โœฆ Synopsis

Abstract

Viewโ€toโ€view phase shifts due to B0 instability are corrected by applying a phase correction to the lowโ€spatialโ€frequency views. The algorithm described herein assumes that the signal intensity in the space outside of an object represents only noise. A set of phases for the lowโ€spatialโ€frequency views are calculated by minimizing, in the image, the intensity of the induced artifacts in the space outside of the object.

By making use of the phase information in the image data, the proposed method can overcome the data inconsistency prob

In in-vivo applications of proton NMR spectroscopic imaging, an oscillatory "ringing" artifact has been observed in some of the spectra. The source of this artifact was found to be the presence of a harmonic "beating" effect in the amplitude of the water reference free induction decay (FID) which wa

## Abstract One of the most common artifacts for echoโ€planar imaging is the Nyquist ghost, typically overcome with the aid of a reference scan preceding the actual image acquisition. In this work, a nonlinear phase correction obviating the need for a reference scan is proposed. The method is based

## Abstract This work describes the method of generalized projections (MGP) as an imageโ€based, postprocessing method to correct for phase inconsistencies caused by echo misalignments in radial imaging. Computer simulations show that MGP can correct for echo shifts, constant phase, and amplitude err
