Integrated external beam radiotherapy and MRI system

摘要

A radiation therapy system comprises a radiation source generating a beam of radiation and a magnetic resonance imaging apparatus. An interface acts between the radiation source and the MRI apparatus that permits irradiation to be performed simultaneously with imaging. The MRI apparatus and radiation source are coupled such that the system can be used in a rotation mode whereby the radiation source can irradiate a subject from basically any angle without reducing MRI image quality.

1. A radiation therapy system comprising:
a magnetic resonance imaging (MRI) apparatus; a radiation source capable of generating a beam of radiation, the radiation source including an accelerating waveguide; and a coupling to couple the radiation source and the magnetic resonance imaging apparatus such that they rotate in unison about an axis of rotation and the system can be used in a rotation mode, to permit irradiation of a subject from any angle simultaneously with imaging and without reducing magnetic resonance imaging image quality, wherein the accelerating waveguide is positioned to accelerate particles in a particle beam, such that the particle beam within the accelerating waveguide is perpendicular to the axis of rotation.
