Abstract

A patient treatment system includes one or more automated patient transporters configured to move a patient from a preparation area to one of a plurality of alternative treatment areas, and to position the patient relative to a therapeutic radiation beam. Both transportation of the patient and positioning of the patient are optionally performed while the patient is secured to one of the patient transporters. A control system may be used to both position and transport the patient responsive to a patient treatment plan.

First claim

What is claimed is:

1. A treatment system comprising:
a particle beam source configured to generate a therapeutic beam of particles;
a particle beam nozzle to direct the therapeutic beam of particles in a first treatment area; and
an automated patient transport configured to transport a patient on a patient support from a preparation area to the first treatment area and to position a treatment volume within the patient relative to the therapeutic beam of particles, and configured to support the patient in receiving the therapeutic beam of particles, the automated patient transport including a position sensor providing signals for determining positions of the sensor and configured for use in determining the relative positions of the treatment volume and the therapeutic beam of particles,
wherein the preparation area is protected from radiation generated within the first treatment area by one or more barriers including shielding, and the patient support is integrally connected to the patient transport and inseparable from the patient transport in transporting the patient, positioning a treatment volume within the patient, and supporting the patient in receiving the therapeutic beam of particles.

2. The treatment system of claim 1 further comprising a control system configured to direct the patient transport to move.

3. The treatment system of claim 2 wherein the control system is configured to direct the patient transport to move based on at least signals received from the position sensor in the patient transport.

4. The treatment system of claim 1 , wherein the position sensor is configured to position the treatment volume relative to the therapeutic beam of particles to within +/−2.0 millimeters.

5. The treatment system of claim 1 , wherein the first treatment area is one of a plurality of treatment areas and the patient transport is configured to transport the patient to any one of the plurality of treatment areas responsive to a control system.

6. The treatment system of claim 1 , wherein the first treatment area is one of a plurality of treatment areas and the patient transport is configured to transport the patient to any one of the plurality of treatment areas responsive to a treatment plan.

7. The treatment system of claim 1 , wherein the automated patient transport is further configured to alternatively position the treatment volume relative to a plurality of therapeutic beams of particles within the first treatment area.

8. The treatment system of claim 1 , wherein the automated patient transport is further configured to transport the patient from the first treatment area back to the preparation area.

9. A method comprising:
generating position information by detecting a position of a treatment volume of a patient relative to a position sensor of an automated patient transporter including a patient support supporting the patient;
transporting the patient from a preparation area to a treatment area using the automated patient transporter, the preparation area being protected from radiation generated at the treatment area by one or more barriers including shielding;
determining a position of the automated patient transporter within the treatment area using the position sensor;
positioning the treatment volume relative to a treatment beam disposed within the treatment area, using the automated patient transporter, a position of the treatment volume relative to the treatment beam being determined using the position information; and
delivering a therapeutic beam to the treatment volume in the patent, the patient being supported by the automated patient transporter during the delivery of the therapeutic beam, wherein the patient support is integrally connected to the patient transporter and inseparable from the patient transporter in transporting the patient, positioning a treatment volume within the patient, and supporting the patient in delivering the therapeutic beam.

10. The method of claim 9 , wherein the automated patient transport is configured to alternatively receive members of a plurality of patient supports including a patient support configured to support the patient in a sitting position and a patient support configured to support the patient in a supine position.

11. The method of claim 10 , further including selecting the treatment area from among a plurality of alternative treatment areas.

12. The method of claim 10 , further including programming the automated patient transporter to transport the patient to the treatment area.

13. The method of claim 10 , further including programming a transport path for use by the automated patient transporter to guide the patient transporter to the treatment area.

14. The method of claim 9 , further including identifying the patient.

15. The method of claim 14 , further including using an identity of the patient to access a treatment plan.

16. The method of claim 14 , wherein the treatment plan includes characteristics of the treatment volume.

17. The method of claim 14 , further including using the treatment plan to control the treatment beam.

18. The method of claim 14 , further including using the treatment plan to select the treatment area from a plurality of alternative treatment areas.

19. The method of claim 9 wherein the automated patient transporter transporting the patient is directed by a control system.

20. The method of claim 19 wherein the control system directs the patient transporter based on at least signals received from the position sensor in the patient transport.

21. The method of claim 9 , wherein the automated patient transport is configured for transporting the patient in alternatively a supine or sitting position.

22. A treatment system comprising:
a radiation source configured to generate a therapeutic beam of radiation;
a treatment head to direct the therapeutic beam of radiation in a first treatment area; and
an automated patient transport configured to transport a patient on a patient support from a preparation area to the first treatment area and to position a treatment volume within the patient relative to the therapeutic beam of radiation, and configured to support the patient in receiving the therapeutic beam of radiation, the automated patient transport including a position sensor providing signals for determining positions of the sensor and configured for use in determining the relative positions of the treatment volume and the therapeutic beam of radiation,
wherein the preparation area is protected from radiation generated within the first treatment area by one or more barriers including shielding, and the patient support is integrally connected to the patient transport and inseparable from the patient transport in transporting the patient, positioning a treatment volume within the patient, and supporting the patient in receiving the therapeutic beam of radiation.

23. The treatment system of claim 22 further comprising a control system configured to direct the patient transport to move.

24. The treatment system of claim 23 wherein the control system is configured to direct the patient transport to move based on at least signals received from the position sensor in the patient transport.

25. The treatment system of claim 22 , wherein the position sensor is configured to position the treatment volume relative to the therapeutic beam of radiation to within +/−2.0 millimeters.

26. The treatment system
