< 1 milimeter for stationary tumours < 1.5 millimeters for moving tumours intracranial and extracranial
Ability to fractionate
Typically limited to a single fraction due to time resource and pain constraints.
None. Relies exclusively on target's fixed relative position to the stereotactic frame mechanical accuracy.May introduce 1.2-1.9 mm error (Maciunas).
Continual image guidance through the treatment high resolution kv imaging automatically track, detect and correct for tumour and patient movement.
Non-coplanar delivery capabilities
Hemisphere with fixed collimators enables a non-coplanar workspace capable of delivering a maximumof 201 (190 perfexion) unique beam angles.
Robotic mobility enables a large non-coplanar workspace capable of seamlessly delivering more than 1200 unique beam angles without treatment interruption or the need to manually reposition the patient.
Moving tumour targeting
Delivery, tightly contoured beams synchronised precisely to tumour motion, resulting in minimal healthy tissue exposure.
