Abstract
A radiation irradiation method and an apparatus enables effective radiation irradiation even in the case of a diseased part changing its position due to physical activity, such as breathing and the heart beat of the patient, with a simplified apparatus. Initially, the position change of the diseased part and the physical activity of the patient are measured concurrently, and a relationship therebetween is defined as a corresponding function. Next, along with the detection of the physical activity of the patient, radiation therapy is performed, in which the control of the radiation irradiation is carried out in accordance with the corresponding function.
