Abstract: A radiotherapy device, a computer-implemented method and a computer-readable medium are provided. The radiotherapy device comprises an accelerating structure, a magnetron and a controller communicatively coupled to the accelerating structure and the magnetron. The controller is configured to determine a predicted resonant frequency change of the accelerating structure based on an predicted operation of the radiotherapy device. The controller is further configured to adjust an output frequency of the magnetron by the predicted resonant frequency change.
