Introduction (Gamma knife radiosurgery (GKS) is a non-invasive treatment option that uses focused beams of radiation to obliterate cerebral arteriovenous malformations (AVM). The role of the radiation therapy technician (RTT) in GKS is essential to the success of the treatment. Our objective was to explain the role of radiation therapy technologist (RTT) in radiotherapy treatment delivery.

Case Description (We retrospectively reviewed 160 patients who were treated with Gamma-Knife RS for intracranial AVMs between 14 March 2016. and 15 April 2024. There were 80 male and 80 female patients with a range of years 11- 74. Obliteration was assessed with MRI, MRI angiography and DSA imaging.

Results (Radiosurgery was successful in the majority of patients with minimal morbidity.

RTTs play a critical role in patient care, from the initial consultation to the follow-up appointment. They work closely with the radiation oncologist to develop the treatment plan and ensure that it is delivered safely and effectively. RTTs also provide emotional support to patients and their families throughout the treatment process. Their expertise, skill, and compassion are essential to the success of this treatment.
