Abstract:
Cone-beam computed tomography (CBCT)-guided radiotherapy has been widely used in radiotherapy, but it still has many limitations.Using magnetic resonance imaging (MRI) instead of CBCT for imaging-guided radiotherapy can not only make use of the advantages of MRI, but it also allows for online and real-time tracking of tumor motion and biological changes.This technique truly realizes the real-time MRI-guided adaptive radiotherapy (ART) in anatomy and biology, and sets another milestone in the advancement of radiotherapy.This review summarizes the technical advantages of MRI-guided radiotherapy, the basic structure and type of MR-Linac, and the technical difficulties and solutions of MRIgART.
