  • Importance Of CT Scanner

    Depends upon several steps:- 1-The x-ray tube and detector transverse (scan) the object. 2-The radiation beam passes through the object and is attenuated. The intensity of radiation beam from x- ray tube and transmitted beam both are detected by suitable detectors. 3-The transmitted beam and the references beam are both converted into electric signals. 4-These output current signals are then converted into digital form by analog –to-digital converter. 5-The digital data are then normalized and the logarithms calculated to generate relative transmission values : Relative transmission values =log I0/I. 6-The relative transmission values are sent to the computer, which uses suitable programs to reconstruct cross sections…

  • X Rays Research Paper

    X-rays is one type of electromagnetic radiation that can send waves through the body which makes us see through the body tissue but it doesn’t go through the bone. Therefore it is used in hospitals to see if a person has a broken bone or any diseases. Because it can go through clothes and the human skin it is also used in airports to see if anybody has a knife or anything dangerous with them. X-rays were first discovered by German scientist Wilhelm Conrad Roentgen in 1985. Roentgen found x-rays…

  • X Rays History

    In 1895, x-rays were discovered by Wilhelm Conrad Roentgen. He was a Professor at Wuerzburg University which was in Germany. He worked with a cathode-ray tube in which he observed a fluorescent glow of crystals on a table near the tube. The tube that Roentgen was working with at the time was made of a glass envelope with positive and negative electrodes filled in it. The air that was in the tube was let out. When a high voltage was applied, the tube produced a glow that was fluorescent. He then…

  • Radiation Protection Research Paper

    X-rays were discovered in 1895 by Wilhelm Conrad Roentgen, a Professor at Wuerzburg University in Germany. While working with a cathode-ray tube in his laboratory, Roentgen observed a fluorescent glow of crystals on a table near his tube. In the past, people were unaware of how harmful x-rays are, because they are invisible. Scientists and researchers working in the radiography field were not aware of the effect on the body after continuous exposure. When radiography was in its infancy, it was…

  • Essay On Radiography

    process of producing x-ray pictures, also known as RADIOGRAPHS. X-rays were discovered on November 8, 1895 by Wilhelm Conrad Roentgen in Germany at the University of Wurzburg. Radiographs are produced through the use of radiation. There are three different types of radiation. These include PRIMARY RADIATION, REMNANT RADIATION, and SCATTER RADIATION. Primary is the radiation that leaves the tube, remnant is the “exit radiation” that passes through the image receptor, and scatter has less energy…

  • Informative Essay On Photography

    lab with a cathode-ray tube when he saw a fluorescent light coming from crystals on a table near his cathode-ray tube. The tube Roentgen was using had a glass bulb with positive and negative electrodes condensed inside it. During his experiment trial, he first released the air in the tube. Then, he increased the voltage inside the tube, resulting in a neon indigo light appearing from the cathode-ray tube. Afterwards, Roentgen covered the tube with a dense black barrier, and noticed a fluorescent…

  • How Did Radiation Change

    over the years and wasn’t even known to be used in medicine until after it was used in the military in World War II. It was discovered by a German scientist but then the possibilities of all the things it could be used for was discovered by a Polish-born French scientist. Radiation changed medicine for the better by killing off cancerous, disease ridden germs and cells, this is significant because it changed the way we look at treatment. In 1895, radiation had just been discovered by Wilhelm…

  • Computed Tomography

    passage of x-ray beams through the region of interest. The multislice CT (MSCT) means CT that the system equipped with multiple rows of CT detectors to create images of multiple sections. The data obtained from the patient will be transformed into “cuts” or cross-sectional slices of the human body (Romans, 2011). In early 1970, they use a single slice CT scan that contributes too many disadvantages such as take a longer time to get a slice of images. Over the years, the CT scan technologies have…

  • Interventional Radiology Essay

    1.0 INTRODUCTION It is known that radiation can be very harmful to a person’s health. According to Marshall and Keene (2006:1), with the recent expansion of diagnostic and interventional radiology, it has been noted that an alarming dose of radiation can be administered to a patient, in a single scan, without having to repeat a procedure. With the evolution of radiography, interventional radiology has become a norm in the diagnosis protocol and it is therefore important to understand the concept…
