Turbo Spin Echo (TSE) T2-weighted 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.

Acquisition details

TSE: 26 (13 female, average age 26.8±3.9) individuals were imaged using 3 repetitions of a 2D Turbo Spin Echo (TSE) sequence covering a slab orthogonally to the axis of the hippocampus with a resolution of 0.2×0.2×0.8mm, flip angle 134, TR 10.3s. Before the atlas creation, we averaged the three TSE acquisitions per participant to one dataset to increase SNR and reduce the amount of data to be processed. Then we resampled the TSE data to an isotropic voxel size of 0.4 mm.
