Abstract

Disclosed herein are radiotherapy methods and systems that can display a workflow-oriented graphical user interface(s). In an embodiment, a method comprises retrieving, by a server, information from a radiotherapy file associated with a patient, the information comprising an alignment data of at least a treatment region of the patient; presenting, by the server, for display on a graphical user interface, an image corresponding to the patient positioned on a couch of a radiotherapy machine, the image comprising an overlay on a surface of the patient in the treatment region; and presenting, by the server, for display, a visually distinct revised overlay for at least a portion of the surface of the patient in the treatment region that matches, within a predetermined margin of error, the alignment data.

Claims (29)

1. A method comprising:

retrieving, by a server, information from a radiotherapy file associated with a patient, the information comprising an alignment data of at least a treatment region of the patient;

presenting, by the server, for display on a graphical user interface, an image corresponding to the patient positioned on a couch of a radiotherapy machine, the image comprising an overlay on a surface of the patient in the treatment region; and

presenting, by the server, for display, a visually distinct revised overlay for at least a portion of the surface of the patient in the treatment region that matches, within a predetermined margin of error, the alignment data, wherein the at least the portion of the surface represents an extent to which the patient is in a satisfactory position for the radiotherapy treatment based on a reference surface included within the radiotherapy file and corresponding to one or more radiotherapy treatment attributes received from a treating physician.

2. The method of claim 1 , wherein the alignment data of at least a treatment region of the patient is in reference to a reference point.

3. The method of claim 1 , wherein the graphical user interface is displayed on a screen on a gantry of the radiotherapy machine.

4. The method of claim 3 , wherein the screen is positioned on a throat of the gantry.

5. The method of claim 1 , further comprising:

presenting, by the server, for display, a graphical indicator corresponding to the alignment data.

6. The method of claim 1 , wherein visually distinct corresponds to a different visual pattern.

7. The method of claim 1 , wherein visually distinct corresponds to a different color.

8. The method of claim 1 , wherein visually distinct corresponds to a different texture.

9. The method of claim 1 , wherein the image is received from a camera positioned on at least one of a gantry of the radiotherapy machine, the couch, or within a room that includes the radiotherapy machine.

10. The method of claim 1 , wherein the server further displays a reference point associated with the patient or instructions to aligning the patient.

11. A system comprising:

a server comprising a processor and a non-transitory computer-readable medium containing instructions that when executed by the processor causes the processor to perform operations comprising:

retrieve information from a radiotherapy file associated with a patient, the information comprising an alignment data of a treatment region of the patient;

present for display on a graphical user interface, an image corresponding to the patient positioned on a couch of a radiotherapy machine, the image comprising an overlay on a surface of the patient in the treatment region; and

present, for display, a visually distinct revised overlay for at least a portion of the surface of the patient in the treatment region that matches, within a predetermined margin of error, the alignment data, wherein the at least the portion of the surface represents an extent to which the patient is in a satisfactory position for the radiotherapy treatment based on a reference surface included within the radiotherapy file and corresponding to one or more radiotherapy treatment attributes received from a treating physician.

12. The system of claim 11 , wherein the alignment data of at least a treatment region of the patient is in reference to a reference point.

13. The system of claim 11 , wherein the graphical user interface is displayed on a screen on a gantry of the radiotherapy machine.

14. The system of claim 13 , wherein the screen is positioned on a throat of the gantry.

15. The system of claim 11 , further comprising:

present for display, a graphical indicator corresponding to the alignment data.

16. The system of claim 11 , wherein visually distinct corresponds to a different visual pattern.

17. The system of claim 11 , wherein visually distinct corresponds to a different color.

18. The system of claim 11 , wherein visually distinct corresponds to a different texture.

19. The system of claim 11 , wherein the image is received from a camera positioned on at least one of a gantry of the radiotherapy machine, the couch, or within a room that includes the radiotherapy machine.

20. The system of claim 11 , server further displays a reference point associated with the patient or instructions to aligning the patient.
