Abstract: A mobile X-ray device with an adjustable recording system that is arranged on a device trolley is provided. The adjustable recording system has an X-ray source and an X-ray detector for recording X-ray images of an object. The mobile X-ray device includes a system controller for actuating the X-ray device, a calculation unit for real-time determination of a scattered radiation distribution from an X-ray radiation generated by the X-ray source in at least parts of the surrounding area of the X-ray device, and a display unit that is arranged on the device trolley and/or the recording system. The display unit is configured for display, taking place substantially in real time, of at least one item of information dependent upon the determined scattered radiation distribution in at least one part of the surroundings of the mobile X-ray device.
