Evaluation of the setup margins for cone beam computed tomography–guided cranial radiosurgery: A phantom study

Abstract The aim of this study is to evaluate the setup margins from the clinical target volume (CTV) to planning target volume (PTV) for cranial stereotactic radiosurgery (SRS) treatments guided by cone beam computed tomography (CBCT). We designed an end-to-end (E2E) test using a skull phantom with...
