We are developing methods for segmentation of white matter hyperintensity in FLAIR images of stroke patients. Specifically, WMH is to be localized in particular areas of the brain, as seen in a training set. This dataset is particularly challenging due to the low resolution (1mm x 1mm x 7mm) and with cropped fields of view in the given images.

Project Description

Objective

We want to explore a imaging genetics model and identify (potentially continuous) phenotypes in stroke patients. Combined with the WMH segmentation, we will start with WMH-based imaging phenotypes.

Approach, Plan

  • Run through the WMH pipeline.
  • Construct distribution map of WMH
  • Explore clustering of WMH
  • Explore current imaging genetics model developed in our lab with above phenotypes and stroke dataset genotypes.
