Magnetic Resonance Imaging Guided Radiotherpy System

摘要

The present invention relates to a magnetic resonance imaging (MRI)-based radiotherapy system having a structure in which a radiation generating appliance for the linear accelerator (LINAC) treatment is installed in a circular magnetic field generating appliance for the MRI, so that a high dose rate can be maintained; an additional cooling system is not required; and the problem related to MRI arrangement can be solved. The MRI-based radiotherapy system includes: a circular magnetic field generating appliance having a bracket-shaped surface and comprising a magnetic field generating device respectively installed inside a circular body on both sides separated by bracket-shaped grooves; and one or more LINACs installed along the bracket-shaped circular groove.
