Mode of action. The length of X-ray wave is less than the length of the visible light wave, and it can penetrate the body tissues. During the ray transmission, dense tissues, like bones, absorb the rays, therefore a light silhouette remains on the film or X-ray diagram. Soft tissues are imaged as darker areas. X-ray is usually applied for diagnostics of dental, bone, mammary and chest diseases. To make it possible for a doctor to differentiate soft tissues of the same density, the contrast agent is injected in the patient’s blood in some cases. Nowadays, X-ray image is often transferred to the computer display.

X-ray radiography. X-ray method of examination is an important and valuable method, as it ensures prompt identification of availability of a pathological process and its character. Moreover, it allows for examination of the moving organs, which is very important for X-ray diagnostics.

Advantage of this method is that high resolution of X-ray films makes it possible to obtain highly-detailed images, which can facilitate precise determination of the pathological process activity and reaction of the adjacent tissues. Another important aspect of this method is the lesser irradiation burden owing to shorter exposure of both the doctor and the patient. With the X-ray method of investigation, an X-ray image is obtained which reflects objectively the X-ray structural changes in the investigated organ and serves as a document at the same time. It is highly important. Through comparison of the repeated images, progression of the pathological process may be studied.
