Abstract
A hadron therapy system that provides 3D scanning and rapid delivery of a high dose. Such systems can include a hadron source and accelerator with an RF energy modulator and an RF deflector that operate in combination to provide 3D scanning of a targeted tissue. The systems can include a permanent magnet quadrupole for magnification of the beam. The systems can include high energy hadron sources that utilize a multi-cell, multi-klystron design that achieves scanning of high energy hadron beams, for example a fixed energy of 200 MeV protons. Such systems can provide full irradiation of a liter scale tumor within one second or less.
Claims14
A treatment system that directs a hadron therapy beam to a target, the system comprising:
- a hadron source and accelerator providing the hadron beam at a desired energy level;
- an RF energy modulator disposed along a beamline of the hadron beam;
- an RF deflector disposed along the beamline, the RF deflector configured to scan the hadron beam transversally;
- and
- a magnetic quadrupole disposed along the beamline.
