Structural preprocessing

Structural processing

What is it about?

Several steps to obtain a segmented brain with possibility to create surfaces

Issues specific to NHP imaging

• non standard orientation: sphinx position, oblique orientation

- strong intensity bias due to a huge variety of coils used

- large FOV / non brain tissue

Steps

Preparation of data (Cropping, deoblique…)

• What is is about?

• Solutions

Registration to template

Brain extraction / skull stripping

Segmentation (GM, WM, CSF? Subcortical?bone, non brain soft tissue? air?)

Surface generation

Morphometry measures (thickness, curvature etc)
