Abstract

A system for treating an ocular tumor having a cone, a collimator, a light source and a camera is disclosed. The cone includes a cone input and a cone output and is capable of being mounted and un-mounted to a treatment nozzle. The cone input receives radiation from the treatment nozzle for the treatment of the ocular tumor. The collimator is coupled to the cone output and configured to collimate radiation received by the cone output. This collimated radiation is directed to the patient having the ocular tumor. The light source coupled to the cone. The light source is configured to provide a focusing point of the eye of the patient. A camera coupled to the cone monitors the position of the eye of the patient.

Claims

1. A system for treating an ocular tumor, the system comprising:

a removable cone configured to transfer radiation from a treatment nozzle to a patient, the removable cone having a cone input and a cone output, the cone input being configured to receive the radiation from the treatment nozzle and the cone output being configured to output the radiation to the patient;

a collimator connected with the cone output, the collimator configured to collimate the radiation received from the cone output;

a light source connected with the cone and configured to provide a focusing point of an eye of the patient;

a camera connected with the cone and for monitoring a position of an eye of a patient; and

a base plate coupled to the input of the cone, the base plate capable of being mounted and un-mounted to the treatment nozzle.

2. The system of claim 1, further comprising:

a first x-ray source configured to transmit x-rays through the patient; and

a first flat panel detector configured to receive x-rays transmitted by the first x-ray source.

3. The system of claim 2, further comprising:

a second x-ray source configured to transmit x-rays through the patient; and

a second flat panel detector configured to receive x-rays transmitted by the second x-ray source.

4. The system of claim 3, further comprising:

the treatment nozzle having a nozzle input and a nozzle output;

the treatment nozzle output being coupled to the base plate and configured to direct radiation received by the treatment nozzle input to the cone input.

5. The system of claim 1, further comprising a transparent projection plate coupled to the cone, the transparent projection plate being configured to display light generated by the light source.

6. The system of claim 5, wherein the transparent projection plate is made of a transparent polymer.

7. The system of claim 1, wherein the light source is a light emitting diode.

8. The system of claim 1, further comprising an adjustable cone extension located between the cone and the collimator, the cone extension being configured to adjust the distance between the collimator and the patient.

9. The system of claim 8, wherein the cone extension further comprises:

a front portion coupled to the collimator, the front portion substantially facing the patient;

a side portion attached to the first portion, the side portion extending away from the patient.

10. The system of claim 8, further comprising a servo motor mechanically coupled to the cone extension for adjusting the distance between the collimator and the patient.

11. The system of claim 1, further comprising a cable connected to the camera, the cable capable of being disconnected from the camera.

12. The system of claim 1, further comprising a cable connected to the light source, the cable capable of being disconnected from the light source.

13. The system of claim 2, further comprising:

the treatment nozzle having a nozzle input and a nozzle output;

the treatment nozzle output being coupled to the base plate and configured to direct radiation received by the treatment nozzle input to the cone input.

14. The system of claim 2, further comprising a transparent projection plate coupled to the cone, the transparent projection plate being configured to display light generated by the light source.

15. The system of claim 14, wherein the transparent projection plate is made of a transparent polymer.

16. The system of claim 2, wherein the light source is a light emitting diode.

17. The system of claim 2, further comprising an adjustable cone extension located between the cone and the collimator, the cone extension being configured to adjust the distance between the collimator and the patient.

18. The system of claim 17, wherein the cone extension further comprises:

a front portion coupled to the collimator, the front portion substantially facing the patient;

a side portion attached to the first portion, the side portion extending away from the patient.

19. The system of claim 17, further comprising a servo motor mechanically coupled to the cone extension for adjusting the distance between the collimator and the patient.

20. The system of claim 2, further comprising a cable connected to the camera, the cable capable of being disconnected from the camera.

21. The system of claim 1, further comprising a cable connected to the light source, the cable capable of being disconnected from the light source.

22. A method for treating an ocular tumor, the method comprising:

attaching a removable cone to a treatment nozzle, the cone having a cone input and a cone output;

locating a patient between the cone and at least one x ray source;

providing a radiation to the treatment nozzle,

transferring the radiation from the treatment nozzle to the patient via the removable cone, wherein radiation emitted by treatment nozzle is inputted into the cone input and is then outputted to the patient from the cone output;

providing x-rays from the at least one x-ray source to the patient.

23. The method of claim 22, wherein the steps of providing a radiation to the treatment nozzle and providing x-rays from the at least one x-ray source to the patient occur simultaneously.

24. The method of claim 22, wherein the steps of providing a radiation to the treatment nozzle and providing x-rays from the at least one x-ray source to the patient occur sequentially.
