FIELD: medicine.
SUBSTANCE: device comprises means for selecting and focusing to form a magnetic field for selection and focusing having at least one set of selection and focusing coils, at least one inner coil formed as a closed loop around its axis, a group of at least two outer coils, located at a greater distance from the inner coil axis, wherein each of the coils is formed as a closed loop around the respective outer coil axis, and an exciter comprising an excitation field signal generator unit and coils for changing the spatial position and size of the two sub-zones in the visible region using the excitation magnetic field so that magnetic material magnetization changed locally.
EFFECT: use of the invention allows to perform adults survey.
