Diffusion Tensor Imaging fiber tracking requires parameter tuning. This study introduces a visualization tool to explore parameter variations, enhancing result reliability and reproducibility for brain white matter analysis.

Area of Science:

  • Neuroimaging
  • Computational Neuroscience
  • Medical Image Analysis

Background:

  • Diffusion Tensor Imaging (DTI) fiber tracking visualizes brain white matter organization.
  • DTI fiber tracking algorithms are sensitive to user-defined input parameters, impacting results.
  • Current methods lack evaluation of parameter stability and reproducibility across users.

Purpose of the Study:

  • To develop a visualization tool for exploring the impact of parameter variations in DTI fiber tracking.
  • To enable users to assess the stability of tracking parameters and improve inter-patient result reliability.

Main Methods:

  • Development of an interactive visualization tool.
  • Visual exploration of how minor parameter changes affect fiber tracking output.
