Software for the fiber tracking and statistical analysis along the tracts has been implemented. The statistical methods for diffusion tensors are implemented as ITK code as part of the [[NA-MIC/Projects/Diffusion_Image_Analysis/DTI_Software_and_Algorithm_Infrastructure|DTI Software Infrastructure]] project. The methods have been validated on a repeated scan of a healthy individual. This work has been published as a conference paper (MICCAI 2005) and a journal version (MEDIA 2006). Our recent IPMI 2007 paper includes a nonparametric regression method for analyzing data along a fiber tract.

Objective

We are developing strategies to perform segmentation of a number of structures in the Head, Neck, and Thorax. Once segmentation is available, the goal is to register patient scans to account for anatomical changes between visits.




Approach, Plan

  • Get an accurate segmentation before beginning work on registration
  • First structure of interest is the mandible, by the end of the project week, obtain its segmentation
  • Come up with a strategy for segmenting the brain stem
  • Create an outline for further progress after the project week


Progress

  • Segmentation results are shown above.
  • We have three potential approaches to segmenting the brain stem to experiment with.
  • Created a complete data set for one patient including label maps for structures of interest.
