Internal Systems Disadvantages

- 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.

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.

→ An X-ray is an imaging test that uses small amounts of radiation to produce pictures of the organs, tissues, and bones of the body. When focused on the chest, it helps to spot abnormalities or diseases in the lungs.

I need to understand the detrimental danger involved in taking an x-ray. X-rays are just another form of electromagnetic radiation. X-rays are very similar to microwaves, radio waves and infrared radiations but x-rays are far more active compared to these other radiations. They penetrate many materials to varying degrees. Electrons with high energy crash into the target to produce x-rays. X-rays are transmitted through a subject onto a photographic film. The x-rays are blocked by bone and other solid objects casting a shadow onto the film. X-rays are used for a variety of things like; a x-ray could check for fractured or broken bones, scanning luggage at an airport, examining teeth and to see something in the body that could have potentially be swallowed.

The story of radiology started in 1895 when Wilhelm Conrad Röntgen made the discovery in November of 1895. While working with his Cathode Ray generator Röntgen noticed the ability to view an image using electromagnetic radiation. To test his discovery Röntgen performed an X-Ray on his wife’s hand which revealed that the ray could pass through human tissue leaving the bones and metals to show. In December of 1895 Röntgen published his manuscript “On a New Kind of Ray” to the Wurzburg Physical Medical Institute. His discovery was quickly transmitted throughout the world and his experiment was easily repeated due to the fact that many places had the Cathode Ray readily available. As the results began to improve and become more accurate, so did the technology allowing the radiographs that were made on glass photographic plates be replaced by film; a contribution made my George Eastman in 1918.The first radiology department of the world opened up at Glasgow Royal Infirmary in 1896 and in the same year came the first diagnosis by Dr. Hall-Edwards. Growing knowledge made it

Using X-rays for medical imaging is one of the most useful pieces of medical technology available when trying to determine and locate, the type and severity of a particular injury. X-rays are a form of electromagnetic radiation similar to visible light. However, unlike visible light x-rays can pass through most objects, including the body (NIBIB, n.d). The radiation hits a detector on the other side of the patient and the image produced is a shadowed representation of the tissues and structures in the body (NIBIB, n.d). However, due to the type of radiation being superimposed over the body it is worrying knowing that this form of radiation can, in some cases, cause some very life threatening mutations. The term used to describe the effective

This episode starts off by explaining what x-rays are and how they are most commonly used. X-rays are high-frequency electromagnetic waves. Medical institutions utilize these waves in a machine that releases x-rays and then captures the remainder. Because heavy atoms such as that found in bones and organs absorb x-rays, their "shadows" are left on the film. Although x-rays can be of great assistance in the medical world, they also help scientists explore the smallest particles and the vast corners of the universe.

On November 8, 1895, a German physics professor named Wilhelm Roentgen discovered x-rays. This advance in technology helped man explore the unknown of the human body without performing surgery. Only the microscope could compete with x-rays in the “contribution to medical vision” (Gunderman 2). After the discovery of x-rays, researchers found that there were therapeutic and also cancerous results from radiation emissions. Before this discovery became public, the Radium Watch Company began coating their watch dials with radium in order for them to glow, to allow owners of these watches see the time, even at night. However, the women workers, as watch dial painters, at the company would wet there brushes with their mouths to create a finer point. After months of this practice, many of the women received cancerous tumors and necrosis of the jaw. As a result, most were buried in lead-lined coffins because of the high emissions of radiation from their bodies. Lead is now used to shield radiation from patients that are not receiving a full body scan. An x-ray is made from a beam of high energy photons passing through the body which are either diminished or blocked entirely when they hit subatomic particles, like bone or metal. The denser and thicker the substance the brighter the image on the radiograph. Both radiological scans, x-rays and CT scans both use ionizing radiation to capture the images of the human body.

