We analyzed the 4D movement during 20 seconds in the same position as during radiotherapy of esophageal cancer, breast cancer, gastric cancer, and lung cancer. In esophageal, gastric, and lung cancer, after all breathing-related movement was bigger as the lesion which was near to diaphragm. In breast cancer, the breathing-related movement was around 2mm much smaller than expectation. I was able to show useful data in case of the internal margin decision in radiotherapy planning. This is a particularly important data in the treatment plan of IMRT(intensity modulation radiation therapy) becoming mainstream of the future radiation therapy.

我们在20秒内与食管癌，乳腺癌，胃癌和肺癌相同的位置分析了4D运动。在食管，胃癌和肺癌中，毕竟与呼吸有关的运动较大，因为病变接近隔膜。在乳腺癌中，与呼吸有关的运动比预期小得多2mm。如果放疗计划内部保证金决策，我能够显示有用的数据。这是IMRT（强度调节辐射疗法）的治疗计划中特别重要的数据，成为未来放射疗法的主流。
