What is Localized Extra Focal Dose Collimator Angle Dependence D 2020 Radiation Phys about?

This study investigates the localized extra-focal dose (LEFD) during Volumetric Modulated Arc Therapy (VMAT) using Monte Carlo simulations with PRIMO software. It finds that LEFD can be significant, reaching up to 160% of the mean transmitted dose, and suggests that optimizing the collimator rotation angle can help minimize this out-of-field dose without compromising treatment objectives. The results indicate that adjusting the collimator angle effectively relocates LEFD away from the patient
