At one of our centers have been using VARIAN RPM in CT SIM to coach the patient into an appropriate breath hold level for DIBH. At another center where we recently installed a new linac and VisionRT, we do not have VARIAN RPM at all. I was just informed that GateCT is not useful for determining breath hold level in CT SIM. How do centers determine appropriate breath hold levels for their DIBH patients in CT SIM? I assume one can use the lateral scout image to coach the patient into an appropriate breath hold or one could use skin marks and a ruler, but is there a better way to go about this in the absence of a VARIAN RPM system in CT SIM?
