Key Investigators

  • BWH: Haiying Liu, Noby Hata, Sota Oguro
  • Georgetown University: Ziv Yaniv


  • Build a system for surgical planning and navigation to guide RF liver ablation.

Approach, Plan

The workflow reads as follows [after segmentation]:

  1. Export the segmentation to the planning program.
  2. Run the planning program.
  3. Load the plan specified in an xml file into Slicer for visualization and modification.
  4. User can view the plan. Ablations are overlayed onto the image slices. Ablation locations are from the xml file and the size of the sphere is already available in Slicer before step 1.
  5. User can move ablation locations.
  6. Export the modified plan.


  • Got tracking data from Aurora system using IGSTK
  • Can read surgical plan from an xml file
  • Can write surgical plan to an xml file
  • Working on visualization and modification of a surgical plan possibily using Measurements module

Delivery Mechanism

The work will be evolved as a Slicer module for surgical planning.
