Abstract

The invention comprises a method for treating a tumor of a patient with positively charged particles in a treatment room, comprising the steps of: (1) controlling a cancer therapy treatment system with a main controller, the main controller comprising hardware and software; (2) generating at least one image of the tumor using at least one imaging system controlled by the main controller; (3) using the at least one image and a software coded set of radiation treatment directives, the main controller auto-generating a radiation treatment plan; and (4) the main controller auto-delivering the positively charged particles, via a beam transport system and a nozzle system, from a synchrotron to the tumor according to the radiation treatment plan.

First claim

The invention claimed is:

1. A method for treating a tumor of a patient with positively charged particles in a treatment room, comprising the steps of:
controlling a cancer therapy treatment system with a main controller, said main controller comprising hardware and software;
generating at least one image of the tumor using at least one imaging system controlled by said main controller;
using said at least one image and a software coded set of radiation treatment directives, said main controller auto-generating a radiation treatment plan; and
said main controller auto-delivering the positively charged particles, via a beam transport system and a nozzle system, from a synchrotron to the tumor according to the radiation treatment plan.

2. The method of claim 1 , said step of auto-generating a radiation treatment plan further comprising the steps of:
using a first image of the tumor, generated using the positively charged particles and a scintillation detector, generated in said step of generating at least one image; and
using a second image of the tumor, generated using an X-ray source and X-ray detector, generated in said step of generating at least one image.

3. The method of claim 2 , further comprising the step of:
the patient remaining in contact with a patient positioning system during all of said steps of: (1) generating at least one image of the tumor; (2) auto-generating the radiation treatment plan; and (3) said main controller auto-delivering the positively charged particles from said synchrotron to the tumor.

4. The method of claim 2 , further comprising the step of:
a medical doctor overseeing, without intervening, at least one of: (1) said step of auto-generating the radiation treatment plan and (2) said step of auto-delivering the positively charged particles.

5. The method of claim 2 , further comprising the steps of:
concurrently with said step of auto-delivering the positively charged particles, updating a current shape of the tumor using said at least one imaging system;
said main controller automatically generating an updated radiation treatment plan using the current shape of the tumor; and
continuing said step of auto-delivering the positively charged particles to the tumor using the updated radiation treatment plan.

6. The method of claim 5 , said step of said main controller automatically generating an updated radiation plan implemented in an automated fashion by said hardware and said software of said main controller without a medical doctor altering an input to said software.

7. The method of claim 5 , said step of said main controller automatically generating an updated radiation plan performed without modification of said software.

8. The method of claim 7 , further comprising the step of:
the patient remaining in contact with a patient positioning system during said step of said main controller automatically generating the updated radiation treatment plan.

9. The method of claim 1 , further comprising the step of:
once initiated by an operator of the cancer therapy system, said main controller automating implementation of said step of generating at least one image of the tumor and said step of auto-generating the radiation treatment plan using the at least one image.

10. The method of claim 9 , said step of said main controller automating implementation occurring without a human altering any of said hardware and said software.

11. The method of claim 10 , further comprising the step of:
a medical doctor slowing said cancer treatment system by at least ten percent to allow time for the medical doctor to observe said step of said main controller automating implementation.

12. The method of claim 10 , further comprising the step of:
to initiate a step of auto-generating of an updated radiation treatment plan, said main controller using output of at least one of:
a first fiducial element affixed to a mechanical element co-movable with said nozzle system; and
a fiducial detector receiving a wireless signal from a fiducial marker co-movable with said nozzle system.

13. The method of claim 12 , further comprising the step of:
the updated radiation treatment plan bypassing an intervening object determined to interfere with upcoming and originally planned radiation treatment path in the next minute.

14. An apparatus for treating a tumor of a patient with positively charged particles in a treatment room, comprising:
a cancer therapy treatment system comprising a main controller, said main controller comprising hardware and software, said main controller configured to control said cancer therapy treatment system;
at least one imaging system controlled by said main controller configured to generate at least one image of the tumor;
a software coded set of radiation treatment directives, said main controller configured to auto-generate a radiation treatment plan using said set of radiation treatment directives and the at least one image;
a synchrotron;
a nozzle system; and
a beam transport system, said main controller configured to direct auto-delivery of the positively charged particles from said synchrotron, via said beam transport system, and through said nozzle system to the tumor according to the radiation treatment plan.

15. The apparatus of claim 14 , said at least one imaging system further comprising:
a computed tomography system comprising a scintillation detector, said computed tomography system detecting individual particles of the positively charged particles after passing through the patient.

16. The apparatus of claim 15 , further comprising:
a patient positioning system, said patient positioning system utilized to maintain the patient in an immobilized position during a process of said main controller auto-generating the radiation treatment plan.
