Abstract

A method of presenting a progress of a treatment planning includes determining dose information based on a treatment model, determining objective information that is associated with the treatment model, using the dose information and the objective information to determine a three-dimensional graphic that indicates with how well an objective of the treatment planning is met, wherein the three-dimensional graphic is determined using a processor, and displaying the three-dimensional graphic in a screen.

Claims (46)

1. A method of presenting a progress of a treatment planning, comprising:

determining simulated dose information based on a treatment model;

determining objective information representing one or more objective(s) to be achieved, the objective information associated with the treatment model, wherein the objective information comprises a desired target dose, a maximum dose for critical organ, a prescribed minimum average dose at target tissue, a prescribed maximum average dose at healthy tissue, or a combination of two or more of the foregoing;

using the simulated dose information and the objective information to determine a three-dimensional graphic that indicates a result of a comparison between the simulated dose information and the objective information, wherein the three-dimensional graphic is determined using a processor; and

displaying the three-dimensional graphic in a screen.

2. The method of claim 1 , wherein the three-dimensional graphic is displayed in the screen before the treatment planning is completed.

3. The method of claim 1 , wherein the three-dimensional graphic is displayed in the screen during a treatment session in which a treatment machine is in idling mode.

4. The method of claim 1 , wherein the three-dimensional graphic represents dose that is needed to achieve a target level.

5. The method of claim 1 , wherein the three-dimensional graphic indicates gradient dose information from a target dose.

6. The method of claim 1 , wherein the three-dimensional graphic indicates spatial objective function information calculated from dose values.

7. The method of claim 1 , wherein the three-dimensional graphic indicates gradient of spatial objective function information calculated from dose values.

8. The method of claim 1 , wherein the three-dimensional graphic includes a partial covering of a volume formed using one or more filters.

9. The method of claim 1 , wherein the three-dimensional graphic includes a partial volume formed using one or more filters.

10. The method of claim 1 , further comprising superimposing the three-dimensional graphic with an image of a tissue structure.

11. The method of claim 1 , wherein the three-dimensional graphic comprises a color map, and wherein different colors in the map represent different respective degrees in which an objective of the treatment planning is met.

12. A system for presenting a progress of a treatment planning, comprising:

a processor configured for:

determining simulated dose information based on a treatment model;

determining objective information representing one or more objective(s) to be achieved, the objective information associated with the treatment model, wherein the objective information comprises a desired target dose, a maximum dose for critical organ, a prescribed minimum average dose at target tissue, a prescribed maximum average dose at healthy tissue, or a combination of two or more of the foregoing;

using the simulated dose information and the objective information to determine a three-dimensional graphic that indicates a result of a comparison between the simulated dose information and the objective information; and

outputting the three-dimensional graphic for display in a screen.

13. The system of claim 12 , wherein the processor is configured to output the three-dimensional graphic for display in the screen before the treatment planning is completed.

14. The system of claim 12 , wherein the processor is configured to output the three-dimensional graphic for display in the screen during a treatment session in which a treatment machine is in idling mode.

15. The system of claim 12 , wherein the three-dimensional graphic represents dose that is needed to achieve a target level.

16. The system of claim 12 , wherein the three-dimensional graphic indicates gradient dose information from a target dose.

17. The system of claim 12 , wherein the three-dimensional graphic indicates spatial objective function information calculated from dose values.

18. The system of claim 12 , wherein the three-dimensional graphic indicates gradient of spatial objective function information calculated from dose values.

19. The system of claim 12 , wherein the three-dimensional graphic includes a partial covering of a volume formed using one or more filters.

20. The system of claim 12 , wherein the three-dimensional graphic includes a partial volume formed using one or more filters.

21. The system of claim 12 , wherein the processor is further configured to superimpose the three-dimensional graphic with an image of a tissue structure.

22. The system of claim 12 , wherein the three-dimensional graphic comprises a color map, and wherein different colors in the map represent different respective degrees in which an objective of the treatment planning is met.

23. A computer program product having a non-transitory medium storing a set of instructions, an execution of which causes a method of presenting a progress of a treatment planning to be performed, the method comprising:

determining simulated dose information based on a treatment model;

determining objective information representing one or more objective(s) to be achieved, the objective information associated with the treatment model, wherein the objective information comprises a desired target dose, a maximum dose for critical organ, a prescribed minimum average dose at target tissue, a prescribed maximum average dose at healthy tissue, or a combination of two or more of the foregoing;

using the simulated dose information and the objective information to determine a three-dimensional graphic that indicates a result of a comparison between the simulated dose information and the objective information; and

displaying the three-dimensional graphic in a screen.

24. The computer program product of claim 23 , wherein the three-dimensional graphic is displayed in the screen before the treatment planning is completed.

25. The computer program product of claim 23 , wherein the three-dimensional graphic is displayed in the screen during a treatment session in which a treatment machine is in idling mode.

26. The computer program product of claim 23 , wherein the three-dimensional graphic represents dose that is needed to achieve a target level.

27. The computer program product of claim 23 , wherein the three-dimensional graphic indicates gradient dose information from a target dose.

28. The computer program product of claim 23 , wherein the three-dimensional graphic indicates spatial objective function information calculated from dose values.

29. The computer program product of claim 23 , wherein the three-dimensional graphic indicates gradient of spatial objective function information calculated from dose values.

30. The computer program product of claim 23 , wherein the three-dimensional graphic includes a partial covering of a volume formed using one or more filters.

31. The computer program product of claim 23 , wherein the three-dimensional graphic includes a partial volume formed using one or more filters.

32. The computer program product of claim 23 , wherein the method further comprises superimposing the three-dimensional graphic with an image of a tissue structure.

33. The computer program product of claim 23 , wherein the three-dimensional graphic comprises a color map, and wherein different colors in the map represent different respective degrees in which an objective of the treatment planning is met.
