Surface resonator for nuclear spin tomograph - consists of two partial systems with perpendicular magnetic fields, and currents 90 deg. out of phase

摘要

The surface resonator consists of two partial systems. The partial system magnetic fields (B11,. B12) are mutually perpendicular and their currents (I11, I12) are 90 deg. out of phase. Each partial system has at least one resonance capacitance and two current loops enclosing the associated magnetic field in the resonator plane perpendicular to the base field. The useful part of the field in the object region lies outside the resonator plane. USE/ADVANTAGE - Diagnostic arrangement produces stimulation pulses with HF field vector components only perpendicular to base field.
