4D multi-channel neonatal brain altas

---

This repository contains a 4D parametrized atlas multi-channel atlas of the normal term neonatal brain development during 37-44 weeks PMA presented in (Uus et al., 2021). The atlas was constructed from 170 normal term MRI datasets from the dHCP project.

The atlas includes:

• 4D fitted structural MRI channels (common 0.75mm and unbiased 0.6mm space): T1w, T2w, T1w/T2w
  
• 4D fitted diffusion MRI channels (common 0.75mm and unbiased 0.6mm space): DTI(FA, MD, RD), ODF(ODF, TDI), NODDI(FICVF, FISO, ODI), average DWI, DKI(MK), microFA
• parcellation maps (M-CRIB-WM-based WM ROIs, high rate change "gamma" ROIs and the original dHCP tissue ROIs)
• Gompertz model gamma maps (outputs of 4D fitting corresponding to the signal change rate in time)
• transformations from 37 to 44 weeks PMA timepoints (affine in MIRTK format and nonlinear warps in MRtrix3 format)
