A mobile X-ray examination apparatus has an instruction receiving device that receives an entered instruction for the mobile X-ray examination apparatus to reach a designated position. A navigation device creates an environment map of an environment of the mobile X-ray examination apparatus, determines a current position of the mobile X-ray examination apparatus according to detected environment profile information, calculates a movement trajectory of the mobile X-ray examination apparatus according to the environment map, the current position and the designated position received by the instruction receiving device, and sends corresponding information to a central control device. The central control device causes the mobile X-ray examination apparatus to reach the designated position along the movement trajectory according to the corresponding information sent by the navigation device.
