Concerning the original method of magnetic-induction studies of biological objects implementation to determine the future vi-sualization of possible hidden magnetic foreign impurities inside them, based on the general principles of all known methods of non-contact measurement of the magnetic properties of materials and non-invasive study of the body, the following was shown. First a certain model influence of a magnetic field with a known amplitude frequency and spatial parameters (homogeneity), in which a patient is placed in is created. Next according to the change in magnetic flux of the field caused by the presence of a foreign body in a biological object, it is judged about its spatial location in the body, its shape, orientation, and geometric dimensions (length, depth, disclosure). Moreover, if an impurity does not contain the source of the magnetic field, its presence in the model of the magnetic field, only leads to the redistribution of the magnetic flux density (induction). This work is devoted to the development and the physical explanation of biological objects magnetic-induction research information-measuring system realization. The proposed system allows to get images of possible hidden magnetic foreign bodies inside biological objects by measuring the flux density (induction) heterogeneously distributed in the presence of a magnetic field, added by the procedure of initial projection data in the chosen direction differentiation, due to which the reconstructed distribution of the magnetic flux differentiated density by extremes indicates the location of boundary medium borders. The measurements are based on a series of alternating-tilt and swivel angles on the working magneto-measuring body using an algorithm of inverse Radon transformation for the function of an arbitrary number of variables to the projections of the magnetic flux obtained during the parallel formation of initial projection data.
