Doses to the heart and lungs: Absolute volumes for doses (V5 = Volume that receives 5Gy etc) and relative volumes (%) are given for patient A and patient B. Relevant measurable values of doses to OAR are nearly halfened by DIBH vs. FB in patient A. In patient B there is a visible reduction of lower lung doses (V5) that might be relevant in terms of RP protection.
