For anyone using aquaplast as bolus for DIBH’s. We’re looking into it as an option and have a few questions. What size are you using? What are you using to heat it? What thickness and is it every day every other? Do you find that the final thickness of the aquaplast is consistent after conforming it to the patient , or does the thickness very without? Are you still just doing 2 scans in sim: 1 FB and 1 BH with the aquaplast already on? For cases where the supraclav is also being treated, do you remove the aquaplast when treating that area? And if so does it change the patient’s surface in a way that might affect the way AlignRT picks it up since the plan was made off of the scan with aquaplast on? Any information is greatly appreciated as this has been an issue with us for quite some time.
