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 of the patient and one of a plurality of states of a respiratory cycle of the patient. An electrocardiograph is operatively connected to the patient and a respiratory monitor is operatively connected to the patient. A controller 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 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.

[ What is claimed is:] [1.] A radiation therapy apparatus for applying radiation to a patient in synchronism with one of a plurality of states of a cardiac cycle of the patient and one of a plurality of states of a respiratory cycle of the patient, comprising:an electrocardiograph operatively connected to the patient;a respiratory monitor operatively connected to the patient;means for interactively receiving user input indicative of a selected point or interval of time when a chosen one of said plurality of cardiac cycle states overlaps with a chosen one of said plurality of respiratory cycle states;control means supplied with the user input from the means for receiving, an output from said electrocardiograph indicative of which of said plurality of cardiac cycle states the cardiac cycle is presently in, and an output from said respiratory monitor indicative of which of said plurality of respiratory cycle states said respiratory cycle is presently in; andradiation application means for applying radiation to the patient in response to a trigger signal from said control means, said trigger signal being generated by said control means in response to said user input from the means for receiving, said output from said electrocardiograph, and said output from said respiratory monitor.
