Abstract

The invention relates to a combined radiation therapy and magnetic resonance unit. For this purpose, in accordance with the invention a combined radiation therapy and magnetic resonance unit is provided comprising a magnetic resonance diagnosis part with an interior, which is limited in radial direction by a main magnet, and a radiation therapy part for the irradiation of an irradiation area within the interior, wherein at least parts of the radiation therapy part, which comprise a beam deflection arrangement, are arranged within the interior.

Claims15

Dependent claims

A passive beam deflection arrangement for deflecting a beam of charged particles in a main magnetic field, comprising:

a plurality of dipole deflection units,
wherein each of the dipole deflection units generates a dipole magnetic field substantially perpendicular to a path of the beam of charged particles passing through the dipole magnetic field,
wherein the beam of charged particles enters a first of the dipole deflection units parallel to an axis of the main magnetic field and is deflected by the deflection units away from the axis, and
wherein the beam of charged particles leaves a final of the dipole deflection units perpendicular to the main magnetic field.
