Gamma Knife is a stereotactic radiosurgery (SRS) instrument using Cobalt-60 radiation sources to treat malign and benign brain tumours and other skull base disorders. With the introduction of inverse radiation planning, which has recently been adopted in Gamma Knife treatment, dose verification is recommended for Gamma Knife radiosurgery. Such plan verification is already standard practice for other teletherapies. For plan verification in Gamma Knife therapy, a new SRS phantom based on film dosimetry and an end-to-end verification protocol has been developed and implemented. The gamma analysis is used to evaluate the conformance between the measured dose distribution and the dose distribution calculated by the radiation planning system. The focus of this lecture is on the adaptations of the standardized plan verification method to stereotaxy and the associated challenges such as the small target volumes and the high applied dose, which demand high accuracy.
