Abstract

A graphical user interface is configured for display on a computer display. The graphical user interface includes a dose rate slider configured to enable a user to select a range of radiation dose rates of a radiotherapy plan, and a display image configured to present an image. The dose rate slider may be selectable among less than a value of the dose rate slider, and more than a value of the dose rate slider.

First claim

We claim:

1. A graphical user interface configured for display on a computer display, the graphical user interface comprising: a dose rate slider configured to enable a user to directly select a range of radiation dose rates of a radiotherapy plan; and a display image configured to present an image of radiation dosage of said radiotherapy plan, the display image displaying information of radiation doses corresponding to dose rates that are greater than or equal to a lowest dose rate of said range of radiation dose rates.

2. The graphical user interface of claim 1 , wherein said range is selectable among less than a first value of said dose rate slider, and more than a second value of said dose rate slider.

3. The graphical user interface of claim 1 , wherein the graphical user interface is configured to display said display image in response to a user change of said dose rate slider in less than 1 second.

4. The graphical user interface of claim 3 , wherein the graphical user interface is configured to display said display image responsive to a user change of said dose rate slider in 100 milliseconds (ms) or less.

5. The graphical user interface of claim 1 , wherein said display image comprises a dose volume histogram, and wherein said dose volume histogram displays information of radiation doses delivered at a dose rate corresponding to said range.

6. The graphical user interface of claim 1 , wherein said display image comprises an anatomical plane image, and wherein said anatomical plane image displays information of radiation doses delivered at a dose rate corresponding to said range.

7. The graphical user interface of claim 1 , wherein said display image is configured to display a portion of said radiotherapy plan that corresponds to FLASH radiotherapy.

8. A computer-implemented method for dynamically updating displays of radiotherapy plan information in a graphical user interface (GUI), the computer-implemented method comprising: displaying a first window comprising graphical information of said radiotherapy plan information in a first format within the GUI on a computer display; displaying a second window comprising a dose rate slider configured to display a range of dose rates within the GUI; accepting user input via said dose rate slider to directly select said range of dose rates; and automatically updating said first window to display radiation dosage delivered at greater than or equal to a lowest dose rate of said range of dose rates.

9. The computer-implemented method of claim 8 , wherein said first window comprises an anatomical plane image.

10. The computer-implemented method of claim 9 , wherein said anatomical plane image comprises an axial plane image.

11. The computer-implemented method of claim 8 , wherein said first window comprises a dose volume histogram.

12. The computer-implemented method of claim 8 , wherein said dose rate slider is operable to select a range of dose rates from among less than a first value of said dose rate slider, and more than a second value of said dose rate slider.

13. The computer-implemented method of claim 8 , wherein said updating is performed within a duration of 100 milliseconds (ms) or less.

14. The computer-implemented method of claim 8 , the computer-implemented method further comprising:
precomputing updates to said first window corresponding to a plurality of dose rate ranges.

15. The computer-implemented method of claim 8 wherein, subsequent to said updating, said first window is configured to display a portion of said radiotherapy plan information that corresponds to FLASH radiotherapy.

16. A non-transitory computer-readable storage medium having computer-executable instructions that, when executed by one or more processors, are configured to cause a computer system to perform a method for dynamically updating displays of radiotherapy plan information in a graphical user interface (GUI), the method comprising: displaying a first window comprising graphical information of said radiotherapy plan information in a first format within the GUI on a computer display; displaying a second window comprising a dose rate slider configured to display a range of dose rates within the GUI; accepting user input via said dose rate slider to directly change said range of dose rates; and automatically updating said first window to display radiation dosage delivered at greater than or equal to a lowest dose rate of said range of dose rates.

17. The non-transitory computer-readable storage medium of claim 16 , wherein said first window comprises an axial plane image.

18. The non-transitory computer-readable storage medium of claim 16 , wherein said first window comprises a dose volume histogram.

19. The non-transitory computer-readable storage medium of claim 16 wherein said dose rate slider is operable to select a range of dose rates from among less than a first value of said dose rate slider, and more than a second value of said dose rate slider.

20. The non-transitory computer-readable storage medium of claim 16 , wherein said method further comprises precomputing updates to said first window corresponding to a plurality of dose rate ranges.

21. The graphical user interface of claim 1 , wherein
the dose rate slider includes an indicator that is adjustable along a track,
the track includes radiation dose rates between a minimum dose rate and a maximum dose rate, and
the range of radiation dose rates is set by moving the indicator along the dose rate slider to a position associated with a first dose rate.
