Key Investigators

• Kitware: Brad Davis
• BWH: Sylvain Bouix

Objective

Our goal is to begin a validation study that will establish the accuracy and dependability of the Slicer3 EMSegment module. This objective is part of a larger, ongoing development effort for this module.

Approach, Plan

The validation study is based on a statistical comparison with results from earlier implementations of the EMSegment algorithm. The study will be carried out by members of the Psychiatry Neuroimiging Laboratory (PNL) at Brigham and Women's Hospital, on their data, using the newly developed command line version of the EMSegment algorithm. Kitware will provide software support and assist if problems arise with the results. Details are provided in the reference below. Our plan for the project week is to train the PNL staff on use of the new EMSegment tools, coordinate the validation study, and work out any bugs/interface problems as early as possible.

Progress

Preparations: develop EMSegment command line executable, add intensity normalization to module
