Hi, in my clinic, we are preparing to use Elekta Response (Auto Beam Hold) with AlignRT on SBRT patients (Lung and Liver). Is there anyone out there who has experience doing gating treatment or breath hold treatment using the similar system? One of my concern is that often, during VMAT delivery, there are specific gantry angles where AlignRT loses it’s signal (not so much of an issue for a fixed beam treatment like breast). Usually, if manual beam on/off is used, therapist won’t stop the beam moving through that specific sector. However with Auto Beam Hold, I’m afraid that the beam would always get stuck in that sector making smooth delivery difficult. Any feedback would be greatly appreciated.
