Some aspects include a system (100) and method (500) for receiving (510) an indication of occurrences of a substantially periodic treatment opportunity for a target volume of a patient from a motion detection device, the treatment opportunity being a period of time the target volume is in a position to be irradiated according to a burst mode treatment plan to be administered by a radiotherapy device； determining (S515) a future treatment opportunity for a target volume of a patient； beginning synchronization (S520) of a prescribed delivery period of burst mode irradiation and the future treatment opportunity； presenting (S535), to the patient, an indication of timing data indicative of a time until the prescribed delivery period of burst mode irradiation will occur； and irradiating (S545) the target volume during the synchronization of the future treatment opportunity and the prescribed delivery period of burst mode irradiation.
