One primary factor limiting the extension of electron paramagnetic resonance imaging (EPRI) beyond small animal applications is the challenge of create uniform RF fields at the higher RF frequencies needed to achieve the desired sensitivity. In this abstract, we discuss the development of a traveling-wave spectrometer operating in continuous-wave mode at 115 MHz. The spectrometer uses a parallel-plate waveguide supporting transverse electromagnetic waves to create a uniform transmit field and uses a conventional receive coil. We demonstrate the feasibility of a traveling wave system and its potential to be developed into an EPR imaging system.
