Abstract
A method for planning a treatment session of a patient and optimizing the treatment time for a treatment using a radiation therapy system includes a radiation therapy unit having a fixed radiation focus point. During an optimization of a treatment plan for a patient, a set of shots to be delivered to a plurality of isocenter positions within a target volume of a patient during a treatment session are determined and a beam-on time for each respective sector and state for each isocenter during which radiation is to be delivered are determined based on the treatment plan. For each isocenter position, sectors and states of respective sector are grouped in accordance predetermined rules with respect to beam-on times for respective state of the sectors, wherein sectors and respective states are aggregated for simultaneous delivery of radiation during a predetermined period of time.
