Claim 12:
13. A system for controlling radiation output, comprising:
one or more storage devices comprising a set of instructions; and
one or more processors configured to communicate with the one or more storage devices, wherein when executing the set of instructions, the one or more processors are directed to cause the system to perform operations including:
obtaining a forward window, the forward window being at least a portion of a treatment plan that has not been performed;
obtaining forward information of the forward window, the forward information including time information of the forward window, a target dose relating to the forward window, and a dose per pulse (DPP) relating to the forward window;
determining a pulse repetition frequency (PRF) of the forward window based on the DPP, the target dose, and the time information of the forward window;
obtaining a pulse sequence pattern, wherein the pulse sequence pattern includes a plurality of pulse sequences during a period of time, each of the plurality of pulse sequences corresponding to a specific PRF, each of the plurality of pulse sequences including a plurality of pulses and a generation time of each of the plurality of pulses;
