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 (committed to IGSTK cvs, will be part of the upcoming IGSTK release 4.0):
   1. Uses xml files to configure tracker type and configuration (specifying tools).
   2. Supports all tracking devices currently supported by IGSTK.
   3. Support broadcasting (specific request from Noby's colleagues in Japan).
   4. Currently program is command line and receives as input the xml file. Will work on a GUI for users that do not work with command line.
2. Completed architecure for the RF ablation system.
3. Completed workflow design for the system.
