Nowadays, the majority of people is aware of the risk posed by X-rays and the transmitted patient dose during X-ray scans has been significantly reduced in the past decades 1. X-ray-based foot scanners where still in use to measure foot sizes in shoe stores until the 1970s. Yet, the repair process sometimes fails which in some cases leads to an unregulated division of cells that might result in cancer. In most cases, the DNA will be repaired by the cell itself. Here, deoxyribonucleic acid (DNA) becomes damaged by the radiation. That means the radiation changes the atomic structure of the tissue which can potentially lead to an increased risk for the development of cancer. High energies emitted to the body during an X-ray acquisition can lead to ionization.

Further, dir point of rapid development is the awareness that X-rays can also be harmful.

In 1927, the company was bought and is today an integral part of Philips Medizin Systeme GmbH.įluroscopy allows for real time X-ray sequences which are often inevitable in minimally invasive interventions. Müller developed the first commercial X-ray tube in Hamburg, Germany, in cooperation with the University Clinic Hamburg-Eppendorf. 7.4 which was taken later in January of 1896. It is not to be confused with a similar image depicted in Fig. It depicts the hand of Röntgen’s wife, where we can clearly see the ring she was wearing on her annular finger. One of the first acquired X-ray images is shown in Fig. After that, he began a systematic study of the new radiation, which he then named “X”-rays. Additional experiments where he replaced the cardboard with denser materials, e. When moving the fluorescent screen away from the tubes opening he realized that there was still a glimmer visible on the fluorescent screen, which had to be the result from radiation that passes through the black cardboard. He further used a fluorescent screen and covered the actual tube with black cardboard.

On November 8, 1895, he conducted experiments including Crookes tubes, which are typically used to visualize streams of electrons. X-rays have been discovered by Wilhelm Conrad Röntgen in Würzburg, Germany.
