X-ray Essays

Diagnostic imaging techniques such as MRI and X-ray scans are both use in medical/clinical settings to help doctors with their diagnosis of a patient 's body. By using these techniques, a more accurate diagnosis of a potential or present injury/ illness of a person can be understood and can be visually determined. With that being said one major difference in the way that the two techniques obtain their images is the use of radiation. In an X-ray scan the use of gamma radiation helps with being

tomography, uses X-Rays from many different angels to make a detailed picture of the structures inside the body. It allows doctors to see what is happening inside the body without having to cut somebody open. A CT scan is taken in a donut shaped ring and a bed, the bed gets rolled into the scanner. An MRI, standing for magnetic resonance imagining, use strong magnetic fields to make photos of the organs in a person's body without cutting the body open. An MRI machine does not use X-rays to make photos

Radiology would not be complete without mentioning rays. It's our ability to harness these Ray's and translate them into images that makes the field of radiology viable. X Ray machines in particular are used in identifying, diagnosing and treating a vast array of diseases. The mechanism for X-rays differ, but they all have the same principle. The person credited for discovering X-rays is the German physicist Wilhelm Roentgen who discovered it by accident. While messing around with an electron beams

Radiographers should always apply the As Low As Reasonably Achievable or ALARA principle when undertaking a medical X-ray exposure. There are evidences that demonstrate that diagnostic X-ray procedures have the ability to induce cancer and genetic effects, although the risk is known to be very low. Hence, it is the responsibility of radiographers to always ensure to minimise this risk by minimising the radiation dose to the patient, ultimately producing the best diagnostic image and delivering the

n this essay I will be talking about X-rays.I will also talk about how pneumonia is able to be treated by X-rays. X-rays are a kind of radiation called electromagnetic waves. X-ray imaging forms images of the inside of a human body. The picture will show the part of your body in various shades of black and white. This is a result of various tissues taking in various amounts of radiation. Calcium in bones take in X-rays the most, so bones look white. Fat and other soft tissues take in less, and look

was first discovered in the early 19th century. William Herschel discovered infrared radiation, and Johann Wilhelm Ritter discovered ultraviolet. Heinrich Hertz first produced radio waves based on Maxwell’s theories, and Wilhelm Röntgen discovered X-rays. In present time, electromagnetic radiation is important. It is commonly used in telecommunications, household appliances and also medical equipment. Even though electromagnetic radiation has its risks, technology is

diseases seen within the body. Radiologists use many imaging techniques including: X-ray radiography, ultrasound, computed tomography, nuclear medicine including positron emission tomography, and magnetic resonance imaging to diagnose and treat diseases." Some of the experiments they do include testing X-ray dark-field radiography on a living organism for the first time. They test the organism for lung disease. X-Ray dark-field radiography produces very detailed imagines of the lung. They hope to be

professionals to look inside a person’s body through the development of detailed pictures or scans. Computed Tomography (CT) technology is one such modality that takes detailed cross-sectional images using computer controlled X-ray technology (Davis, 2016). Other modalities include standard X-ray and Magnetic Resonance Imaging both of which can also create pictures of inside the body. Since these modalities all serve similar functions, why would doctors need to choose from more than one method to diagnose

The inventor of radiology was scientist, Wilhelm Conrad Roentgen, and the first ever x-ray was actually of his wife's left hand on December 22, 1895. This machinery took off and is used all over the world by a Radiologic Technologist. A Radiologic technologist performs all types of medical imaging procedures, but most commonly x-rays. Radiologic technologists are also known as radiographers or x-ray techs. They provide a high standard of patient care, prepare patients for examinations, and explain

A century ago, X-rays were introduced and provided noninvasive ways to view structures in the body, such as bones. X-rays cannot view the soft tissues within the body except with contrast-enhancing agents that are injected or swallowed, even still image resolution is limited. Current x-rays systems are very hard to create and use large amounts of energy. Researchers at Massachusetts Institute of Technology (MIT) and Massachusetts General Hospital (MGH) have a new approach which could dramatically

will have an X-ray, ultrasound, MRI, or one of any of the many other imaging techniques at some point. The use and development of various radiologic techniques have reduced the need of exploratory surgeries and given us a better idea of what is going on inside our bodies. Radiology as we know it today was was invented over a century ago by a German physicist and Professor named Wilhelm Conrad Roentgen 1. In 1895 he discovered electromagnetic radiation in in a wavelength range, or the X-Ray. When Roentgen

Photoelectric interaction is one of the main interactions in producing x-rays. This occurs when an inner shell electron is knocked out leaving a hole that needs to be filled. It will be filled by an outer shell electron which will be filled by an auger electron eventually. Photoelectric interaction doesn’t have as much scatter compared to the other interactions. This is due to the photons being almost completely absorbed by the patient as the photons pass through the body to hit the image receptor

There are different types of image modalities in healthcare such as a CAT Scan, MRI, X-Ray and ultrasound imaging modalities. A CAT Scan is an X-ray image made using computerized axial tomography. Magnetic resonance imaging, more known as MRI is a medical imaging technique that is used in radiology to form pictures of the anatomy and the physiological processes of the body in both health and disease. An X-Ray is a photographic or digital image of the internal parts of something, especially a part

conduct more advanced procedures and experiments on patients. Although the first x-ray was invented in 1895, the first ever department of radiology was opened in July of 1954. Since it was first created, sonography has made a huge impact on patients, especially women. Ultrasound scans have come a long way in the world of radiology, along with CT scans, MRI scans, and x-rays. Today, the field of radiology includes x-rays, CT scans, MRI scans, and ultrasounds. The continuation of advancing technology

achieved, assessment of image quality must be made to balance against patient dose. X-rays are known to cause malignancies, skin damage and other side effects and therefore are potentially dangerous. It is therefore essential and mandatory to reduce the radiation dose to patients in diagnostic radiology to the barest minimum (Watkinson, Moore’s., 1984). Radiographers are technologist who create and analyze the x-ray image. Diagnostic radiography plays an important part in the treatment of neonates

Layer The half value layer (HVL) is the thickness of a shielding material required to reduce the intensity of radiation at a point to one half of its original intensity. It can be calculated by setting I = ½ I_0 and solving the attenuation equation for x: 0.5=e^(-μx_(1⁄2) ) x_(1⁄2)=-(ln⁡(0.5))/μ

Ultrasound can be used as an alternative to x-ray for many investigations to minimize the use of radiation. The utility of ultrasound in the NICU lies in its portability, reliability and lack of radiation exposure. In NICU, ultrasound can be used for a wide range of indications, such as research, proceed guidance and rapid assessment of critical emergencies. In addition, ultrasound can be a guidance to improve safety and success rate of clinical procedures, such as umbilical vein catheter (UVC)

annoying and aggressive procedures such as myelography (lumbar puncture), arthrography (introduction of contrast media in joints) and others involving aggression or discomfort to the patient. Magnetic resonance imaging is a diagnostic study in which no X-ray magnetic waves are used but this type of

or “x-rays”, of the patient. One main type of a dental radiographic image would be a panoramic radiograph. Panoramic X-rays show a wide screen view of the teeth, temporomandibular (jaw) joints, sinuses, and the nasal area. These radiographic pictures show

In the 1980s there were 12 MRI machines in the world and the men and women who used them knew each other. Now there are over 25,000 MR systems worldwide and operated by thousands. However, in Europe there are on average 11 Magnetic Resonance systems per 1 million people, while only 0.5 systems per million people in India which are densely distributed around wealthier cities, leaving poorer areas lacking in medical imaging facilities.
