Qualitative Inquiry, 2018
This article is an autoethnodrama that explores the reminiscences by two authors’ immigration experiences as an international student and the dependent spouse. The story we will tell evokes how immigrant students’ adjustment requires an endless border-crossing that exists in geographical, cultural, and everyday-life levels.

The Ghost as Artist. Allusive Echoes in The Canterville Ghost
2021Originariamente pubblicato su “The Court and Society Review” in due puntate (febbraio-marzo 1887) e in seguito incluso nella raccolta “Lord Arthur Savile’s Crime and Other Stories” (1891), “The Canterville Ghost” fu il primo racconto edito di Oscar Wilde.

Ghost artifact reduction for echo planar imaging using image phase correction
Magnetic Resonance in Medicine, 1997AbstractAn algorithm is described for reducing ghost artifacts in echo planar imaging (EPI) using phase corrections derived from images reconstructed using only even or odd k‐space lines. The N/2 ghost, that arises principally from time‐reversal of alternate k‐space lines, was significantly reduced by this algorithm without the need for a calibration ...

Reduction of phase error ghosting artifacts in thin slice fast spin‐echo imaging
Magnetic Resonance in Medicine, 1995AbstractFast spin‐echo (FSE) imaging techniques are very sensitive to the relative phase between the 90° (excitation) RF pulse and the 180° (refocusing) RF pulses. In this paper, it is demonstrated that a phase shift can be created between the excitation and refocusing pulses in such a manner that the received signal is divided into two components of ...

ISMRM Annual Meeting, 2023
We propose a new correction scheme using a deep neural network with unsupervised learning to correct Nyquist ghosts and geometry distortions occurring in EPI. The proposed scheme includes NGAC-net and GDC-net. First, the NGAC-net estimates the phase error of k-space with the help of a ghost formulation operator and correlation loss.

Ghost artifact on gradient-echo imaging: a potential pitfall in hepatic imaging.
American Journal of Roentgenology, 1990Standard evaluation of the liver with MR uses spin-echo imaging with Tiand T2-weighted pulse sequences [1]. A short inversion-time inversion recovery (STIR) sequence has been used as an adjunct to standard pulse sequences because it provides certain advantages, including fat suppression, additive effects of Ti and T2 relaxation on tissue brightening ...
