Radiotherapy has a well-established role in the management of head and neck cancers. Over the past decade, a variety of new imaging modalities have been incorporated into the radiotherapy planning and delivery process. These technologies are collectively referred to as image-guided radiotherapy and may lead to significant gains in tumor control and radiation side effect profiles. In the following review, these techniques as they are applied to head and neck cancer patients are described, and clinical studies analyzing their use in target delineation, patient positioning, and adaptive radiotherapy are highlighted. Finally, we conclude with a brief discussion of potential areas of further radiotherapy advancement.
放射治疗在头颈部癌症的治疗中具有明确的作用。在过去的十年中，各种新的成像方式已经被纳入放射治疗计划和实施过程中。这些技术统称为图像引导放射治疗，可能会显著提高肿瘤控制率和降低放射副作用。在以下综述中，我们将描述这些技术在头颈部癌症患者中的应用，并强调分析其在靶区勾画、患者定位和自适应放射治疗中应用的临床研究。最后，我们简要讨论了放射治疗进一步发展的潜在领域。
