A vibration control apparatus may include a fluid bearing provided around a rotating body to form a fluid bearing gap between the fluid bearing and the rotating body and/or a pressure regulator configured to variably control a pressure of the fluid bearing, based on imbalance information of the rotating body, to compensate for imbalance of the rotating body. A computed tomography scanner may include a gantry configured to generate a computed tomography image while rotating around a test subject a fluid bearing provided around the gantry to form a fluid bearing gap between the fluid bearing and the gantry and/or a pressure regulator configured to variably control a pressure of the fluid bearing, based on imbalance information of the gantry, to compensate for imbalance of the gantry.
