肝癌图像引导放疗研究进展

Research progress of image-guided radiation therapy for hepatocellular carcinoma Zhou Qingxiang, Wang Jianting, Zhai Fushan

肝癌是一种常见的恶性肿瘤，其预后较差，病死率较高。受呼吸动度影响，肝癌的摆位误差较大，肝癌图像引导放疗是将放疗机与影像设备结合在一起，监测和校正治疗时由于器官运动和摆位不确定造成的误差，从而提高放疗的精确性。

Hepatocellular carcinoma is a common malignant tumor, which has a poor prognosis and a high mortality rate. Under the influence of respiratory motion, the position error of liver cancer is relatively high. The image-guided radiotherapy is a combination of radiotherapy and imaging device, which can detect and correct the error caused by the movement of the organs and the position of the pendulum to improve the accuracy of radiotherapy.