Radiology is the branch of medicine that uses radiation to diagnose and treat diseases. Radiologists perform and read multiple modalities such as ultrasound, computed tomography (CT), nuclear medicine, positron emission tomography (PET) and magnetic resonance imaging (MRI). The acquisition of medical imaging is usually carried out by the radiographer or radiologic technologist. Below are a few brief descriptions of each imaging modality: (MITA, 2015) X-Ray- Radiographs are produced by the photons of x-rays passing through a body part to an imaging plate to produce an image. Originally cassettes were used that had crystals imbedded into the film and were processed with chemicals.

X-rays create 2-dimensional images of the body’s bones or internal organs. A beam of X-rays, produced by a generator, is transmitted through the body part to be scanned. The X-rays are absorbed by the material they pass through in differing amounts depending on factors like density and composition of the material. The unabsorbed x-rays pass through the object and are recorded on X-ray sensitive film. X-rays are common procedures, as approximately 7 million are performed every year in Australia. While some may argue there are colossal risks, such as cancer, associated with X-ray imaging, the likelihood of developing cancers is low. For example, an X-ray of your chest, teeth, arms or feet is the equivalent to a few days worth of background radiation and has a less than one in a million chance of causing cancer, according to the UK Health Protection Agency. The increased risk is small, and usually less than the risk from not identifying a disease or condition properly.

X-rays are used for medical purposes. They are a form of radiation named electromagnetic waves (EM Radiation). They are used to take pictures of the insides of the human body which come out in black and white. The X-ray was first developed in 1895 by a man named Wilhelm Conrad Roentgen. While He was working with a cathode-ray tube in his laboratory, Roentgen observed a fluorescent glow of crystals on a nearby table close to his tubes. The tube that he was working with consisted of a bulb with positive and negative electrodes enclosed within it, when the air inside of the tube left and when a high voltage was applied to it , the tube produced a fluorescent glow. Roentgen then shielded the tube with heavy

X-rays and gamma rays are used in medicine to diagnose and treat diseases. X-rays are used mostly for diagnostic testing to produce images of the bones, but they are also used in chemotherapy to treat cancer. Gamma rays can kill living cells, so it is also used in chemotherapy to kill tumor cells. They are also used to kill harmful bacteria and sterilize medical equipment. Gamma rays are used a lot in nuclear medicine to detect abnormalities in the body. (“GCSE Bitesize: X-rays and gamma rays,”

Human body is so complicatedly designed that even a minor issue in an internal organ or organ system can lead to very major consequences for the patient to bear both physically as well as mentally. But with the increase in advancements in science and technology, medical science has reached to extremes for finding out the solutions to every problem faced in the treatment of health problems or any problem faced in the surgeries or operations. When surgeons faced the problems of not being able to see the inside picture of the various parts of the bodies then x-ray techniques were invented out of which chest X-ray is known to be the most important one. Actually a chest X-ray is known to be very fast and painless

If it weren’t for x-rays, how would doctors be able to detect abnormalities within a patient? The x-ray was accidently discovered by physicist Wilhelm Roentgen in 1895. He discovered it when he was experimenting with electric flow currents in a cathode- ray tube and saw a piece of barium platinocyanide giving off light while he was working with the tube. His theory was that when the electrons of the cathode-ray tube hits the wall of the tube an unknown radiation, went across the room and hit the chemical, and then caused a fluorescence.(paraphrase, Encyclopedia Britannica). Also, he thought since he couldn’t find any light refraction or things similar to light, that this new found thing was unrelated to light. He named it X-Radiation, this is also known as Rontgen Radiation. (Fun fact: Roentgen can be spelled without the first e.) Rontgen also experimented further and learned that paper, aluminum, and other metal things were transparent with this new invention. His first x-ray was of his wife’s hand. He looked at the bones in her hand and he looked at the insides of metal objects with his new found machine. Also, Roentgen received a Nobel Prize for his discovery. However, Roentgen wasn’t the only man to discover something in chemistry history.

X-rays are defined as an electromagnetic wave of high energy and very short wavelength. X-rays are able to pass through many materials opaque to light. Visible light is electromagnetic radiation responsible for the sense of sight to humans. Infrared light, microwaves, and radio waves are categories of invisible light that all have the same type of electromagnetic energy.
