Artifact Correction for Echo-Planar Imaging at Low-Field and Ultra-Low-Field MRI 事件

Artifact Correction for Echo-Planar Imaging at Low-Field and Ultra-Low-Field MRI arXiv:2605.25589v1 Announce Type: new Abstract: Purpose: Echo-planar imaging (EPI) in low-field (LF) and ultra-low-field MRI (ULF) suffers from severe Nyquist ghost artifacts due to odd-even k-space misalignment. This study develops a reference-free artifact correction pipeline that reduces reliance on conventional reference scans while achieving improved ghost suppression. Methods: Starting from the traditional re
