ABSTRACT:
The invention relates to an X-ray device including a number of components to each of which is assigned a data transmission node working by the CAN protocol whose data input and data output are in mutual communication with other data transmission nodes via transmitters and receivers, the data transmission nodes being connected to the relevant associated components through connection lines. A fast and reliable data transmission is safeguarded in that the transmitter and receiver of at least some of the data transmission nodes are constructed for wireless transmission, and in that these transmitters or receivers are so controlled that they send data to at least the wireless receivers of other data transmission nodes and receive data from the wireless transmitters of at least the other data transmission nodes, as applicable.
