Abstract
In an exemplary embodiment, a timing device sets the fluoroscopy time, and a program setting and display device displays the instantaneous values of the fluoroscopy voltage and current. An arithmetic unit is provided to which signals are supplied which correspond to the fluoroscopy voltage, the fluoroscopy current, and the fluoroscopy time, and which is so designed that it forms the arithmetic mean values of these quantities and brings them to display.
Claims4
In an x-ray diagnostic installation comprising a timing device (18) for determining the fluoroscopy time, and programming and display means (21) for preselection of desired fluoroscopic parameters and display of instantaneous values of such fluoroscopic parameters, the improvement comprising an arithmetic unit (17) having means (15) for supplying thereto signals corresponding to the fluoroscopy tube voltage, the fluoroscopy tube current, and a measure of the fluoroscopy time, and being operable to form the arithmetic mean values of tube voltage and current and to effect the display of such mean values.
