1. An X-ray device for producing X-ray images in cine mode, comprising an X-ray tube and an image intensifier/pick-up chain, including an X-ray image intensifier, an image pick-up system with at least a first and a second image sensor, an image processing system, and an optical beam splitter which is arranged between the image intensifier and the image pick-up system in order to image an exit screen of the image intensifier on the image sensors, characterized in that the image pick-up system comprises a control circuit for alternatively sensitizing the image sensors to receive successive fields of image information at alternative image sensors and for interleaving the fields of image information received by the image sensors to produce X-ray images in cine mode at an image field rate higher than the image field rate at which each one of the image sensors is receiving image information.
