Title (EN) MOVING BODY TRACKING DEVICE FOR RADIATION THERAPY
(FR) DISPOSITIF DE SUIVI D'UN CORPS EN MOUVEMENT POUR LA RADIOTHÉRAPIE
(JA) 放射線治療用動体追跡装置
Abstract:
(EN) By providing a synchronous controller that performs timing control of radiating or stopping radiation from the radiation source of a radiation therapy device and the radiating of x-rays from the x-ray tube of an imaging system, it is possible to eliminate wasteful irradiation by the synchronous controller performing timing control in a manner so that the radiating of x-rays (from the x-ray tube) and the radiating of radiation (from the radiation source) do not overlap. Furthermore, preferably, it is possible to eliminate overlapping radiating time and non-radiating time periods by setting an extension time (x, y, X, Y) and returning by temporally advancing by the extension time (x, y, X, Y).
(FR) Il est possible, par la fourniture d'un organe de commande synchrone qui réalise une commande de synchronisation de l'irradiation ou de l'arrêt de l'irradiation de la source d'irradiation d'un dispositif de radiothérapie et l'irradiation des rayons X du tube à rayons X d'un système d'imagerie, d'éliminer l'irradiation excessive grâce à la commande de synchronisation réalisée par l'organe de commande synchrone de manière à ce que l'irradiation des rayons X (du tube de rayons X) et l'irradiation de rayonnements (de la source de rayonnement) ne se chevauchent pas. En outre, et de préférence, il est possible d'éliminer les périodes de chevauchement de la durée d'irradiation et de la durée sans irradiation en définissant une durée de prolongement (x, y, X, Y) et le retour en avançant dans le temps de la durée de prolongement (x, y, X, Y).
(JA)  映像系のX線管からのX線の照射と、放射線治療装置の放射線源からの放射線の照射または停止のタイミング制御を行う同期コントローラを備えることで、(X線管からの)X線の照射と(放射線源からの)放射線の照射とが重複しないように同期コントローラはタイミング制御を行い、無駄な被曝をなくすことができる。さらに、好ましくは、遅延時間x,y,X,Yを設定し、遅延時間x,y,X,Yだけ時間的に前にずらして戻すことで、重複照射時間や無照射時間帯をなくすことができる。
