中文摘要: |
图像引导是精准放射治疗用以定位肿瘤靶区以及周围危及器官的基本手段。与MR扫描仪相比,基于X射线成像的影像设备具有软组织对比度差和辐射性等缺点。因此将MR扫描仪与放射治疗机相结合的一体化、实时MRI引导的放射治疗(MRIgRT)技术成为放射治疗的一个新方向。本文就MRIgRT的技术优势,国内外相关MRIgRT设备的研发动态,以及MRI引导放射治疗的技术难点进行综述。 |
英文摘要: |
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. |
