  • Isomics: Steve Pieper

Objective

We would like to create end-to-end applications within Slicer3 allowing individual and group analysis of regional (voxel-based) and local (mesh-based) cortical thickness.

Such a workflow applied to the young brain (2-4 years old) is our goal in order to start a longitudinal study of early brain development in autism (UNC DBP).

See our Roadmap for more details.

Approach, Plan

Our approach is described in the following wiki pages:

Our plan for the project week is to follow-up on the local cortical thickness pipeline and apply it to a small pediatric dataset.


Progress

NITRC:


ARCTIC:

  • Source code updated
  • Works again as a Slicer3 extension module


Population analysis:

  • Meetings with Wendy Plesniak, Daniel Marcus, Timothy Olsen, John Paulett, Steve Pieper, Julien Jomier, Martin Styner, Corentin Hamel
  • Better understanding of how population analysis could be performed within Slicer3, using BatchMake and XNAT


Mesh based cortical thickness pipeline:

  • Meeting with Josh Cates and Martin Styner regarding particle correspondence (usage and future options)
  • Applying individual pipeline to small pediatric dataset
