Concomitant gradient field effects in spiral scans.
Maxwell's equations imply that imaging gradients are accompanied by higher order spatially varying fields (concomitant fields) that can cause artifacts in MR imaging. The lowest order concomitant fields depend quadratically on the imaging gradient amplitude and inversely on the static field strength. Time-varying concomitant fields that accompany the readout gradients of spiral scans cause unwa...
متن کاملFast Concomitant Gradient Field Correction for Spiral Scans
Introduction: A major drawback to non-Cartesian imaging is the off-resonance blurring effects. Common linear techniques that remove the distortion effects are not sufficient, because the high order concomitant gradient fields are nontrivial for low fields and for scans that are more than 5 cm off isocenter [1]. Previous correction algorithms either are slow or do not take into account the known...
متن کاملFast Field Inhomogeneity and Concomitant Gradient Field Correction in Spiral Cardiac Imaging
Introduction: Cardiac imaging, for both real-time and triggered imaging, requires a high data acquisition rate. Spiral trajectories achieve this rate; however, their advantages are shadowed by off-resonance blurring and distortion effects. Current techniques to correct for this image degradation do not easily or quickly account for the different effects specifically field inhomogeneities and co...
متن کاملFast 3D EPR Imaging Using Spiral Magnetic Field Gradient
We report a fast 3D continuous wave (CW) electron paramagnetic resonance imaging (EPRI) technique using spiral magnetic field gradient. By spiraling the magnetic field gradient and stepping the main magnetic field, this approach acquired a 3D image in one sweep of the main magnetic field, enabling significant reduction of the imaging time. We demonstrated using a home-built L-band EPR system th...
متن کاملElectric field gradient effects in raman spectroscopy.
Raman spectra of materials subject to strong electric field gradients, such as those present near a metal surface, can show significantly altered selection rules. We describe a new mechanism by which the field gradients can produce Raman-like lines. We develop a theoretical model for this "gradient-field Raman" effect, discuss selection rules, and compare to other mechanisms that produce Raman-...
