probes is need it for high resolution Magnetic Field
Monitoring (MFM) but it compromises the SNR and the
manufacturing process becomes more challenging. We
introduce a new design of field monitoring probes
consisting in a solenoid placed directly into the sample
material, here called, sample-immersed microcoil (SIM)
probes having a high-impedance RF shield to avoid eddy
currents. We validate this design experimentally in
terms of sensitivity, SNR, internal homogeneity and RF
shielding efficiency. We observed that this design give
us long duration signals without significant SNR losses
that could allow us to monitor imaging sequences having
resolutions below 200
m.
