X-rays are electromagnetic waves which are produced with an X-ray tube for medical purposes. In German, they are named after Wilhelm Conrad Röntgen, who discovered them in 1895 in Würzburg. In the x-ray system, the x-rays developed by it are sent through the body area being examined, and then the photons let through are transmitted to a digital detector system for the development of an image. The dose is accurately recorded and documented.
The dose the patient is exposed to during an x-ray examination, is kept as low as possible. Compared with the early 20th century, less than 1 percent of the radiation dose needed at that time is needed today for creating an x-ray image.
The Radiologische Allianz has switched completely to digital radiography. The advantages are the lower radiation dose and the fact that it is possible to save the image in a digital archive. We can mostly forgo usual x-ray images. Patients will receive prints and a CD, on which the data are saved instead. So the patients can look at the results of their examination on any modern PC or tablet.
