Conclusion This first study demonstrates using HA as an efficient strategy for WBRTHA treatments in a TrueBeam HD-MLC linac. As in reference studies, the main advantages found for this modality compared to coplanar VMAT are the gains in the dosimetric OAR sparing, the reduction of the high doses to PTV and the increase of minimum doses to PTV, being less time-consuming (stressed by FFF) and dependent on the user experience. We believe that this increase in efficiency and confidence due to process automation ultimately improves patient care. Therefore, HA has become our new standard technique for WBRTHA
