V1-V5 - Raw Data - Motion-resolved fat fraction mapping with whole-heart free-running multiecho GRE

(PART 1) whole-heart cardiac MRI datasets from healthy volunteers (1.5T)

Each folder labelled V1-V5 contains:

1) Free-running multiecho GRE (NTE=8) raw data file

2) ECG-triggered multiecho GRE (NTE=5) raw data file

3) Matlab file "PhysioInfo.mat" containing the physiological signal information (Pilot Tone raw data, extracted respiratory signal, extracted cardiac signal, extracted cardiac trigger points, and corresponding time stamps).

PART 2 can be found at: https://zenodo.org/record/7615780#.Y-TJoHbMLcs

Matlab code to load the raw data, compute the 3D trajectory and read the raw and extracted Pilot Tone signals is available at:
