Hi JOse´╝îIn our center, we have 2 CT scanners and only one RPM System. We don’t start DIBH either. The main reason is we can’t assurance the breath level by using Varian RPM System, cause if you use laser and base on the pen marks on the patient’s hand side, you can’t sure that every deep breath is in one same level, but if you have the real-time video camera to verify the every laser line and see is there two sign are matched, however, we also can’t quite confirm immediately is RPM shows the breath curves are correct, cus it only shows a part of our breath process, the lowest point on the breath curves in RPM system is not the actual deep breath reference. So you can prepare for DIBH make sure you have the real-time camera in CT room.
