Abstract：
Recent years have seen both a fresh knowledge of cancer and impressive advancements in its treatment. However, the clinical treatment paradigm of cancer is still difficult to implement in the twenty-first century due to the rise in its prevalence. Radiotherapy (RT) is a crucial component of cancer treatment that is helpful for almost all cancer types. The accuracy of RT dosage delivery is increasing as a result of the quick development of computer and imaging technology. The use of image-guided radiation (IGRT) has improved cancer outcomes and decreased toxicity. Online adaptive radiotherapy will be made possible by magnetic resonance imaging-guided radiotherapy (MRgRT) using a magnetic resonance linear accelerator (MR-Linac), which will enhance the visibility of malignancies. This review\'s objectives are to examine the benefits of MR-Linac as a treatment approach from the perspective of various cancer patients\' prognoses and to suggest prospective development areas for additional study.
摘要：
近年来，人们对癌症有了新的了解，并在治疗方面取得了令人印象深刻的进步。然而,由于癌症患病率的上升，癌症的临床治疗模式在二十一世纪仍然难以实施。放射治疗（RT）是癌症治疗的重要组成部分，对几乎所有癌症类型都有帮助。由于计算机和成像技术的快速发展，RT给药的准确性正在提高。图像引导辐射（IGRT）的使用改善了癌症的预后并降低了毒性。使用磁共振直线加速器（MR-Linac）通过磁共振成像引导放射治疗（MRgRT）将使在线自适应放射治疗成为可能，这将提高恶性肿瘤的可见度。这篇综述的目的是从各种癌症患者预后的角度研究MR-Linac作为一种治疗方法的益处，并提出进一步研究的前瞻性发展领域。
