Abstract
In an exemplary embodiment, a radiation detector for reception of the radiation emerging from the radiography subject delivers electric output signals corresponding to the received radiation profile, a scanner device rotates the radiographic unit about an axis which passes through the focus of the x-ray tube and approximately through the detector center, and a measured value processing and display unit determines and reproduces the x-ray shadow image corresponding to the scanning movement of the radiographic unit (1, 4). The processing and display unit is designed in the manner of a radar display apparatus in which a number of concentric image point circles are recorded, each of which, (for the case of a radiation detector consisting of a series of individual detectors), is locally associated with a specific individual detector and is modulated in its intensity corresponding to the output signals of the associated individual detector.
