The article is devoted to the methods of imaging of the internal structure of conductive objects such as biological tissues and organs based on the use of interaction with the objects of radio frequency electromagnetic fields with wavelengths much greater than the size of the object. Three methods of the quasistatic electromagnetic tomography are analysed: electrical impedance, magnetic induction and electric field tomography. Theoretical foundations of the methods and approaches to their practical implementation including experimental systems for creation and measuring of the probing electromagnetic fields, as well as algorithms for solving inverse problems providing effective reconstruction of spatial distribution of electrical properties of biological media and their visualization, are described. Current achievements and trends in the development of researches in this area are outlined.
