Instance 3 : First repeat imaging visit (2019+)
4,490 participants, 4,490 items
Data not meaningful for statistical summary
The source DICOM images were acquired using the following parameters:
Resolution: 0.8x0.8x3 mm
Field-of-view: 256x288x48 matrix
Duration: 2.5 minutes
Two echos, TE=9.42,20 ms
2D, axial, in-plane acceleration iPAT=2, partial Fourier = 7/8, prescan-normalise
To date (Oct 2015) the magnitude and phase images have been saved for each RF coil and echo time separately. In future the expectation is to combine these on the scanner.
The average size of these NIFTI datasets is 35MB per participant.
