NAV-RFA workflow and requirements

NAV-RFA Workflow

1. Place fiducials on patient.
2. Acquire volumetric data set, CT or cone-beam CT (corresponding modality DICOM tags are either CT or XA) at end expiration.
3. Segment the volume using a semi-automatic approach.
4. Enable manual segmentation to correct the semi-automatic results.
5. Export the segmentation to the planning module.
6. Import the plan back into 3D Slicer.
7. Start IGSTK based tracking process.
8. Localize fiducials on 3D data set.
9. Digitize fiducials using calibrated needle.
10. Perform rigid registration.
11. Show navigation GUI with current ablation path and target.
