A branch of medicine that deals with the diagnosis of diseases in the internal organs of the body by taking advantage of X-rays and other ionizing radiation methods such as x-ray and gamma, as well as the treatment of these diseases. Radiology is handled in two main sections.
The X-ray beams were found by Wilhelm Conrad Röntgen in 1895 (see Röntgen Rays). After 20 years of finding X-rays or X-rays, there are many different methods in practice. E.g;
In 1912, a chimography technique (examination of the movement of internal organs), a pyelography or urography technique (filminin extraction of urinary tracts) in 1930, radioisotopes in 1939, and betatron and radioactive cobalt in 1947. During the exercise, the x-rays are divided into soft and hard. The frequency of soft x-rays is low,
the wavelength is long. Hard x-rays have short wavelength and high frequency. The excess of hardness is the greatest feature of x-rays and is directly proportional to the ability to enter objects.
x rays can pass very easily through thicker materials with less atomic weight.
The most calcium in the body, at least air, absorbs x rays. Blood, muscle and fat texture are located between these two. The bones with a high amount of calcium that they have sprouted appear clear to the very finest detail in the film. For example, cracks in the bones are easily detected in the x-ray film. Any abnormality in the lungs, the lesion (eg an abscess) is easily detected as a black-and-white image due to the air inside.
For the extraction of x-ray films, the x-ray beam, which is mounted in specially prepared chambers, is used for the capture of x-ray films. /> devices are required. The table on which the patient is to be placed may vary according to the filmin cinnamon to be withdrawn. Detection of X-rays is a normal picture taking. The silver compound melt, which is spread on acetate cellulose, is sensitive to x-rays.
X-rays are reflected in the thick bony parts of the body, causing undesirable shadows in the film.
Sieve plates made from lead strips that swallow reflected rays are used to prevent these shadows. These sieves are located between the x-ray tube and the body. In order to obtain a three-dimensional image of the body such as the head and the hips, the x-ray tube is fixed in two positions. To do this, the x-ray machine must have a tereoscopic film-drawing system.
The film will leave traces in the film according to x-rays and densities of different tissues. The organs that leave little traces are concentrated externally by giving special
materials. For example, barium sulfate solution to bring the matter into visible state; a solution of barium sulphate mixed with resin for thick intestine film; iodinated organic compounds for film of capillary regions with circulatory system; iodinated vegetable oil or ethyl idodophenyl undecylate solution is used for the spinal cord and bronchial film. Such substances are given the name of a radiopaque substance.
The methods of X-ray detection made with these substances take different names according to the field to which they are applied.
X-ray films are very important in the diagnosis of many diseases. Even in some cases, it is possible to definitively diagnose with X-ray films. Fractures, dislocations, lung abscess, mydial puncture,
intestinal obstruction are just a few of them. Due to the importance of diagnosis and treatment of x-ray films and techniques, radiology has become a specialty.
A common application of x-rays is also a radioscope. This technique, also known as “mirror” between the people, Any organ of a person between a source of x-rays and a fluorescent screen is being examined directly on the current screen (by fluoroscopy or by radioscopy). Shared Information Multiply.
