Abstract
A method may include identifying a time window of a procedure. The method may also include obtaining operational information of the time window. The operational information may include a limit of pulse repetition frequency (PRF) acceleration and a plurality of preliminary radio frequency (RF) PRFs. The method may also include determining a plurality of updated RF PRFs by updating the plurality of preliminary RF PRFs. A rate of variation between any two adjacent updated RF PRFs may be less than or equal to the limit of PRF acceleration. The method may also include causing an RF source to generate electromagnetic waves at the plurality of updated RF PRFs in the time window.
Claims20
A system, 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 plurality of preliminary radio frequency (RF) pulse repetition frequencies (PRFs);
- determining a plurality of updated RF PRFs based on the plurality of preliminary RF PRFs, wherein a rate of variation between any two adjacent updated RF PRFs is less than or equal to a rate threshold, or a difference between any two adjacent updated RF PRFs is less than or equal to a difference threshold;
- causing an RF source to generate electromagnetic waves at the plurality of updated RF PRFs so as to causing a radiation device to deliver one or more radiation pulses to an object;
