Abstract

In various embodiments, a radiation therapy method can include loading a planning image of a target in a human. In addition, the position of the target can be monitored. A computation can be made of an occurrence of substantial alignment between the position of the target and the target of the planning image. Furthermore, after the computing, a beam of radiation is triggered to deliver a dosage to the target in a short period of time (e.g., less than a second).

First claim

What is claimed is:

1. A radiation therapy method comprising:
loading a planning image of a target in a human;
monitoring the position of the target;
computing an occurrence of substantial alignment between the position of the target and the target of the planning image; and
after the computing, triggering a beam of radiation to deliver at least 4 grays within a second to the target.

2. The method of claim 1 , wherein the monitoring comprises a real-time video feed.

3. The method of claim 1 , wherein the monitoring comprises real-time fluoroscopic imaging.

4. The method of claim 1 , wherein the monitoring comprises magnetic resonance imaging.

5. The method of claim 1 , wherein the monitoring comprises cone beam computed tomography.

6. The method of claim 1 , wherein the monitoring comprises digital tomosynthesis.

7. The method of claim 1 , wherein the monitoring comprises ultrasound.

8. The method of claim 1 , wherein the monitoring comprises fiducial markers.

9. A radiation therapy method comprising:
loading a planning image of a target in a human;
monitoring the position of the target;
computing an occurrence of substantial alignment between the position of the target and the target of the planning image; and
after the computing, triggering a beam of radiation to deliver at least 20 grays within a second to the target.

10. The method of claim 9 , wherein the computing is performed manually by a human.

11. The method of claim 9 , wherein the computing is performed automatically by a computing system.

12. The method of claim 9 , wherein the beam of radiation comprises protons.

13. The method of claim 9 , wherein the beam of radiation comprises photons.

14. The method of claim 9 , wherein the beam of radiation comprises ions.

15. The method of claim 9 , wherein the beam of radiation comprises electrons.

16. A radiation therapy method comprising:
loading a planning image of a target in a human;
monitoring the position of the target;
computing an occurrence of substantial alignment between the position of the target and the target of the planning image; and
after the computing, triggering a beam of radiation to deliver at least 40 grays within a second to the target.

17. The method of claim 16 , wherein the planning image comprises a magnetic resonance imaging (MRI) image.

18. The method of claim 16 , wherein the planning image comprises a computed tomography (CT) image.

19. The method of claim 16 , wherein the computing comprises utilizing a visual representation.

20. The method of claim 16 , wherein the monitoring comprises a four dimensional (4D) cone beam.
