Fetal brain surface atlas, weeks 21-36 of gestation, constructed using 242 in-utero scans from the fetal dHCP cohort.
The following surfaces were generated: pial, mid-thickness, white matter and very inflated. The maps of changes in cortical morphology - sulcal depth
, curvature
, and thickness
- are also available
Pictures of the white matter surface (right hemisphere) are here:
The template was generated by adapting the procedure developed for the neonatal surface atlas in Bozek et al. (2018 NeuroImage, 179, 11–29), which iteratively refines templates through a repeated alignment of individuals to a common space using the MSM algorithm. The first stage was to generate a common reference space, which was initialised via affine sulcal-depth-based registration to the dHCP neonatal GW36 template. From this, an initial set of age-specific templates was then generated through adaptive kernel-weighted averaging of co-registered surfaces, where weights were given by a Gaussian kernel, centered at each GW, with width adapted for each template to compensate for differences in the number of available scans. At subsequent 5 iterations, age-specific templates were obtained through non-rigid MSM alignment of all examples to the template from the previous iteration. This was driven by sulcal depth (for the 2nd iteration) and mean curvature thereafter.

| Description | This repository contains spatio-temporal surface atlas, spanning 21-36 weeks of gestation, generated by adapting the procedure developed for the neonatal surface atlas in Bozek et al., 2018, which iteratively refines templates through a repeated alignment of individuals to a common space using MSM algorithm to the fetal data. At each iteration, the age-specific templates are obtained through weighted averaging of co-registered surfaces, whereby weights are defined by the Gaussians centred on the gestational weeks for which templates are calculated, and are subsequently used as a target space for the following iteration. Adaptive kernel regression, compensating for a difference in the number of scans available for different ages, was used to parameterise the width of the Gaussians. The atlas was generated in three stages: first, a common reference space was initialised via affine sulcal-depth-based registration to the dHCP neonatal GW36 template. At the next iteration, the template was refined using sulcal-depth-based nonlinear alignment, followed by 4 iterations of curvature-based alignment (a more fine-grained feature than the sulcal depth). |
