2008 IGT Project Week RF Ablation System

Back to 2008_IGT_Project_Week#Projects

Team: Haiying Liu, Ziv Yaniv, Noby Hata, Paul Morrison

Goals: Create navigated RFA workflow based slicer module with stubs for all procedure steps:

1. Load CT data set.
2. Segment the volume using a semi-automatic approach (liver, tumor, ribs, blood vessels).
3. Manually denote regions as one of:
   1. Tumor
   2. Entry region
   3. No touch - RFA probe cannot pass or ablate this region.
   4. No pass - RFA probe cannot pass through this region but can ablate.
4. Export segmentation to planning module via text file.
5. Import plan into Slicer.
6. Manually localize fiducials.
7. Start IGSTK based tracking process.
8. Localize fiducials on patient and perform rigid registration.
9. Navigation GUI.

Approach: Implement during IGT and NAMIC project weeks.

Results:

1. Created an application to acquire tracking data:
   1. Use new xml parser
   2. Support multiple tracking devices
   3. Support broadcasting
2. Completed architecure for the RF ablation system
3. Completed workflow design for the system
4. Completed interface design in Slicer3
