Radiography

X-Ray Discovery

Discovered by Wilhelm Röntgen in 1895
accidentally, when performing experiments with cathode tubes and fluorescent screens
the “light” even illuminated the screen when the tube was placed into a box
he called this new type of radiation X-rays (X for unknown)
these X-rays could travel through all kinds of materials, at different material-specific attenuations

3D-angiographic room: C-arm with x-ray tube and image intensifier at both ends. By rotating the C-arm on a circle around the patient a series of radiographic images are acquired that are subsequently used to compute a 3D image of the blood vessels.
