CHARGED PARTICLE TRANSLATION SLIDE CONTROL APPARATUS AND METHOD OF USE THEREOF

摘要

The invention comprises a system for patient specific control of charged particles in a charged particle beam path using one or more trays inserted into the charged particle beam path, such as at the exit port of a gantry nozzle in close proximity to a tumor of a patient. Each tray holds an insert, such as a patient specific insert for controlling the energy, focus depth, and/or shape of the charged particle beam. Examples of inserts include a range shifter, a compensator, an aperture, a ridge filter, and a blank. Trays in a tray assembly are optionally retracted into an output nozzle of a charged particle cancer treatment system. Optionally and preferably, each tray communicates a held and positioned insert to a main controller of the charged particle cancer therapy system.

主权项

1. A method for adjusting a charged particle beam traversing along a charged particle beam path, comprising the steps of:
providing a charged particle system, comprising:
an accelerator;a beamline from said accelerator to an output nozzle; anda tray assembly; inserting a first tray into a first slot of said tray assembly, said first tray configured with a first insert comprising a patient specific charged particle beam adjustment material; and after said step of inserting, longitudinally retracting said tray assembly along the charged particle beam path into said output nozzle.
