Patent ID: 8766217

Claim:
A method for irradiating a tumor of a patient with charged particles, comprising the steps of: delivering the charged particles with a charged particle therapy system, comprising: a synchrotron; an extraction foil; a charged particle beam path; and a rotatable platform, wherein said charged particle beam path runs through said synchrotron and above said rotatable platform; controlling intensity of the charged particles using a current originating at said extraction foil, said extraction foil positioned in the charged particle beam path after entry into said synchrotron and prior to a Lambertson extraction magnet, wherein electrons of said current originate in atoms of said extraction foil; actively scanning the charged particles along at least three axes, wherein said at least three axes comprise: a horizontal axis, a vertical axis, and an applied energy axis; during an irradiation period, rotating said rotatable platform to at least five irradiation positions covering at least ninety degrees of rotation of said rotatable platform; timing delivery of the charged to the tumor using a respiration signal, wherein a respiration command is sent to the patient using a display monitor, said display monitor configured to co-rotate with said rotatable platform, said respiration signal monitor respiration of the patient; and irradiating the tumor with the charged particles during each of said at least five irradiation positions.
