Abstract

A proton cyclotron is provided for dedicated use in head, neck and eye cancers, tumors or other medical conditions including pediatric and other cancers or medical conditions. The method of using a proton cyclotron for treating a tumor, cancer or medical condition of a patient includes positioning the patient on a support platform, such as on a patient table or in a robotic chair, and irradiating the tumor, cancer or other medical condition using a proton particle beam from the cyclotron for a predetermined time sufficient to treat the tumor, cancer or medical condition, wherein the proton particle beam produced by the cyclotron has an energy in a range of 70 MeV to 150 MeV and has a beam current in an amount suitable for radiation therapy, as can include a variable range of beam current for the radiation therapy.

Claims (32)

1 . A method of using a cyclotron for treating a tumor, a cancer or a medical condition of a plurality of patients residing in different treatment rooms, comprising the steps of:

positioning each patient of the plurality of patients residing in different treatment rooms on a respective support platform;

placing a particle beam splitter to split a proton particle beam from the cyclotron into multiple beams to provide a plurality of proton particle beams for treating the plurality of patients residing in different treatment rooms; and

providing an irradiation dose to the tumor, the cancer or the medical condition of the plurality of patients using for each patient of the plurality of patients a proton particle beam of the plurality of proton particle beams from the particle beam splitter for a predetermined time to treat the tumor, the cancer or the medical condition,

wherein the proton particle beam produced by the cyclotron has an energy in a range of from 70 MeV to 150 MeV.

2 . The method according to claim 1 , further comprising the step of: generating a tomographic image of the tumor, the cancer or the medical condition from an imaging apparatus positioned near the patient prior to irradiating the tumor, the cancer or the medical condition.

3 . The method according to claim 1 , further comprising the step of: adjusting the irradiation dose by controlling a power and a beam intensity output of the cyclotron.

4 . The method according to claim 1 , wherein the tumor, the cancer or the medical condition is localized in the eye, neck or head of the patient.

5 . The method according to claim 1 , wherein the support platform is positioned on a floor mounted support that is rotatable relative to a longitudinal axis (X-axis) of a delivered one of said plurality of proton particle beams from the particle beam splitter.

6 . The method according to claim 1 , wherein the support platform is positioned on a floor mounted support that is rotatable or moveable up and down relative to a vertical axis (Z-axis) of a delivered one of said plurality of proton particle beams from the particle beam splitter.

14 . The apparatus according to claim 13 , further comprising:

a support platform configured for respectively receiving a patient of the plurality of patients, the support platform being configured to selectively convert from a robotic chair to a patient table and back to the robotic chair.

15 . The apparatus according to claim 13 , further comprising:

a support platform configured for respectively receiving a patient of the plurality of patients, the support platform configured to be positioned on a floor mounted support that is rotatable or moveable relative to a vertical axis (Z-axis) of a delivered one of said plurality of proton particle beams from the particle beam splitter.

16 . The apparatus according to claim 15 , wherein the support platform comprises a robotic chair configured to rotate or move the patient through 180° relative to a longitudinal axis (X-axis) and through 90° relative to the vertical axis (Z-axis) of the delivered one of said plurality of proton particle beams from the particle beam splitter.
