Co-rotatable targeting apparatus and method of use thereof in conjunction with a charged particle cancer therapy system

摘要

A rotatable patient positioning apparatus and method of use thereof is described in combination with a rotatable magnet at a termination of a beamline arc. The rotatable patient positioning system optionally: (1) rotates a median of the person in place about a vertical axis and/or (2) rotates the entire person along a path around a vector, such as a vertical axis, where no part of the person intersects the vector. 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. The rotatable patient positioning system and targeting magnet combine to target the tumor in three-dimensions.

1. A method for positioning a tumor of a patient for treatment by positively charged particles, comprising the steps of:
accelerating the positively charged particles with an accelerator; transporting the positively charged particles from said accelerator to a rotatable magnet; rotating said rotatable magnet about a vertical axis; and co-moving, with rotation of said rotatable magnet, the patient along a path on a first platform around the vertical axis, the tumor not intersecting the vertical axis.
