ChangeTracker

Overview

THIS PAGE IS UNDER CONSTRUCTION -- CHECK BACK OFTEN!

ChangeTracker is a 3D Slicer GUI module for monitoring slowly evolving tumors. This page will host the relevant information about ChangeTracker.

What's New

• Nov 21, 2008, ChangeTracker now uses Linear registration command module for rigid registration.

User information / Tutorials

• Detecting subtle change in pathology: slides, data

Bugs / Known issues

• during "Analysis type step", Slicer crashes if "Analyze" button is hit more than once
• registration of a new volume node with the scene results in update of the slice views
• incorrect setting of the registration parameters results in registration producing empty volume, no error messages from the module: Current implementation of CommandLineModule does not evaluate return value from the module entry point. Module error handling needs to be re-examined. Posted request to slicer-devel
• need to investigate reproducibility of registration and impact of the random seed initialization: Linear registration updated with metric seed reinitialization
• investigate reasons for segfault with the weird dataset from Yanling
• check and clean up file output procedures (..-TG directories)

Feature requests/Features under development

• multi-color volume rendering for tumor growth results
• use Compare view
• 3d box widget for ROI selection
• analysis of multiple time points
• testing
