Non-linear Realignment Using Minimum Deformation Averaging for Single-subject fMRI at Ultra-high Field

Motion dominates the contribution to variance in fMRI time series and it is therefore important to account for this variability correctly. Currently, most correction schemes use a rigid body realignment procedure, but interactions with magnetic field inhomogeneities and physiological fluctuations lead to non-linear deformations. Non-linear realignment increased spatial resolution by Read more…

Ultrashort echo time imaging using pointwise encoding time reduction with radial acquisition (PETRA) average 7T model

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