Conclusion In our clinic, the breast protocol with full rotation is used for breast cancer patients as the increase of imaging dose compared to planar imaging was found to be acceptable. The reduced dose using a partial arc could not motivate adaptation of our standards for the isocenter position. For pediatric treatments, CBCT is only used when it is motivated, for example when 6D corrections of the couch is needed or the target is close to an organ at risk. In these cases, the protocol with reduced mAs and the imaging source sweeping below the patient is used as this gives the lowest doses to organs at risk.
