Abstract

A method and apparatus for treatment planning are described.

Claims (29)

1. A method of displaying information in a treatment planning system, comprising:

separating, by a processing device, a pre-delivery radiation treatment plan into a plurality of treatment planning tasks to be performed by the treatment planning system, wherein the plurality of treatment tasks comprise two or more of:

loading, via a load task, patient data comprising a plurality of medical images;

visualizing, via a visualize task, the plurality of medical images of the patient; and

contouring, via a contour task, a first anatomical volume of interest of the patient, on one of the plurality of images, corresponding to a treatment target to receive radiation, wherein the contour task further to contour a second anatomical volume of interest of the patient, on one of the plurality of images, corresponding to a critical structure to avoid radiation;

optimizing, via a plan task, a dose distribution based on a minimum dose constraint and a maximum dose constraint using at least one of an iterative algorithm or a non-iterative algorithm, wherein:

the iterative algorithm to optimize deviations above the maximum dose constraint and below the minimum dose constraint by generating a set of radiation treatment beams to an initial dose distribution calculation, and subsequently attempt to improve the initial dose distribution calculation by altering the one or more radiation treatment beams; and

the non-iterative algorithm to minimize a number of monitor units subject to the minimum dose constraint and the maximum dose constraint;

displaying, by the processing device, the two or more of the plurality of treatment planning tasks in separate user interfaces that are not simultaneously viewable by a user of the treatment planning system to receive inputs, wherein the displaying further comprises displaying the contour of the first anatomical volume of interest and the second anatomical volume of interest where the two or more of the plurality of treatment tasks comprises the contour task; and

generating, by the processing device, the pre-delivery radiation treatment plan using the inputs received in the separate user interfaces.

2. The method of claim 1 , wherein information corresponding to one of the plurality of tasks in not displayed in a user interface that corresponds to a different task than the one of the plurality of tasks.

3. The method of claim 1 , wherein information and data entry corresponding to a particular task of the plurality of task is only displayed to the user in the user interface corresponding to the particular task.

4. The method of claim 1 , wherein the user is presented with the user interfaces corresponding to the plurality of tasks in a predetermined order.

5. The method of claim 4 , wherein the user is prevented from viewing a user interface of a proceeding task before completing a preceding task of the plurality of tasks.

6. The method of claim 1 , wherein at least one of the plurality of tasks has a plurality of steps and wherein the method further comprises:

displaying two or more of the plurality of steps in separate user interfaces that are not simultaneously viewable by a user.

7. The method of claim 6 , wherein function, information and data entry corresponding to a particular step of the plurality of steps is only displayed to the user in the user interface corresponding to the particular step.

8. The method of claim 1 , wherein the plurality of tasks further comprises an align task.

9. The method of claim 1 , where in the load task is displayed to the user prior to the visualize task.

10. The method of claim 1 , where in the contour task is displayed to the user prior to the plan task.

11. The method of claim 1 , wherein the plurality of tasks are separately displayed to the user in the following order of the load task, the visualize task, the align task, the contour task and the plan task.

12. The method of claim 1 , wherein one of the plurality of tasks is an align tasks with a corresponding user interface for setting a plurality of treatment parameters.

13. The method of claim 12 , wherein the user interface for setting the plurality of treatment parameters prevents the user from setting a proceeding treatment parameter before setting a preceding parameter of the plurality of treatment parameters.

14. The method of claim 13 , wherein the plurality of treatment parameters comprises a treatment anatomy.

15. The method of claim 13 , wherein the plurality of treatment parameters comprises at least one of a number of stages, a treatment path set, a tracking method, a treatment mode, and a beam on time.

16. The method of claim 12 , further comprising forcing the user to set a particular enabled treatment parameter before providing the user the ability to set a different one of the plurality of treatment parameters.

17. The method of claim 12 , wherein the plurality of treatment parameters comprises, in order, at least one of a treatment anatomy, a number of stages, a treatment path set, a tracking method, a treatment mode, and a beam on time, and wherein the user is forced to set each of the plurality of treatment parameters in the order listed.

18. The method of claim 1 , further comprising displaying a targeting slider control to enable the user to define a first number of beams aimed at points internal to a target region and a second number of beams aimed at a boundary of the target region.

19. The method of claim 1 , wherein the visualize task comprises a fuse task to fuse images from multiple imaging modalities.
