Abstract

A control circuit accesses historical information regarding previously optimized radiation treatment plans for different patients and processes that information to determine the relative importance of different clinical goals. The circuit then facilitates development of a particular plan for a particular patient as a function of the relative importance of the clinical goals. By one approach the control circuit can be configured as a radiation treatment plan recommendation resource that accesses a database of radiation treatment plan formulation content items including at least one of a radiation treatment plan template, an auto-planning algorithm, and an auto-segmentation algorithm. By one approach the control circuit can be configured to, when presenting automatically-generated radiation treatment plans to a user, also co-present an opportunity for the user to signal to a remote entity that none of the plans are acceptable and that the user will instead employ a user-generated plan for the particular patient.

First claim

What is claimed is:

1. A method comprising:
by a control circuit:
accessing historical information regarding a plurality of previously optimized radiation treatment plans corresponding to a plurality of different patients;
processing the historical information to determine a relative importance of a plurality of clinical goals; and
facilitating a development of a particular radiation treatment plan for a particular patient as a function, at least in part, of the relative importance of the plurality of clinical goals.

2. The method of claim 1 , wherein the historical information includes, at least in part, contemporaneous user-identified clinical goals and corresponding radiation dose information for at least some of the plurality of previously optimized radiation treatment plans.

3. The method of claim 1 , wherein processing the historical information to determine a relative importance of a plurality of clinical goals includes automatically prioritizing the plurality of clinical goals with respect to the relative importance.

4. The method of claim 3 , wherein automatically prioritizing the plurality of clinical goals with respect to the relative importance includes prioritizing the plurality of clinical goals as a function of:
contemporaneous user-identified clinical goals;
an acceptance of given ones of the plurality of previously optimized radiation treatment plans for a usage in providing a radiation treatment to a corresponding patient; and
a frequency of usage of particular clinical goals within the historical information.

5. The method of claim 3 , wherein automatically prioritizing the plurality of clinical goals with respect to the relative importance includes prioritizing frequently-used clinical goals higher than less-frequently used clinical goals.

6. The method of claim 1 , wherein the control circuit is further configured as a radiation treatment plan recommendation resource, and wherein the method further comprises, by the control circuit, accessing a database of radiation treatment plan formulation content items including at least one of a radiation treatment plan template, an auto-planning algorithm, and an auto-segmentation algorithm, and recommending at least a particular one of the radiation treatment plan formulation content items to a user seeking to prepare a radiation treatment plan for a particular patient.

7. The method of claim 6 , wherein recommending at least a particular one of the radiation treatment plan formulation content items comprises recommending the at least a particular one of the radiation treatment plan formulation content items as a function of at least one of:
a user-based behavior; and
a non-user-based behavior.

8. The method of claim 1 , wherein the control circuit is further configured to, when presenting a plurality of automatically-generated radiation treatment plans to a user as candidate radiation treatment plans for a particular patient, also co-present an opportunity for the user to signal to a remote entity both that none of the plurality of automatically-generated radiation treatment plans are acceptable and that the user will instead employ a user-generated radiation treatment plan for the particular patient.

9. The method of claim 8 , wherein the opportunity comprises a single user-assertable button.

10. The method of claim 8 , wherein the opportunity further includes an opportunity by which the user submits information regarding specifics of the user-generated radiation treatment plan to the remote entity.

11. An apparatus comprising:
a control circuit configured to:
access historical information regarding a plurality of previously optimized radiation treatment plans corresponding to a plurality of different patients;
process the historical information to determine a relative importance of a plurality of clinical goals; and
facilitate a development of a particular radiation treatment plan for a particular patient as a function, at least in part, of the relative importance of the plurality of clinical goals.

12. The apparatus of claim 11 , wherein the historical information includes, at least in part, contemporaneous user-identified clinical goals and corresponding radiation dose information for at least some of the plurality of previously optimized radiation treatment plans.

13. The apparatus of claim 11 , wherein the control circuit is configured to process the historical information to determine a relative importance of a plurality of clinical goals by, at least in part, automatically prioritizing the plurality of clinical goals with respect to the relative importance.

14. The apparatus of claim 13 , wherein the control circuit is configured to automatically prioritize the plurality of clinical goals with respect to the relative importance by, at least in part, prioritizing the plurality of clinical goals as a function of:
contemporaneous user-identified clinical goals;
an acceptance of given ones of the plurality of previously optimized radiation treatment plans for a usage in providing a radiation treatment to a corresponding patient; and
a frequency of usage of particular clinical goals within the historical information.

15. The apparatus of claim 13 , wherein the control circuit is configured to automatically prioritize the plurality of clinical goals with respect to the relative importance by, at least in part, prioritizing frequently-used clinical goals higher than less-frequently used clinical goals.

16. The apparatus of claim 11 , wherein the control circuit is further configured as a radiation treatment plan recommendation resource that accesses a database of radiation treatment plan formulation content items including at least one of a radiation treatment plan template, an auto-planning algorithm, and an auto-segmentation algorithm, and recommends at least a particular one of the radiation treatment plan formulation content items to a user seeking to prepare a radiation treatment plan for a particular patient.

17. The apparatus of claim 16 , wherein the control circuit is further configured to recommend at least a particular one of the radiation treatment plan formulation content items by recommending the at least a particular one of the radiation treatment plan formulation content items as a function of at least one of:
a user-based behavior; and
a non-user-based behavior.

18. The apparatus of claim 11 , wherein the control circuit is further configured to, when presenting a plurality of automatically-generated radiation treatment plans to a user as candidate radiation treatment plans for a particular patient, also co-present an opportunity for the user to signal to a remote entity both that none of the plurality of automatically-generated radiation treatment plans are acceptable and that the user will instead employ a user-generated radiation treatment plan for the particular patient.

19. The apparatus of claim 18 , wherein the opportunity comprises a single user-assertable button.

20. The apparatus of claim 18 , wherein the opportunity further includes an opportunity by which the user submits information regarding specifics of the user-generated radiation treatment plan to the remote entity.
