【摘要】 国内恶性肿瘤患者病例数越来愈多,死亡率也居高不下。放射治疗是目前治疗癌症的三大有效方式之一,放疗环节中的质量保证和质量控制对于提高肿瘤患者的治愈率有重要的作用,先进的图像引导下的放疗技术能够在治疗过程中准确的核定治疗的位置,保证剂量投射的精度,较大程度的提高了肿瘤患者的治疗效果。同时放疗计划的二维及三维模体剂量验证也是质量保证的重要部分,其在一定程度上确保放疗物理师设计的放疗剂量与直线加速器出束的剂量能相对一致。如何精确有效地保证放疗各环节中的治疗质量是放射治疗界的重点研究方向。本文主要探讨目前放射治疗中图像引导技术实施及放疗计划剂量验证中的质量保证与控制,同时针对日新月异的设备与技术,探索新的放疗质量保证措施。更多还原

【Abstract】 The number of cases of malignant tumors in China is increasing, and the mortality rate is also high. Radiation therapy is one of the three effective ways to treat cancer. Quality assurance and quality control of the radiotherapy play an important role in improving the cure rate of cancer patients. The advanced image-guided radiotherapy technology can accurately verify the position of the treatment during the treatment process, ensure the accuracy of the dose projection, and greatly improve the treatment effect. At the same time, the two-dimensional and three-dimensional phantom dose verification of the radiotherapy plan is also an important part of the quality assurance, which ensures that the radiotherapy dose designed by the radiotherapy physicist is relatively consistent with the dose of the linear accelerator. How to accurately and effectively ensure the quality of treatment in all aspects of radiotherapy is the key research direction of the radiotherapy community. This article mainly discusses the current quality assurance and control in the image-guided technology implementation and dose verification in radiotherapy, and explores new radiotherapy quality assurance measures for the ever-changing equipment and technology.更多还原
