Abstract
A method for delivering therapeutic radiation to a tumor within a patient including: monitoring tumor motion in a preliminary procedure to generate and record a surrogate signal representing the tumor motion; determining a radiation therapy plan for the patient including a planned sequence of varying parameters of a radiation beam to track the tumor motion and a planned rate of execution of the planned sequence; configuring a radiation therapy device to deliver radiation in accordance with the radiation therapy plan, positioning the patient within the device, and activating the device to perform the planned sequence; monitoring tumor motion during the procedure to provide a treatment surrogate signal; determining the difference between the estimated and treatment surrogate signals; and regulating the speed of the radiation treatment procedure by varying the rate of execution of the sequence of beam parameters in accordance with the difference between the estimated and treatment surrogate signals.
