Figure 4From: Predicted risks of radiogenic cardiac toxicity in two pediatric patients undergoing photon or proton radiotherapyDifferential DVHs of the whole heart and heart substructures. DVHs from (a) proton and (b) photon treatment plans for the MB patient and the HD patient. For the photon plan, the DVHs were taken from TPS directly; for the proton plan, the DVHs for primary dose were obtained from TPS, then a mean neutron equivalent dose was added uniformly to the primary DVHs.Back to article page
