I’d like to know how many people are treating DIBH with bolus, if they are 2 field, 3, or 4, and how things are going. What type of bolus are you using? Do you find it conforms well? How much time do you give to treat these patients? We are finding it very difficult to treat DIBHs using VisionRT. Our biggest issue seems to be that once we’ve set up and started treating, the patient comes out of tolerance and we have to go back in several times to remove the bolus and and take a new reference capture. Right now our tolerances are set at .3cm. Do most people open their tolerances? Any info you can provide is extremely appreciated!
