A mobile diagnostic imaging system comprises a rotatable portion and a non-rotatable portion, wherein the rotatable portion rotates with respect to the non-rotatable portion to obtain an image of an object. The system also comprises a power supply on the rotatable portion and a docking system that selectively engages to electrically connect the rotatable portion and the non-rotatable portion and prevent the rotatable portion from rotating with respect to the non-rotatable portion, and selectively disengages to electrically disconnect the rotatable portion and the non-rotatable portion during an image scan.
