[Use of electrical impedance tomography in detection of latent diseases during mass screening].

The paper deals with the use of the present-day highly effective method of introscopy electric impedance tomography (EIT) for diagnosis latent abnormalities during mass screening. EIT images viscera and tissues on the basis of their electric conductivity differences. Reconstruction of the images reflecting the distribution of electric conductivity values in the body is made from the recording potentials onto the body's surface while passing currents through the electrodes located along the circumference of the body's part under study. The 16-electrode EIT system developed by Dipol (Moscow) was used to examine the distribution of electric conductivity values in the extremities and chest organs in healthy volunteers of both sexes and in patients with various pulmonary diseases.
