Abstract
The invention relates to a radiodiagnostic system with an x-ray tube, flat picture intensifier, a coupled television camera system, a central unit and a monitor, wherein an image storage panel is connected to the television camera system and to the monitor and is coupled by its clock input with the central unit. At the central unit setting means are provided which act on the central unit in such a way that the vertical-to-horizontal frequency ratio of the television camera system is reduced by a factor N, the ratio of the image element clock frequency of the image storage panel to the horizontal frequency is increased by the same factor N, and the read-in process into the image storage panel is delayable in row and/or column direction, so that only a selectable image detail is displayable on the monitor.
