For the ISMRM 2016 we build a minimum deformation average (MDA) from a population of subjects based upon high resolution 7T MR imaging.

Acquisition details

MP2RAGE: 48 (16 female, 31.1±8.6yr) individuals were imaged using a prototype MP2RAGE sequence with a range of resolutions: 0.5mm (18 indiv.), 0.75mm (21), 1.0mm (8) and 1.3mm (1). TR= 4330ms, TI1/TI2=750/2370ms, TE=2.8ms, flip angle=5,6, and GRAPPA = 3. The image matrix was typically 256x300x320 or 420x378x288 but was dependent upon coverage and FOV. The MP2RAGE denoised images [6, 7] were intensity-normalised using a histogram clamping technique.
