A radiotherapy device having a gantry rotatably mounted to the radiotherapy device with a bearing and a counterweight attached to the gantry. The counterweight has a spatial position relative to the gantry. The spatial position of the counterweight is movable. The device is configured to generate a compensating torque on the bearing, the compensating torque based on a movement of the spatial position of the counterweight, to balance the gantry. |
