Device for treating a patient's tumor with charged particles

摘要

An object of the invention is an apparatus for treating a tumor (2120) of a patient (2130) with charged particles, the apparatus comprising a charged particle bundle system (100); a support platform (3510) comprising a longitudinal support arranged to position the patient (2130) in a first position away from the charged particle paths and subsequently positioning the patient (2130) in a second position in the charged particle pathway; a synchrotron (130) arranged to supply charged particles to a position above the support platform (3510) in a second position; a pair of oscillating induction lamellae (1912, 1914) at a first distance from the center (280) of the synchrotron (130); extraction material (1930) less than 10 millimeters thick; a pair of extraction lamellae (1914, 1916) at a second distance from the center (280) and a vacuum tube (322) longitudinally surrounding the charged particle beam path, said vacuum tube (322) extending successively to the synchrotron (130); along the bundle circulation path (264); between a pair of oscillating excitation lamellae (1912, 1914); through said extraction material (1930), with subsequent retardation of charged particles into an extraction path with reduced arc radius (266) during use and between a pair of extraction lamellae (1914, 1916); said first distance being greater than said second distance; the synchrotron (130) is arranged to supply charged particles to a position above the platform (3510) in a second position.
