摘　　要：目的探讨CT图像引导放疗治疗肺癌患者的疗效。方法选取2013年5月至2014年5月在我院治疗的36例肺癌患者，收集所有患者在不同放疗阶段的CT图像和动态透视数据，获取实际肿瘤GTv体积和运动情况，和患者放疗前的各项检查数据进行分析对比，并计算正常组织所受剂量范围和肿瘤大小变化。结果通过基于图像引导技术的肺癌自适应放疗使患者肿瘤GTV体积缩小，且正常肺组织受照剂量降低。结论肺癌的自适应放疗能确定GTV和精确定位，可有效解决分次治疗间的靶区运动问题，在提高肿瘤照射剂量的同时，有效降低同侧正常肺组织的受照剂量，使肺毒性降到最低，值得在临床上推广。Objective： To study the curative effect of CT image guided radiotherapy in the treatment of patients with lung cancer. Methods 36 cases of patients with lung cancer were selected from May 2013 to May 2014 in our hospital. Their CT image and dynamic perspective data in different phases of radiotherapy were collected to obtain the actual tumor GTV size and movement, and compared and analyzed the inspection data of patients before radiotherapy. Also, the dose range of normal tissue and tumor size were calculated. Results The tumor GTV volume was reduced in patients with lung cancer treated by adaptive radiotherapy based on the image guided technology and the exposure dose on normal lung tissue was reduced. Conclusion The adaptive radiotherapy of lung cancer can determine the GTV and position accurately, which can effectively solve the problem of target movement points between the treatments. As increasing exposure dose on the tumor, it can effectively reduce exposure dosage on the ipsilateral normal lung tissue to make the lung toxicity to a minimum. Therefore, it is worth popularizing in clinic.
