Ghosts in the Consulting Room: Echoes of Trauma in Psychoanalysis
Transactional Analysis Journal, 2018“What is it, then, that determines whether the conflicted past of the parent will be repeated with his child?” (Fraiberg, Adelson, & Shapiro, 1975, p. 419).

Reference-free Correction for the Nyquist Ghost in Echo-planar Imaging using Deep Learning
Proceedings of the 2019 6th International Conference on Biomedical and Bioinformatics Engineering, 2019Echo-planar imaging suffers from Nyquist ghost (i.e., N/2 ghost) because of the imperfection of the gradient system and gradient delays. The phase mismatch between even and odd echoes can be eliminated by an extra reference scan without the phase encoding.

A Portrait of the Artist as a Ghost: Joycean Echoes in Philip Roth’s Depiction of the Artist
Philip Roth Studies, 2023Abstract: This essay traces the origin of the ghost’s metaphor in Philip Roth’s The Ghost Writer (1979) and argues that, under the influence of James Joyce, Roth molds his poetics through his most famous fictional double and his artistic journey. At the same time, he shapes an authorial figure that questions the act of writing in the twentieth century.

Magnetic Resonance in Medicine, 1993
AbstractPulsation artifact on gradient echo images with ultrashort TE (i.e., <3 msec) and intermediate TR is primarily from view‐to‐view amplitude modulation. Paramagnetic contrast agents increase the signal from blood during diastole without increasing the intensity of unsaturated systolic blood, decreasing signal modulation between systole and ...

Echo-planar spectroscopic imaging with flyback readout: ghost peaks and micro-imaging
ISMRM Annual MeetingMotivation: To assess echo-planar spectroscopic imaging (EPSI) with flyback readout gradients in preclinical MR system. Goal(s): To demonstrate spectral ghost artifacts produced by two, three, and four interleaved gradient echo trains and to measure water, fat, and water-fat shift artifacts free images.

3D Dual-Polarity GRAPPA for Ghost Correction of Volumetric Echo-Planar Imaging Data
ISMRM Annual MeetingMotivation: 3D-EPI suffers from inherent sampling errors, similar to conventional 2D-EPI, which result in Nyquist ghosting and shading artifacts that arise from non-linear phase errors in the sampled data. Goal(s): To demonstrate that the Dual-Polarity GRAPPA (DPG) reconstruction method can be extended and applied effectively to 3D-EPI data.
