The purpose of the study is to present an end-to-end experimental procedure, based on a polymer gel phantom, capable of assessing the total geometric uncertainty in GK radiosurgery applications, in which MR images are solely used for both target delineation and registration of patient image coordinates to the Leksell space. As a result the study aims to propose a time-efficient method, based on corresponding polymer gel results, which considerably improves the geometric accuracy in GK treatment delivery.
