A radiation protection device attaches to the C-arm of a fluoroscope and shields and collimates the X-ray beam between the X-ray source and the patient and between the patient and the image intensifier. A graphical user interface displays the received message data and allows the user to view and designate one or more target applications for processing the message data. Corrosion inhibitors are also compatible with the solution. On basis of comparison between information extracted on basis of the first set of signals and the second set of signals, respectively, at least one specific target is distinguished from other reflective objects.
