1. A base for a mobile X-ray imaging system, the base comprising:
a carriage comprising a first end portion and an opposite second end portion, the first end portion configured as a front end arrangeable closer to an object during X-ray imaging than the opposite second end portion configured as a rear end, the first end portion and the opposite second end portion arranged along a longitudinal center line of the base;
a mounting structure mounted to the carriage, the mounting structure configured to movably hold an X-ray imaging device;
a wheel base with a wheel arrangement of at least three wheels, each of the at least three wheels mounted to the carriage to be pivotable around a vertical pivot axis and rotatable around a horizontal wheel axis,
wherein at least two of the at least three wheels forming at least two rearside wheels mounted in a region of the rear end and at least one of the at least three wheels forms a frontside wheel mounted in a region of the front end, each of the at least two rearside wheels independently actively steerable in an orientation around the vertical pivot axis and drivable around the horizontal wheel axis to move the base in relation to a floor;
a pivot actuator configured to independently actively steer each of the at least two rearside wheels to be pivoted in the orientation around the vertical pivot axis;
a drive actuator configured to independently actively drive each of the at least two rearside wheels to be rotated around the horizontal wheel axis; and
a wheel controller configured to control the pivot actuator to independently actively steer each of the at least two rearside wheels to be pivoted in the orientation around the vertical pivot axis and control the drive actuator to independently actively drive each of the at least two of the rearside wheels to be rotated around the horizontal axis to rotate the base around a virtual point of rotation that is aligned with the longitudinal center line of the base.
