Device for radiation therapy under image monitoring

A method for administering radiation therapy to an examination object implemented with image monitoring, comprising the steps of:

• exposing an examination object in a patient to therapeutic beams emitted by an exposure device;
• at least during a portion of a time during which said examination object is exposed to said therapeutic beams, acquiring magnetic resonance imaging data from the examination object with a magnetic resonance device having an examination volume in which the examination object is located, and generating a magnetic resonance image of the examination object from the magnetic resonance data using a magnet of said magnetic resonance device that generates a static magnetic field, said magnet comprising a bore in which said examination volume is located;
• locating a hardware component of said exposure device in said bore, and emitting said therapeutic beams from said hardware component of said exposure device into said examination volume of said magnetic resonance device;
• vertically supporting the patient on a patient support in an upright position while acquiring said magnetic resonance data and while exposing the examination object to said therapeutic beams, and rotating the examination object, relative to the magnetic resonance device and the exposure device, with the patient in said upright position on said patient support, around a vertically proceeding rotation axis;
• and
• orienting said magnet of said magnetic resonance device to surround or enclose at least a portion of said hardware component of said exposure device and at least a portion of said examination object with said hardware component in said static magnetic field.

A system for radiation therapy with image monitoring, comprising:

• a magnetic resonance device configured to generate magnetic resonance images of an examination object of a patient for image monitoring of the examination object of the patient located in an examination volume of the magnetic resonance device;
• a statically-mounted exposure device, comprising a hardware component that exposes the examination subject in the examination volume to therapeutic beams emitted from said hardware component;
• a patient support configured to support the patient and configured to cause the examination object to be rotated relative to the magnetic resonance device and to the exposure device around a rotation axis;
• and
• said magnetic resonance device comprising a magnet, which participates in generation of said magnetic resonance images by generating a static magnetic field, said magnet being configured to surround or enclose at least a portion of said hardware component of said exposure device and at least a portion of said examination object with said hardware component in said static magnetic field;
• and
• said magnet of said magnetic resonance device comprising a bore in which said examination volume is located, and said hardware component being located in said bore.
