A modulator for radiation therapy provides modulation of an area beam to decrease treatment time. Separate channels passing modulated 'beamlets' are possible by spacing the channels such that spreading of the beams and multiple angles of treatment eliminate cold spots. The space between the channels allows well-defined channel walls and space for modulator mechanisms.

Areal modulator for intensity modulated radiation therapy

An improved beam forming system for ions used in radiation treatment employs a magnet system of successive quadrupole magnets to convert an ion pencil beam to a fan beam with reduced neutrons production compared with conventional beam spreading techniques using scattering foils.

Ion radiation therapy system having magnetic fan beam former

A modulator for ions such as protons employs multiple shutter pairs to create independently movable apertures effecting a multiple pencil beam treatment of the patient thereby increasing treatment speed by eliminating the need for a custom compensator.

Scanning aperture ion beam modulator

A phantom for heavy ion radiation therapy provides characterization of an ion beam that may enter but not exit from the phantom. The phantom may include multiple materials and multiple spatially dispersed ion detectors to obtain signals that may be fit to known beam curves to accurately characterize the location and other parameters of Bragg peak of a given ion beam within a patient.
