ASMR

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
