Fig. 2 DVHs for all target volumes for case 1 (top two DVHs) and case 2 (bottom two DVHs). To the left DVHs in relative volume and absolute dose and to the right absolute volume and dose. All targets with own treatment plan, yellow dashed line to the right represents the size of the consensus volume.
