放射治疗过程中每次的治疗摆位决定了患者病灶受照射的位置,很大程度上影响着治疗的疗效,因此提高每次放疗位置精准性成为当前研究的热点。目前广泛使用图像引导技术(IGRT)来确保治疗位置的准确性,在病人量大的医院很难每次治疗前均进行体位验证,体位准确性得不到高效保证,笔者就治疗摆位误差的控制,结合3D成像摆位技术等发展进行综述。 Radiation therapy during the treatment of each set position determines the location of the patient’s lesion irradiation, largely affected the efficacy of the treatment, so to improve the accuracy of each radiotherapy position has become the current research hot spots. At present, IGRT is widely used to ensure the accuracy of the treatment position. It is difficult to verify the position of each patient before the treatment and the accuracy of the position can not be guaranteed efficiently. Therefore, Control, combined with the development of 3D imaging positioning technology for review.
