strength
