Agenda

Aim 2: Treatment planning

• Optimization is still in development. Issue with real-time. Doesn't necessary affect H Liu's task.
• 10-20 realistic cases from CT-guided RF retrospective analysis. BWH provides images, ???? segments as tumor as pre-processing. GW/GT run the cases. Gold standard GT physicians. GW take lead in publication.
  • BWH action item - obtain images from CT RF cases.
• Is milestone met? we are supposed to do 10 cases. We are on track.

Aim 2: Segmentation

• Sota presented on-line live demonstration of liver segmentation.
• Sota presented deformable registration methods in CTg liver/kidney.
  • parameter optimization
• tumor segmentation is not necessary.

• Not much work has been done for vessel segmentation. Ron strongly suggest VMTK for vessel segmentation.
  • [ Action Items for Sota] Sota will look into the usefulness of the vessel segmentation (VMTK) in Slicer during this trip.
  • S Aylward, looking into vessel segmentation.

Aim 3: System Integration

• H Liu presented status of Slicer interface for RF ablation
• H Liu will add manual needle planning to supplement "the automatic planning and optimization."
• Everyone agreed that we do a mock procedure using Slicer for planning and IGSTK for navigation.
• H Liu and Z Yaniv coordinate data exchange plan.
• Mock procedure to be done during summer.
• Accomplishment for this trip : Import/Export of the plan for navigation.
  • Design export/import method btwn Slicer/IGSTK navigation. VTK? DICOM? Planning ? trajectory? NRRD? What to be exchanged?
  • Initial implementation?
