[HTML][HTML] Setup accuracy in craniospinal irradiation: implications for planning treatment volume margins
Purpose Craniospinal irradiation (CSI) using tomotherapy has advantages over standard 3-
dimensional techniques. However, there is a paucity of published data on craniospinal setup
reproducibility to guide appropriate planning treatment volume (PTV) margins. We sought to
evaluate the setup accuracy of patients undergoing CSI to optimize PTV margins. Methods
and Materials We measured residual setup deviation between simulation computed
tomography (CT) and daily megavoltage CT after couch shifts made by therapists after …

Purpose/Objective (s): Craniospinal irradiation (CSI) using tomotherapy has advantages
over standard 3D techniques. When treating a large volume in a single plan, set-up
reproducibility is paramount. There is a paucity of published data on craniospinal setup
reproducibility to guide appropriate planning treatment volume (PTV) margins. We sought to
evaluate the setup accuracy of CSI patients to assist in optimal PTV margins.
Materials/Methods: We collected data from 10 patients who completed CSI between May …
