International day of Radiology

Tuesday - November 8, 2016 9:31 am , Category : WTN SPECIAL

Radiology is a science of study to find out the diseases within the body by using imaging. A variety of imaging techniques are used for the same such as computed tomography (CT), positron emission tomography (PET), magnetic resonance imaging (MRI), ultrasound, X-ray radiography. These imaging methods are carried by radiologist specialized for conduction of such imaging and study. Radiology is self elaborated branch of medical science and need long and thorough and certified degree to undertake as profession.
The history of Radiology is as old as the medical science evolution and has brought revolution in cure and treatment of deceases which were hidden in body and were difficult or yes we can say impossible to diagnose and follow its cure.

November 8 is the International Day of Radiology and this year the day is dedicated to breast imaging and the essential role that radiology plays in the detection, diagnosis and management of diseases of the breast. Today world is celebrating international day for Radiology and WTN brings you on this very day the journey of Radiology in picture.

Radiographs (originally called roentgenographs, named after the discoverer of X-rays, Wilhelm Conrad Röntgen). Röntgen discovered X-rays on November 8, 1895 and received the first Nobel Prize in Physics for their discovery in 1901.

Röntgen discovered X-rays’ medical use when he made a picture of his wife’s hand on a photographic plate formed due to X-rays. The photograph of his wife’s hand was the very first photograph of a human body part taken using X-rays. When she saw the picture, her comment was, “I have seen my death.”

By the time the hazards of X-rays were know it was too late and diagnostic use of x-rays were already started before the dangers of ionizing radiation were discovered and as an enlightenment, it was Madam Marie Curie who pushed for radiography to be used to treat wounded soldiers in World War I.

However the use of x- rays were never limited to medical science but its use in science is far away indefinite imagination and significance and for development of mankind.

· X-ray crystallography in which the pattern produced by the diffraction of X-rays through the closely spaced lattice of atoms in a crystal is recorded and then analysed to reveal the nature of that lattice. A related technique, fiber diffraction, was used by Rosalind Franklin to discover the double helical structure of DNA.

· X-ray astronomy, which is an observational branch of astronomy, which deals with the study of X-ray emission from celestial objects.

· X-ray microscopic analysis, which uses electromagnetic radiation in the soft X-ray band to produce images of very small objects.

· X-ray fluorescence, a technique in which X-rays are generated within a specimen and detected. The outgoing energy of the X-ray can be used to identify the composition of the sample.

· Industrial radiography uses X-rays for inspection of industrial parts, particularly welds. Using X-ray for inspection and quality control: the differences in the structures of the die and bond wires reveal the left chip to be counterfeit.

· Authentication and quality control, X-ray is used for authentication and quality control of packaged items.

· Industrial CT (computed tomography) is a process which uses X-ray equipment to produce three-dimensional representations of components both externally and internally. This is accomplished through computer processing of projection images of the scanned object in many directions.

· Paintings are often X-rayed to reveal underdrawings and pentimenti, alterations in the course of painting or by later restorers. Many pigments such as lead white show well in radiographs.

· X-ray spectromicroscopy has been used to analyse the reactions of pigments in paintings. For example, in analysing colour degradation in the paintings of van Gogh

· Airport security luggage scanners use X-rays for inspecting the interior of luggage for security threats before loading on aircraft.

· Border control truck scanners use X-rays for inspecting the interior of trucks.

· X-ray art and fine art photography, artistic use of X-rays, for example the works by Stane Jagodič

· X-ray hair removal, a method popular in the 1920s but now banned by the FDA.

· Shoe-fitting fluoroscopes were popularized in the 1920s, banned in the US in the 1960s, banned in the UK in the 1970s, and even later in continental Europe.

· Roentgen stereophotogrammetry is used to track movement of bones based on the implantation of markers

· X-ray photoelectron spectroscopy is a chemical analysis technique relying on the photoelectric effect, usually employed in surface science.

Fluoroscope exams gave much higher radiation exposures than film x-ray images. This image was used to demonstrate the myth about exposure to radiation during the x-ray procedure.

$Each dot, called a reflection, in this diffraction pattern forms from the constructive interference of scattered X-rays passing through a crystal. The data can be used to determine the crystalline structure.$

Chandra’s image of the galaxy cluster Abell 2125 reveals a complex of several massive multimillion-degree-Celsius gas clouds in the process of merging.

TEAPOT – The Boeing B-47 Stratojet, Strategic Air Command’s primary medium bomber, is among the aircraft participating in the current nuclear test series at the Nevada Test Site. Powered by six turbojet engines, this swept wing bomber can fly higher and faster than any bomber in its class. Twenty-nine of these aircraft will be used on various Teapot shots. Most of them are reconnaissance types which are being employed on photographic missions.
