呼吸运动是影响肺癌放疗效果的重要因素,同时它也是一个比较复杂和难于解决的问题。笔者将从呼吸运动过程中肺肿瘤的运动情况、呼吸运动对肺癌放疗的剂量学影响、肺癌放疗中呼吸运动问题的解决方法等方面来阐述肺癌放疗中的呼吸运动问题及解决方法。一、呼吸运动过程中肺肿瘤运 Respiratory movement is an important factor affecting the radiotherapy of lung cancer, but it is also a more complicated and difficult problem to be solved. The author will expound the problem of respiratory movement in radiotherapy of lung cancer and its solution from the aspects of the movement of lung tumor during respiratory movement, the dose-effect of respiratory motion on radiotherapy of lung cancer and the solution of respiratory motion during radiotherapy of lung cancer. First, lung cancer during respiratory movement
