Electroradiography

Electroradiography (ER) is a radiography method in which the image of an object is recorded using an electron-optical converter. The ER image is recorded on a photosensitive material or on a digital storage medium.

The method is based on the conversion of X-rays into visible light using an electron beam device. The method was proposed in 1933, but only came into practical use after the invention of semiconductor converters in the 1960s.

An ER image is obtained without the use of photographic materials and chemical reagents, which significantly reduces the time of image acquisition and simplifies its processing. In addition, ER images have higher contrast and better detail than traditional X-rays.

The ER method is widely used in medicine to diagnose diseases of teeth, bones, joints and soft tissues. ER is also used in industry for product quality control, in archeology for the study of ancient artifacts, and in other areas where fast and accurate image acquisition is required.

Electroradiography or electrography is a medical research method based on shining an X-ray beam through the body through the tissue structure. In this way, both the patient and pathological neoplasms are examined. X-ray electrography differs from conventional electrography in that it enhances the effect of X-ray radiation.

Electro-X-ray helps to improve the quality of the resulting image due to the unique interpretation of images that most accurately reproduce the intensity of images of organs. The method is used for the diagnosis and treatment of pulmonary diseases, heart defects, tumors of various types, and blood vessels.

The radiation technique was obtained thanks to the work of the Russian physicist I.K. Kirilov and abroad as a result of research by J.-R. Erisa. A few years after this, the method was presented at a world conference in France. But this diagnostic technology received active development in the post-war years. Already by 1956, electrographics reached 90% diagnostic accuracy in detecting tuberculosis. The method actively contributed to the early diagnosis of cancer in people and worked to improve radiation medicine technologies.
