Preprocesing steps and atlas based brain tissue segmentation. (a) Raw 0.35 T T2WI from a representative patient. (b) N4 bias field corrected image. (c) manual segmentation of brain parenchyma and segmented image in (d). (f–h) Registration from patient individual space to template space in three steps: rigid (h), affine (g), SyN (f). Red dashed line depicts the contour of template (e). The inverse transformed template (i) and corresponding tissue probability maps (j). (k) Whole brain segmentation estimated by EM.
