A method and apparatus for controlling a vehicle are disclosed. The method comprises acquiring an acceleration of a front wheel and a rear wheel, determining that the front wheel is passing a bump of a road in response to determining that the acceleration of the front wheel is outside an acceleration range and fluctuates in the range wider than the acceleration range within a first maximum time period, determining that the rear wheel is passing the bump in response to determining that the acceleration of the rear wheel is outside the acceleration range and fluctuates in the range wider than the acceleration range within a second maximum time period, and in response to determining that the front wheel has passed the bump and the rear wheel is passing the bump, controlling a drive unit of the vehicle.

Disclosed are a radiotherapy assistant apparatus for modulating a build-up region of a photon beam for a radiotherapy, a radiotherapy system including the radiotherapy assistant apparatus, and method for the radiotherapy system. The radiotherapy assistant apparatus for modulating a build-up region of a photon beam for a radiotherapy, including at least: a magnetic field generator that generates a magnetic field that has a direction perpendicular to a movement direction of the photon beam, the magnetic field generator is disposed on a movement route along which the photon beam moves toward a target portion of the radiotherapy; and a magnetic field intensity adjuster that adjusts an intensity of the magnetic field generated by the magnetic field generator. The magnetic field generator disperses secondary electrons that have particular energy levels equal to or lower than a preset value.
