Abstract 

The dataset can be used for Brain MRI study for academic purpose only. Undersampling Masks can be used for random undersampling at different sampling rates. 

Instructions: 

Acknowledgement of source is required.

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.
