First Claim
Patent Images
1. A method of delivering radiation therapy to a patient when a region of interest is moving, the radiation therapy being delivered by a radiation therapy system including a multi-leaf collimator, the method comprising:
- generating a treatment plan for delivering radiation therapy, the treatment plan including a series of machine instructions;
activating a radiation beam for delivering radiation therapy to the patient by following the treatment plan;
monitoring the patient while the radiation beam is active and delivering radiation to the patient; and
changing a leaf pattern of the multi-leaf collimator from the leaf pattern as specified by the treatment plan while the radiation beam is active based at least in part on the monitoring the patient,wherein the changing a leaf pattern includes reordering the machine instructions.
