Title:
RADIATION THERAPY SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2021/253256
Kind Code:
A1
Abstract:
The present disclosure is directed to a radiation therapy system. The radiation therapy system may comprise a magnetic resonance imaging (MRI) apparatus. The MRI apparatus may include a plurality of shielding magnetic coils, the plurality of shielding magnetic coils being arranged around an axis. The radiation therapy system may also comprise a radiation therapy apparatus, which includes a linear accelerator configured to accelerate electrons to produce a radiation beam, the linear accelerator being located between two neighboring shielding coils of the plurality of shielding coils, and a length direction of the linear accelerator being parallel with the axis. The radiation therapy apparatus may also include a deflection magnet configured to deflect the electrons emitted from the linear accelerator by a deflection angle in a first portion of a moving trajectory, the first portion of the moving trajectory being on a plane intersecting with a radial plane of the MRI apparatus.
