X-ray tube

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 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…

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…

X-rays are a very powerful and valuable technique that can provide important and lifesaving information. Fluoroscope, is an x-ray device that allows physicians to view live images inside the human body that are projected onto a viewing monitor during a diagnostic and intraoperative procedures. This machine uses X-rays to give real-time video images on the area of interest making it possible to see internal organs in motion such as blood flow and catheter insertion. A Fluoroscopy captures these…

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…

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…

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…

The X-ray, also called the Röntgen ray, was invented by German scientist Wilhelm Conrad Röntgen in 1985. The x-ray is undisputedly important and is used todays at airports and sporting events to check for weapons and dangerous substances and at hospitals in order to check for fractured or broken bones, internal damage, or items lodged in the digestive system. Despite the x-ray’s numerous and various uses, it’s discovery was unintentional. Wilhelm Röntgen discovered the x-ray while…

Case study of X-ray imaging with grating interferometer on pearls Abstract- With the increase of fraudulent conduct in the field of jewellery there has been increase in the demand for inspection to identify the purity of the product. In this case study X-Ray Radiography is used to identify natural pearls and artificially cultured pearls. In order to understand the internal structure a personalized grating interferometer and inspection has been performed to obtain measurements. The computed…

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…
