An example of how OAR sub-DVHs contribute to the ORBIT-RT model for the k = 3 shell of a bladder. All sub-DVHs (light blue) from training plans are mapped to the same normalized dose axis. The ORBIT-RT model (dark blue) is the pointwise arithmetic mean of these sub-DVHs. This model kernel is functionally equivalent to the probability density of having a given dose in shell k of OAR j. DVH, dose-volume histogram; OAR, organs-at-risk; ORBIT-RT, Online Real-time Benchmarking Informatics Technology for RadioTherapy.
