32 channel ge receive only head coil

Data were acquired on a GE MR750 3T scanner using a 32-channel GE receive-only head coil (Waukesha, WI). Each imaging session first involved acquiring a whole-brain anatomical MPRAGE scan with 1mm isotropic resolution. The resting state fMRI scan was 10 min long and involved acquisition with multi-echo time course EPI using the following parameters: 240mm field of view (FOV), 64×64 matrix size yielding 3.75mm isotropic resolution, in-plane SENSE acceleration factor 2, flip angle (FA)=77 degrees, repetition time (TR)=2.0s, and echo times (TEs)=12.8,28,43ms. The multi-echo fMRI sequence utilized vendor EPI excitation and a modified EPI readout, and utilized online reconstruction. Each TR resulted in the acquisition of 3 volumes, one for each TE. These volumes are rearranged to yield one volumetric time series dataset for each TE.

fMRI data were acquired using a General Electric (GE) 750x scanner
(Waukesha, WI). The scanner’s body coil was used for RF transmission. A
32-channel GE receive-only head coil was used for signal reception. A
T₁-weigted anatomical image and a proton density-weighted
anatomical image were acquired for each participant using an MP-RAGE sequence
(192 Axial slices per volume, slice thickness = 1mm, FOV =
256×256 mm, image matrix = 256×256). This was followed
by a high-order shim and an ASSET calibration. Task data were acquired using a
multi-echo echo-planar imaging (EPI) sequence with echo times at 14.6, 26.8, and
39.0 ms (TR = 2 s, voxel size = 3×3×3.5 mm,
image matrix = 72×72, FOV = 21.6×21.6 cm, slice
thickness = 3.5mm, slice spacing = 0.0mm, flip angle =
77 deg, 37 oblique slices, 252 acquisitions per run, ASSET acceleration
= 3).
