The present application provides a plan adjustment method for radiotherapy, a radiotherapy system, and a related apparatus. The method comprises the following steps: S1, acquiring simulated CT information and treatment plan information of a patient, the simulated CT information comprising a simulated CT image and region division information corresponding thereto; S2, measuring, in the current session of radiotherapy corresponding to the treatment plan information, Cerenkov radiation emitted by the patient due to particle radiation exposure; S3, acquiring irradiation exposure dose information of an irradiation target region and an organ at risk in the treated region; S4, determining, according to the dose information of the target region and the organ at risk and the treatment plan, whether the treatment plan for subsequent irradiation fractions needs adjustment; and S5, if so, adjusting the treatment plan for subsequent fractions according to dose distribution of an irradiation exposure region and a therapeutic prescription corresponding to the patient. In the present application, the Cerenkov radiation emitted by the patient is detected to judge the quality of the treatment plan, which improves the accuracy of plan adjustments in radiotherapy and the safety of radiotherapy.
