ABSTRACT:
An X-ray device comprising an image pick-up system with at least two image sensors (11 and 12) and a control circuit (41) arranged so that the image sensors are not simultaneously but alternately sensitized in the cine mode. This arrangement enables the number of object images picked up per second to be increased in comparison with a similar system in which the sensors are simultaneously sensitized. When CCD sensors are used, the control circuit can also be arranged so that the integration time of the sensors becomes adjustable. These two steps reduce motion artefacts in images of quickly moving objects, for example images of a moving heart.
