An imaging device has a gantry that is movable along a floor, and a supply unit for transmission of power and/or data between a stationary supply source and the movable gantry. The transmission of the power and/or data takes place via wireless transmission elements. This wireless transmission of the power and/or data between the transmission elements can take place via conductor structures, and the wireless transmission elements are arranged in the floor of the room of the imaging device and in a sled of the movable gantry.
