Scintillating phantom offers CyberKnife QA

Stereotactic radiosurgery – the highly targeted delivery of large radiation doses over a small number of treatment fractions – requires incredibly tight tolerances on tumour localization and patient positioning. As such, the geometric and dosimetric accuracy of a stereotactic radiosurgery system must be precisely verified and maintained, with robust quality assurance (QA) procedures performed on a regular basis.
