The human brain MR image is scanned by 1.5 Tesla GE-HDxt-MRI scanner with Gradient Echo (GE) sequence and 8 channels head coils with the specifications i.e. TE=10 msec, flip angle=900, bandwidth=31.25 KHz, slice thickness=3 mm, TR=55, and image dimensions=256×256 at St. Mary's Hospital, London, England.
Masks can be used in Fourier Domain to undersample the image.
