Nuclear spin tomograph resonator - produces stimulation field with only HF field vector components perpendicular to base field using two partial systems

摘要

The nuclear spin tomograph resonator has a base field magnet with pole shoes between which is a measurement object's investigation region. The object's axes extend in the x and y coordinate directions. The resonator (10) consists of two partial systems rotated wrt. each other by 90 deg. and with resonator currents (I11, I12) mutually phase shifted by 90 deg. Each partial system is a current loop with a branch whose nodes are connected to a conducting ground plate (20) via resonance capacitances (24-27). ADVANTAGE - Nuclear resonance stimulation field has only HF field vector components perpendicular to base field.
