The X-ray was first invented by William Conrad Rontgen in 1895. He invented the x-ray by accident. He discovered an image from his cathode generator not knowing that it was an x-ray. Future investigation showed the rays were generated when the cathode ray beam on the inside of the vacuum tube, known as a radiograph. Lungs look black on an radiograph because the deal with air and air absorbs the least x-rays.
One week after the discovery of the x-ray, William took an x-ray of his wife’shand that revealed her wedding ring and her bones. The radiograph electrified the public and caused scientific interest in the new way of radiation.
William Coolidge invented the x-ray tube. Back then it was known as the Coolidge tube. His invention sparked the generation of x-rays also the model if which all x-rays tubes for medical had been based on. It took 25mins to get the photo on William’s wife hand.
One of the radiology departments in the world was Glasgow royal infirmary. This department was founded in 1896. The head of the department was john Macintyre. He produced many outstanding x-rays. The first x-ray was of a kidney stone. Even one with a child with a penny stuck in its throat. And last but not least one of a frog legs in motion. Dr. Hall was one of the first doctors to make a diagnostic x-ray which was a needle stuck in a women’s hand. It has been known that frequent exposure to x-rays can be harmful, and as of today they are ways to protect the patient and the dr. from extreme amounts of radiation exposure.
Rontgen discovery was labeled as a medical miracle and xrays to become a very important part of a diagnostic tool in medicine. The xray would aloe doctors to see inside the human body for the first time without having to...

...om dental X-rays is negligible. You receive more radiation by just being in the sun, than you do by going to your dentist. The benefits of dental X-rays are huge. In most cases we cannot see dental issues without them. With X-rays, we can catch that cavity well before you feel it. Without an X-ray, it could linger without any pain until the tooth becomes infected. Then you would generally have to get a root canal, or you would have to get the tooth pulled. So Xrays are very much worth getting.

In the radiology profession first you must write the patient’s file. This includes information about insurance, medical history, what the required x-ray is for and where it is going to be taken on the body. Writing in this way is similar to writing a small research paper. You must do research on the patients and there history and what insurance they have. Writing the report is important because the information must be accurate so the patient can be helped as much as possible. If the information about medical history is incorrect it can cause a huge problem for the patient. For example, if the patient is claustrophobic they would need to get an open room x-ray where the patient isn’t in an enclosed tube so they don’t have a panic attack and potentially injure themselves and others. It is very important to make sure the report has the correct area of where the x-ray needs to be taken. Having the wrong part of the body x-...
Apart of becoming a new patient at a dental office is taking an x-ray and some may have question along with taking an x-ray, like “will I be affected by the x-ray?” or “will I get cancer?”, “how long will it take” “are x-ray’s safe?”, the list goes on and on. So in this paper we will talk about different types of radiation affects such as affects on children and pregnant women as well as some things that may help reduce some of the radiation that may harm the human body.
Today I’m going to inform you about X-ray Technology its history and how it been advancing since it’s been invented. Also will inform you how it is currently helping doctors and their patients.
In 1895, Professor Wilhelm C. Roentgen, a German physicist, was working with a cathode ray tube, much like our fluorescent light bulb. The tube consisted of positive and negative electrodes encapsulated in a glass envelope. On November 8, 1895, Roentgen was conducting experiments in his lab on the effects of cathode rays. He evacuated all the air from the tube and passed a high electric voltage through it after filling it with a special gas. When he did this, the tube began to give off a fluorescent glow. Roentgen then shielded the tube with heavy black paper and discovered a green colored fluorescent light could be seen coming from a screen located a few feet away from the tube.
The X-ray was first discovered in 1895 by a German physicist named W.C. Roentgen (“The Discovery”). W.C. Roentgen was working in his lab one day in 1895 and decided to send a high electrical current through a cathode ray filled with special gas. He realized that a dim green colored light was being produced, and decided to hold the cathode ray just above his wife’s hand. When he did this he observed that the light was able to penetrate human skin, but would leave all the bones visible. There is a picture below of the X-ray of W.C. Roentgen’s wife’s hand (“The Discovery”). He named it the X-ray because he did not know the identity of what kind of ray it was. He just named it X, because of its use in solving unknowns in algebraic equations (“The Discovery”).
