Research progresses of MRI-guided radiotherapy equipment / 中国医学影像技术

ABSTRACT

Being the basic means in accurate and precise radiotherapy, image-guided radiotherapy can target the tumor and visualize the adjacent organs at risk. Compared with MR scanners, imaging devices based on X-ray imaging have disadvantages such as poor soft tissue contrast and radiation. In recent years, the integrated and real-time MR imaging-guided radiotherapy (MRIgRT) technology, which combines MR scanner and the radiotherapy machine, open a new horizon in radiation therapy. The technical advantages of MRIgRT, the research status of MRIgRT equipment at home and abroad, and the technical challenges of MRIgRT were reviewed in this article.
