Buonocore, M. H. & Gao, L. Ghost artifact reduction for echo planar imaging using image phase correction.

Image phase from gradient echo MRI provides a unique contrast that reflects brain tissue composition variations, such as iron and myelin distribution.

To address these two issues, a SNR optimized multi-echo sequence with a stack-of-spiral acquisition is proposed and implemented for achieving fast and simultaneous acquisition of image phase and T2* maps.

This article presents a novel method for bone segmentation from three-dimensional (3-D) ultrasound images that derives intensity-invariant 3-D local image phase measures that are then employed for extracting ridge-like features similar to those that occur at soft tissue/bone interfaces.

Similar results were calculated using the image phase, to mimic the use of the referenceless method.

The phase shift image (phase plate) was calculated from the measured aberrations for the DCOR.

Based on the sign map, single image phase-extracting methods such as quadrature transform can be improved.

CTF determination and correction of image phases were carried out in Appion using Ace2 (NRAMM).

Multiplication of the Fourier transform of the image by the CTF corrects the image phases, while division by CTF + 1/ SNR) provides the amplitude correction.

The simplest method of CTF correction is to flip the image phases in regions of the spectra where sin γ reverses its sign.
