ROTATABLE TARGETING MAGNET APPARATUS AND METHOD OF USE THEREOF IN CONJUNCTION WITH A CHARGED PARTICLE CANCER THERAPY SYSTEM

摘要

A rotatable targeting magnet apparatus and method of use thereof is described where the rotatable targeting magnet rotates independently of a beamline arc at the end of the beamline arc, where the arc is after an accelerator and before the patient in a cancer therapy system. The rotatable targeting magnet directs the charged particle beam, such as vertically, using applied current to the targeting magnet while rotation of the magnet allows scanning across the tumor. Rotation of the patient relative to the charged particle allows distribution of trailing Bragg peak energy within and/or circumferentially about the tumor.

1. An apparatus for guiding positively charged particles traversing a beam path toward a tumor of a patient, comprising:
a charged particle cancer therapy system, comprising:
an accelerator configured to accelerate the positively charged particles; anda beamline configured to transport the positively charged particles from said accelerator, said beamline comprising an arc, said arc comprising a final portion, said final portion of said beamline comprising:
a penultimate magnet; anda final magnet, wherein a line running from a central point of said penultimate magnet to a central point of said final magnet comprises a downward/non-vertical vector, said final magnet rotatable through at least ninety degrees about a vertical axis.
