Abstract
Spin resonance spectroscopy and/or imaging is achieved using a system that combines longitudinal (e.g., along the z-axis) detection with a modulated fictitious field generated by a transverse plane (e.g., xy-plane) RF field. Based on z-axis detection of magnetization polarized by this fictitious field as it is modulated (e.g., modulated on and off, or otherwise), spin resonance signals (e.g., EPR, NMR) are measurable with high isolation simultaneous transmit and receive capability. Additionally or alternatively, spin relaxation times can be measured using the described systems.
