Abstract
A radiation therapy system has a radiation therapy planning CT system and a radiation therapy apparatus. The CT system includes a system control unit, a CT scanner unit, and a therapy planning portion. The collected data obtained by the CT scanner unit is output to the therapy planning unit. The therapy planning portion creates therapy planning data such as center projection images for when performing therapy and center projection images for when performing X-ray photography. On the other hand, the radiation therapy planning apparatus includes a central control unit, an apparatus proper, and a driving control unit. The driving control unit controls in real-time the period of irradiation of radiation based on the therapy planning data from the CT scanner unit,and the opening/closing of the collimator,according to the position of the marker,on the fluoroscopy image photographed by the X-ray TV. Such an arrangement provides a radiation treatment method and system which does away with deterioration in precision owing to bodily movement during irradiation.
