Image Guidance Modes
1.
Skull tracking
For intracranial treatment (e.g.: Brain metastasis)
Stereoscopic images compared with DRR library
2.
Spine tracking
For extracranial treatment with a fixed tumor to spine (e.g.: Spinal metastasis)
Stereoscopic images compared with DRRs (including deformable registration)
3.
Fiducial marker tracking
For extracranial treatment (e.g. Prostate)
Fiducial position extracted from stereoscopic images
4.
Synchrony
For tumors that move with respiration (e.g.: Lung ca)
Correspondence model between external markers and internal fiducials or
tumor in X-ray images
