Key Investigators

  • Peter Karasev, Ivan Kolesov : Georgia Institute of Technology
  • Karl Fritscher : BWH at Harvard and UMIT (Austria)
  • Allen Tannenbaum : Boston University

Objective

  • Goal: Improve the usability (speed, visualization, resource management) of the KSlice interactive segmentation algorithm.
  • Determine suggested energies to be used on different modalities/anatomic structures


Approach, Plan

  • Test the algorithm on more data sets (so far, experiments on orthopedic MRI and limited CT datasets have been performed)
  • Experiment different energies on different modalities.
  • Reduce the memory consumption for multiple label maps.
  • Allow new users (you!) to try the algorithm on your data sets (to obtain feedback on its usability).

Progress

  • Successfully segment some TBI and AF images on first try. TBI works great, AF a bit less so due to the region-based nominal dynamics.
  • Profile with valgrind the bottlenecks in 3D application.
  • Generate some synthetic 3D test data to best align matlab and c++ codes' testing.

Delivery Mechanism

This work will be delivered to the NA-MIC Kit as a

  1. Slicer Module (via PLUS and OpenIGTLink)
