Objective

Traumatic brain injury (TBI) occurs when an external force traumatically injures the brain. It is a driving biological problem (DBP) in NA-MIC. TBI is a major cause of death and disability worldwide, especially in children and young adults.

We're working on the supervised segmentation and atlas optimization of longitudinal TBI data.

On anatomical MRI scans, to quantitatively analyze the cortical thickness, white matter changes, we need to have a good segmentation on TBI images. However, for TBI data, standard automated image analysis methods are not robust with respect to the TBI-related changes in image contrast, changes in brain shape, cranial fractures, white matter fiber alterations, and other signatures of head injury.


Approach, Plan

Our plan for the project week:

  • Test our preliminary code
  • Discuss with collaborators and try to refine the algorithm
