Abstract
A control circuit accesses information regarding a plurality of pre-existing vetted radiation treatment plans for a variety of patients and uses that information to train at least one model (such as a dose volume histogram estimation model). The control circuit then uses that model to develop estimates for a radiation treatment plan for a particular patient. The control circuit can then use those estimates to develop a candidate radiation treatment plan.
Claims18
An apparatus comprising:
- a memory having stored therein information regarding a plurality of pre-existing vetted radiation treatment plans for a variety of patients;
- a control circuit operably coupled to the memory and configured to:
- identify outlier data in the information;
- avoid relying upon at least some of the outlier data while training at least one model;
- develop estimates for a radiation treatment plan for a particular patient as a function, at least in part, of the at least one model.
