SU-E-T-94: An Advanced Rotating Gamma Ray System for Stereotactic Radiosurgery

Purpose: Co‐60 beams have unique dosimetric properties that are ideally suited for cranial treatments. Co‐60 sources with cone‐shaped collimators provide conformal dose distributions allowing for ablative treatments with rapid dose falloff to spare nearby critical structures. This work investigates a novel, image‐guided, rotational Gamma ray system that provides both superior dose conformity/gradient and accurate stereotaxy for stereotactic...
