Title:
RADIATION THERAPY APPARATUS CAPABLE OF INDUCING MAGNETIC RESONANCE IMAGING AND CONTROLLING IN-VIVO DOSE
Document Type and Number:
WIPO Patent Application WO/2021/085905
Kind Code:
A1
Abstract:
The present invention relates to a radiation therapy apparatus and, more particularly, to a radiation therapy apparatus capable of inducing magnetic resonance imaging and controlling in-vivo dose, wherein the radiation therapy apparatus includes a magnetic field adjusting device, and thus can perform magnetic resonance imaging induction in a first time section by applying a first magnetic field required for the imaging induction and can perform therapy in a second time section by emitting radiation while applying a second magnetic field required for in-vivo dose control. The present invention provides a radiation therapy apparatus for performing radiation therapy on an object, comprising: a magnetic field generating unit for generating a magnetic field in a first area where the object is positioned; an imaging induction unit for performing magnetic resonance imaging induction on the object by using a magnetic field generated by the magnetic field generating unit; a radiation irradiating unit for performing therapy by irradiating an affected area of the object with radiation; and a magnetic field adjusting unit for adjusting the magnetic field generated in the first area, wherein the magnetic field adjusting unit adjusts, in a first time section, formation of a first magnetic field required for magnetic resonance imaging induction in the first area, and adjusts, in a second time section, formation of a second magnetic field required for dose control regarding the object in the first area.
