Stereotactic Body Radiotherapy
SBRT has been used since 1990s.
Six main “requirements” (as of 2005):
Secure immobilization
Accurate repositioning of the patient from planning
to treatment
Accounting for internal motion (breathing)
Highly conformal dose distributions
Registration to stereotactic frame (?)
Few fractions, high doses
