X-ray technician

. Discovered there is however more than 100 years, radiography keeps an undeniable diagnostic interest in much of fields of medicine. Radiography is a diagnostic examination which uses x-rays However, contrary to the photograph, radiography does not give an image of our body envelope. As x-rays cross the matter, the radiographic film can keep the impression and deliver the image of our internal anatomy. According to the radiographed body, the stereotype will be more or less blackened. Thus, on a radio, the osseous structures, which absorb the radiation, will appear in white and of the bodies such as the lungs, in black. Known for their property of penetration of the matter, x-rays will be it also quickly for their harmfulness. The uses of this examination are multiple. Thoracic radiography is one of the examinations most frequently prescribed. Radiography is not therefore the universal panacea. It does not show all and what it reveals is sometimes not very significant. It remains nevertheless a means simple to seek the elements which will allow, after being refined by complementary examinations, to pose a diagnosis.

Radiography is a fast and painless examination which does not require any preliminary preparation. You will go in a room where is installed an apparatus of radiography, composed of a hinged jib provided with a tube with x-rays and a plate containing film. You will be able to see behind a leaded pane, protective of the toxic rays, the control panel behind which the doctor or the technician will place themselves. To carry out a stereotype of the thorax, the doctor or the technician will place you upright, naked chest, low shoulders and elbows ahead, counters the support which contains radiographic film. It will ask you to take a deep inspiration, to make the lungs more visible, then to block your breathing... and not to move more. This radio of face will be then supplemented by a stereotype of profile. A radiography gives an image in two dimensions of various fabrics and bodies. Therefore, on the stereotype, those are superimposed. It is sometimes difficult to know what hides in front of or behind the elements of our body most visible with the image, like the osseous structures. In this case, a radio of profile can bring a further information interesting. To reduce the problem of the superposition of fabrics and the bones, the technician will ask you to take precise positions. Several radios will be produced, here also, generally, of face and profile. Very often, at the end of the examination, the radiologist will make you a first comment on the stereotypes carried out. Its final report will be addressed to the doctor prescriber of the examination, your general practitioner or the specialist, which will explain you the results. Precautions against the rays radiography uses dangerous rays for the organization. Admittedly, the quantity of x-rays emitted at the time of radiography is tiny: it is considered that a simple stereotype corresponds so that your body receives if it is subjected to the natural exposure of the sun at the time of a voyage by 4 hour old plane each new stereotype, your body will absorb an additional amount of rays. To multiply the radios can be dangerous. Therefore, children, adults, not of useless stereotypes. The radiographic examination is not pain-killer. Besides it presents counter-indications for the pregnant woman at the beginning of pregnancy. If you await a happy event, warn always the radiologist.
