<p>1. X-ray diagnostic equipment with a visual display device (5) having : at least one image store (12) ; a differential stage (13) for generation of substraction images by forming the difference between a stored video signal and a video signal following in time said stored signal ; an evaluation circuit (14 to 21) for time evaluation of the difference signal ; and a colour monitor (7), in which the evaluation circuit (14 to 21) comprises a timer (15) and a colour converter (14), characterized in that, the colour converter (14) is connected directly to the differential stage (13) and converts the difference image into a monochromatic intensity image, the image colour of which, dependent on the temporal occurence of the difference image, is controlled by the timer (15), in that the colour converter (14) has for each primary colour (r, g, b) an output and that at the ouputs of the colour converter (14) there are coupled respective stores (16 to 18) in which the output signals of the colour converter (14) are stored in an additive manner.</p> |
