Objective

We are aiming to develop Quality Control (QC) procedures for Diffusion Weighted Imaging such that the artifacts are detected and corrected. The QC procedures are implemented in the open source tool DTIPrep and includes

Approach, Plan

Update the NITRC media wiki pages for DTIPrep to match the current version of the program. Use the updated wiki as a basis for a tutorial. Coordinate efforts with Cheryl Dietrich at UNC.

Progress

A detailed pdf on DTIPrep documentation has been uploaded from UNC. Work has started on creating a NAMIC-style ppt tutorial and will be completed soon. This tutorial will be submitted for the June tutorial contest.
