The disclosure relates to a medical imaging apparatus, and more particularly, to a mobile computed tomography apparatus for generating X-ray tomography images, and a method of controlling the mobile computed tomography apparatus. The medical imaging apparatus includes a gantry that is moveable； a moving device configured to move the medical imaging apparatus that includes the gantry； a damper configured to attenuate vibration generated by a movement of the gantry or a movement of the medical imaging apparatus； an inputter configured to receive an image capturing protocol for an object； and a controller configured to determine a coefficient of the damper for attenuating the vibration generated by the movement of the gantry or the movement of the medical imaging apparatus corresponding to the input image capturing protocol, and to apply a current to the damper to operate the damper according to the determined coefficient of the damper.