The role of the radiologist is one that has undergone numerous changes over the years and continues to evolve a rapid pace. Radiologists specialize in the diagnoses of disease through obtaining and interpreting medical images. There are a number of different devices and procedures at the disposal of a radiologist to aid him or her in these diagnoses’. Some images are obtained by using x-ray or other radioactive substances, others through the use of sound waves and the body’s natural magnetism. Another sector of radiology focuses on the treatment of certain diseases using radiation (RSNA). Due to vast clinical work and correlated studies, the radiologist may additionally sub-specialize in various areas. Some of these sub-specialties include breast imaging, cardiovascular, Computed Tomography (CT), diagnostic radiology, emergency, gastrointestinal, genitourinary, Magnetic Resonance Imaging (MRI), musculoskeletal, neuroradiology, nuclear medicine, pediatric radiology, radiobiology, and Ultrasound (Schenter). After spending a vast amount of time on research and going to internship at the hospital, I have come to realize that my passion in science has greatly intensified. Furthermore, both experiences helped to shape up my future goals more prominently than before, which is coupled with the fact that I have now established a profound interest in radiology, or rather nuclear medicine.
However, once the public caught wind of these magic rays, the x-rays popularity skyrocketed. Within 6 months after the announcement of the discovery of x-rays the United States and Europe had built many medical x-ray machines to aid in surgery, and even x-ray machines for the battle field, in which field medics would use the rays to locate bullets in the bodies of wounded soldiers. (1.) While the x-rays gained popularity in the minds of the people of the world, they did not sell well. Befor...
3-D scanning has helped improve orthodontics a lot with finding the problem and being able to understand the problem better. Also it can help see everything in your mouth that a regular x-ray cannot see.
Modern medicine is capable of treating a tremendous range of human disease and injuries, but the usefulness of all medical specialties depends on accurate diagnosis. Virtually every conceivable medical specialty relies on radiological technologies to provide formal diagnoses, making radiology one of the most important of all medical specialties. Radiologists enjoy some of the best working conditions in modern medicine and typically experience very positive employment conditions. Consequently, their services are generally in very high demand, with many starting out with six-figure annual incomes immediately after completion of their professional training.
One of the first inventions but more so of a discovery was the idea of nuclear fusion. It was discovered by a German scientist in february of 1939. This led to the invention of the atomic bomb. The atomic bomb was only used twice both times by the U.S. near the end of the war first on Hiroshima then on Nagasaki(Atomic Bomb).
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.
Wilhelm Roentgen discovered radiation which is also known as x-ray in 1895. Radiation is energy turned into waves or particles in
Before the discovery of X-rays in 1895, it was impossible to look inside human body, without causing harmful side effects. The famous quote of Anna Bertha Ludwig - “I have seen my death” is a testimony to this. In ancient times, the only way to study internal human organs was the dissection of dead bodies. Additionally, this was also subject to availability or religious beliefs. Leonardo da Vinci made 240 detailed sketches between 1510 and 1511, which were way ahead of their time. Unfortunately, it could not be published, except for a small amount in 1632. Images aide in visualization of illnesses (e.g. a malignant tumor), which are impossible to observe from outside of the body. A surgeon must know the various attributes of the tumor like location and size, before she can operate on it. Similarly an oncologist needs this information to decide the course of treatment e.g. tumor size and metabolic activity may be needed to determine the number of chemotherapy sessions. With images, all this information can be obtained without cutting open the patient. And what’s remarkable is that u...
Through the use of the microscope and the discovery of DNA, there were many advances in anatomy and physiology throughout the twentieth century to the present time. However, the early discoveries by Erasistratus and Herophilus as well as the others created a foundation for the future scientists to base their research off of, which impacted where we are today in the field and contributed to the great advances that have been made in anatomy and physiology.
From a discovery made by one of his associates, he patented the Edison effect (now called thermionic diode), which is the basis for all electron tubes. Edison will forever be remembered for his contributions to the incandescent light bulb. Even though he didn't dream up the first light bulb ever crafted, and technology continues to change every day, Edison's work with light bulbs was a spark of brilliance on the timeline of invention.
