A radiation therapy apparatus and method for applying radiation to a patient in synchronism with one of a plurality of states of a cardiac cycle and one of a plurality of states of a respiratory cycle of the patient. An electrocardiograph (1) and a respiratory monitor (3) are operatively connected to the patient. A controller (7) is provided for receiving an output from said electrocardiograph indicative of which of said plurality of cardiac cycle states the cardiac cycle is presently in and for receiving an output from said respiratory monitor indicative of which of said plurality of respiratory cycle states said respiratory cycle is presently in. A radiation applicator (9) applies radiation to the patient in response to a trigger signal from the controller, said trigger signal being generated by said controller in response to said output from said electrocardiograph and said output from said respiratory monitor.
L'invention porte sur un appareil de radiothérapie et un procédé d'application de rayonnement à un patient en synchronisme avec l'un des différents états de son cycle cardiaque et l'un des différents états de son cycle respiratoire. Un électrocardiographe (1) et un dispositif de surveillance de la respiration (3) sont reliés au patient pendant l'intervention. Un contrôleur (7) reçoit dudit électrocardiographe un signal de sortie indiquant celui des différents états du cycle cardiaque actuellement en cours, et reçoit dudit dispositif de surveillance de la respiration un signal de sortie indiquant celui des différents états du cycle respiratoire actuellement en cours. Un applicateur (9) de rayonnement applique un rayonnement au patient suite à un signal de déclenchement venant du contrôleur, ledit signal de déclenchement étant produit par ledit contrôleur en réponse au signal de sortie de l'électrocardiographe et au signal de sortie du dispositif de surveillance de la respiration.
