#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.
