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


===Additional comments===
#Needle calibration - requires implementation in IGSTK.
#Interaction with planning/optimization module should be done using an xml file format.
#Setup of the tracker process should be performed using an xml file. This should be output provided by Slicer.
The XML file will contain:
#ip address to which we write data.
#All communication settings required for the Aurora (COM port, baud rate, etc.).
#For each tool:
##The desired ip and port to which the data should be written.
##The physical port on the control box that corresponds to this tool.
##Optional, the physical channel on the port 
##Optional, the SROM file for the tool. 
  
#Expected GUI: 
##Axial, off axial, off sagittal, and down the barrel views (see [http://public.kitware.com/IGSTKWIKI/index.php/ImageSliceRepresentation#Appendix this] page for definitions). 
##Axial, off-axial and sagittal views display the planned trajectory and the needle projection. 
##Down-the-barrel view displays concentric circles denoting needle tip hub and target. In addition a depth gauge displaying the distance from the target.
##Respiratory signal as estimated from tracking data.
##Allow user to choose each trajectory and show ablation targets starting with the one farthest from the entry point along the trajectory.
