<p>The present invention relates to a treatment system using a linear accelerator based on a guided magnetic resonance imaging (MRI) and, more specifically, to a treatment system using a linear accelerator based on a guided magnetic resonance imaging (MRI) which minimizes twists caused by magnetic field generated when the linear accelerator is combined with the MRI where according to an embodiment of the present invention, radiotherapy based on the MRI without twists enables patients to be hardly exposed to X-ray and leads to an accurate treatment for soft tissues. In addition, the treatment system minimizes influences of magnetic field generated by the MRI on the linear accelerator and is accordingly allowed to efficiently control an amount of X-ray radiated from the linear accelerator, thereby accurately performing radiotherapy. In addition, the treatment system can control the position and direction of the linear accelerator without any difficulty and accordingly radiates X-ray to a target to be treated in optimal positions and various angles, thereby performing efficient radiotherapy.</p> |
