1895 – X-rays were discovered accidentally by physicist Wilhelm Conrad Rontgen. Rontgen was working on a experiment and testing whether cathode rays could pass through glass. He noticed that a nearby tube emitted fluorescent glow of crystals. The air in the tube was released, high voltage applied, the same tube emitted a fluorescent glow. When Rontgen covered the tube in a heavy black paper, a green light could be seen. He concluded that a new light ray was being broadcast. Rontgen discovered that the light was very powerful and the same ray could pass through human tissue, but not through bones and metal objects. Medical applications were soon to follow.

What would Wilhelm Roentgen, the father of X-ray, say about the technological discoveries in radiology today? Since the start of X-rays in 1895 significant advancements have revolutionized the field of radiology. One illustrates how different scanners have improved, in addition how picture archiving communication system can assist doctors, and finally the outlook on the future of radiology.
5-X-rays: - Even though the X-ray expose patient to harmful radiation it is used to see inside the human body and diagnose broken bones, gallstones and later tuberculosis.
X-rays have numerous different effects on the tissues of the body, depending on the time of exposure and energy of the X-ray photons. Best contrast between different tissues is when the photon energy is about 30 keV, for diagnostic purposes. Resulting in the photoelectric effect dominating at this energy. The tissues absorb X-rays and electrons are released. The X-ray absorption depends on the number of protons in the nuclei of the atoms encountered. A high number will attenuate the beam, producing a strong x-ray shadow, enabling for a high quality image of
The X-ray was first discovered in 1895 by a German physicist named W.C. Roentgen (“The Discovery”). W.C. Roentgen was working in a lab one day in 1895 and decided to send a high electrical current through a cathode ray filled with special gas. He
A scientist would need a glass tube with positive and negative electrodes. The tubes were called cathode tubes, and they were common in the late 1890s. The air leaves the glass tube, and a florescent glow is produced when a high voltage runs through the tube. The scientist needs to cover the glowing tube with a heavy, black paper or cardboard. Then the scientist will see the green colored fluorescent light illuminating from the box. This is known as the X-Rays which energizes the phosphorescent materials in the room. The newly discovered ray would pass through objects, and it can cast a shadow of most solid objects. The ray consists of electron passing through the matter underneath the cathode tube. It can pass through human tissues, but it cannot pass through bones and metal
Röntgen used a vacuum tube that is used in a cathode ray that was covered tightly with a thin black piece of cardboard and placed it in a dark room. As a discharge on a screen covered with fluorescent barium platinum cyanide, which was placed near the device, he recorded the bright glow. He found out that the fluorescence happened by an agent which could infiltrate from within the vacuum tube. This was impermeable to visible or ultraviolet radiation. He named the agent as x-rays or Röntgen rays. He then found out that x-rays could pass through solid
After receiving the document Yagoda already noticed uneasiness whether the title should be hyphenated or not. However, Yagoda’s explores the word written differently “x ray,” “x-ray,” “X-ray” and “X ray.” The life of the word x ray started on November 8, 1895 when Wilhelm Conrad Röntgen coined the name “X-Strahlen” for his discovery of radiation. The New York Times translated the word as X-rays in 1896, explains Yagoda. Shortly after introducing the word, the New York Times used the word without a hyphen. The newspaper gradually returned hyphen in 1920s. Yagoda wrote to the author of the document who replied on the practice in the physics community to use “x ray” when referring to the radiation we call “x.” It was an example that even physicists could not spot the various nuance. He also said “editors convert all his spellings ‘x ray’ to ‘x-ray’ or to
Radiology was invented in 1895 when Wilhelm Röntgen, a German Physicist, discovered x-rays. The technology
The first invention of radiology began with the creation of X-rays in 1895 when Wilhelm Roentgen, a 50-year-old professor of physics at Germany’s University of Wurzburg, made a discovery that would in a very short time change medical and human history. Though, discovered by accident, Roentgen’s
Rontgen was born on March 27, 1845. Wilhelm was a German Physicist. He was also the first person to detect electromagnetic radiation in a wavelength range, today known as x-rays. Rontgen earned the Rumford Medal of the Royal Society of London in 1896 and the first Nobel Prize in Physics in 1901. People also know him for his discoveries such as electricity, mechanics, and heat.Rontgen was born on March 27, 1845. Wilhelm was a German Physicist.

The discovery of x-rays revolutionized the entire medical profession, and provided a basis for diagnostic radiology. The x-ray showed the internal structures of the human body, without having to resort to surgery. Roentgen’s discovery of x-rays was a discovery that would benefit mankind for years.
The X-Ray was invented in 1895 by Wilhelm Conrad Roentgen. It all started with a vacuum tube called a Crookes tube, with this Roentgen noticed that by pressing a button that activated an electric current through it a shadow was projected onto a screen that showed the photograph of his wife’s hand with a ring
During the cold winter of 1895, a German scientist by the name of Wilhelm Conrad Roentgen was working with a cathode-ray tube when he noticed nearby crystals were glowing. When Roentgen reached for the crystals he was amazed when the shadow cast on the crystal was not of his whole
During an experiment he placed his hand between the source of the X-ray, the cathode-ray tube and a screen and saw the faint outline of the bones of his hand. It was the first X-ray picture. The more dense bone absorbed more X-rays then the less dense flesh producing an image of his hand. He soon learned that photographic plates were sensitive to X-ray as they are to light and was thus able to make the first X-ray photography. These first "Roentgen exposures" were of various metal objects that were locked in a wooden case and of his wife's hand.
