Electron paramagnetic resonance imaging device using microwave bridge translator

摘要

A device is described which permits the acquisition of Electron Paramagnetic Resonance Images without employing additional hardware for generation of magnetic field gradients. It incorporates a module 33 for translation of the bridge-circulator-resonator-detector assembly in order to locate the resonator 25 at an optimal off-center position in the magnet 32 and employs the inherent gradient in the magnetic field, permitting operation with gradients of 5 T m-1 or higher, in continuous wave or pulsed mode.
