0.55T MRI k-space datasets acquired from an ACR phantom: 2D spin-echo EPI with reversed phase-encoding directions + TSE

This repository contains raw MRI k-space datasets related to this paper: Cartesian MaxGIRF: Model-based EPI reconstruction incorporating gradient nonlinearity and concomitant field effects. Two fully sampled 2D SE-EPI datasets with reversed phase-encoding directions were acquired from the grid structure of the ACR phantom at 0.55T MRI (ramp-down 0.55T Aera). Imaging parameters were: (strict) coronal, FOV = 256 × 256 mm2, resolution = 2.0 × 2.0 mm2, slice thickness = 3 mm, 20 slices, fast mode, fat suppression, TE/TR = 149/4400 ms, FA = 90°, echo spacing = 1.06 ms, bandwidth = 1002 Hz/Px, no acceleration (R = 1), no partial Fourier sampling, ETL = 128, number of averages = 1, and PE directions = RL/LR (first/second).
