Robust Susceptibility-Matched NMR Probes for Compensation of Gradient Field Imperfections in Magnetic Resonance Imaging

A sensor system has been implemented to measure magnetic field imperfections in Magnetic Resonance Imaging (MRI). For this purpose, a novel method to manufacture Nuclear Magnetic Resonance (NMR) probes has been developed. Casting the NMR signal source and the sensing coil directly into paramagnetically doped epoxy drastically simplifies the manufacturing process. The design of NMR-probes with long acquisition time, and high signal-to-noise ratio (SNR) is presented and the optimization of the susceptibility for epoxy is described. To verify the functionality of the probe design, experimental results for the sensor-assisted acquisition of MR images are presented.
