Résumé
This study evaluates enhancements introduced in version 4.0 of Brainlab's Pencil Beam algorithm within the Elements treatment planning system (TPS) for radiotherapy dose calculations. These updates include a new scatter model to improve dose calculation accuracy and updated commissioning recommendations involving asynchronous sweeping gap (a-SG) measurements to refine multileaf collimator (MLC) parameters such as dynamic leaf shift (DLS) and tongue-and-groove (TG) size.
