Simple robust estimation of gradient delays for spiral MRI
OBJECTIVE: Spiral MRI image quality is degraded by timing misalignments between gradient transmission and data sampling. Even well compensated and calibrated MRI scanners can experience residual, sequence specific gradient delays. Several methods exist for measuring and correcting for deviations in the k-space trajectory. This work proposes a simple, fast method for measuring gradient delays at...
متن کاملSimple Method for Adaptive Gradient-Delay Compensation in Radial MRI
Introduction: Radial sampling of k-space has gained strong interest over the past years due to inherent advantages such as lower sensitivity to motion and flow artifacts, continuous coverage of the k-space center information, and the absence of any ghosting artifacts. Further, because undersampling for radial trajectories leads to incoherent streaking artifacts instead of discrete aliasing, rad...
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 quantum algorithm for numerical gradient estimation.
Given a black box for f, a smooth real scalar function of d real variables, one wants to estimate [symbol: see text]f at a given point with n bits of precision. On a classical computer this requires a minimum of d + 1 black box queries, whereas on a quantum computer it requires only one query regardless of d. The number of bits of precision to which f must be evaluated matches the classical req...
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...
