Outline of Final Research Achievements

The purpose of the present work was developing a compact low field magnetic resonance imaging (MRI) system running　on a same magnetic circuit used for a 750 MHz CW electron paramagnetic resonance imaging (EPRI) system. A current source to drive a high inductance gradient coil of ~ a few mH with the response time of ~ 50 us was developed. We demonstrated that nuclear magnetic resonance (NMR) signal acquisition was possible without the interference of an EPR probe by setting a NMR probe located outside the EPR probe. Low field EPR/NMR co-imaging of a test sample was succeeded using the same magnetic circuit without moving the sample.
