Objective
We are developing a Slicer module for population analysis. The module will take as an input a file with all the files needed for a population analysis. Actually all the files will be download with FetchMI from XNAT.
Approach, Plan
Our approach Our plan for the project week is to first try out to download not only A MRML scene but any file we need. Then retreive this files and send them to another module for processing. <bar>,...
Progress
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 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.
