SU-E-T-600: Utilizing Collimator Rotation to Increase Maximum Treatable Target Dimensions Using an Elekta Synergy-S with Beam Modulator Multileaf Collimator

Abstract

Changing the collimator angle of the BMx Elekta-S machine allows for a 3cm length increase of targets up to 5cm. Further work will assess clinical suitability of these findings for treatment of head and neck tumors and spinal masses.
