| Research Abstract |
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.
