Phase-contrast magnetic resonance imaging (MRI) is used to image particle displacements arising from a 0.515-MHZ focused ultrasound (US) field. The technique used a phase-locked, self-resonant gradient matched to the US frequency in conjunction with a spin-echo sequence to generate phase images of U

β¦ Synopsis
A novel X-band CW EPR imaging has been developed using magnetic-field-gradient (MFG) spinning to obtain spatial distributions of electron paramagnetic species. Spinning MFG EPR imaging for 65 projection spectra required just 55 s while conventional imaging took 11 min 40 s, that is, the acquisition time for the new system is one order of magnitude shorter than that for conventional EPR imaging. Spinning MFG EPR imaging allows one to measure reconstructed images in an interactive manner where resolution and condition can be changed quickly. Copyright 2000 Academic Press.

## Abstract Continuous wave (CW) electron paramagnetic resonance (EPR) imaging can be used to obtain sliceβselective images of free radicals without measuring threeβdimensional (3D) projection data. A method that incorporated a modulated magnetic field gradient (MFG) was combined with polar field g
