3D High Speed RF Beam Scanner for Hadron Therapy of Cancer
Stanford researchers have developed a novel technique to control proton beams for radiation therapy to deliver a very high, full dose across a tumor in less than one second. This fast and powerful approach controls the lateral position and depth of penetration of proton beams using an RF accelerator mounted at the end of a gantry.
Overcoming challenges of existing systems, this new proton beam with its precision and compact footprint, enables FLASH delivery (very high dose rate, short duration) which is an emerging technique in radiation therapy. The flexible design is compatible with any proton source and can be retrofitted to existing systems.
