X-ray

X-rays Science Assessment 9B History 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

X-rays is one of the many discoveries that revolutionized the way the humanity functions technologically, economically and socially in a fast changing world. This invention was thanks to Dr. Rontgen. His invention changed the medical and astronomy field drastically and therefore he was awarded the first Nobel prize in physics. He was awarded this incredible and highly valued award in the year 1901 after producing, detecting and then discovering these high frequency wavelengths produced by electromagnetic

X-ray probe production by a synchrotron light source. To optimize the properties of nano-material and atomic level needs an elemental probe with resolution of <1nm. The nano scale probe helpful to provide the reproducible control over defects. The production of x-rays by relativistic electrons in accelerators is about 60 years old. The accelerator facilities used as synchrotron radiation sources have advanced significantly over the years, growing in utility to become a premier research tool for

The science behind the x-ray goes back to a chemist called Sir William Crooks. He was born June 17th 1832 in England. Crooks developed the Crooks Tube in 1870. This was an important invention for scientists to come, among them was Wilhelm Roentgen who in 1895 was credited with the discovery the x-ray. Back when the x-ray technique was new, people didn’t realize the damage radiation could cause. This changed soon when it was discovered how people were severely injured from the exposure, as they were

Polarization of X-rays was first demonstrated by Barkla. He was performing experiments on the secondary X-ray radiation phenomena (C. G. Barkla 1905). He used a block of graphite that scatters the primary X-ray beam from an X-ray tube. The scattered intensity of the X-ray beam was measured in two mutually perpendicular directions. He denoted the scattered intensity in a parallel direction to the tube axis I_pand the one scattered at right angles I_s. The degree of polarization for X-rays emitted at an

X-rays have come a long way since 1896; new technology, materials and even machines have changed the concept of a typical x-ray image since the discovery. New imaging techniques described in Origin and Development of Medical Imaging apply in computerization to conventional X-rays images. These images have incredibly improved and can be enhanced by digital techniques and the extremely great effect of these x-rays is the reduction of exposure to radiation to the patient (Doby, Alker 118).

X rays and Ultrasound are two of the main imaging techniques used in radiography. For the purposes of this essay, we will look at conventional x-rays and diagnostic ultrasound. Conventional x rays are non-invasive diagnostic techniques that are used to capture images of the body's organs and bones. Diagnostic ultrasounds are high frequency sound waves to create an image of soft issues in the body such as muscles, joints, and internal organs. As examined below, while both are used in diagnostic radiography

radiology at Glasgow, created the first x-ray of a kidney stone, an image showing a penny in the throat of a child, as well as an image of a frog’s legs in motion. An American physiologist experimented with x-rays in order to trace food as it traveled through the digestive system (Waters, 2011). In 1896, Dr. Hall-Edwards became one of the first physicians to use x-rays to diagnose a patient, when an x-ray revealed that a needle was embedded in the patient’s hand. X-rays quickly became a vital tool used

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 hand, but just his bones. Roentgen covered the tube with heavy black paper and saw that the crystals still glowed and the shadow of his hand bones still shown through, he then determined that a new ray was being emitted that could penetrate through thick materials. (1.) He later found that the rays could pass through

In my 30-plus years in the X-ray profession, I have performed thousands of X-ray examinations. The technology and its contribution to patient care still fascinate me. X-rays — or radiography, as it is known in medicine — allow for looking inside a body and identifying everything from broken bones to swallowed objects. The tool is vital to the ability to diagnose and treat injuries. Radiologic technology encompasses a wide spectrum of specialties, from radiographers (who produce 3-D and 2-D images
