[Localizing foreign ferromagnetic bodies by means of the PF-02 ferroprobe polarity detector].

The paper analyzes the problems, facilities and techniques for enhancing the accuracy of localization of a foreign ferromagnetic body. To tackle this problem is associated with further improvement of the parameters and characteristics of an electronic polarity detector unit, by using a new element base. In this connection, a PF-02 polarity detector model with its new construction of a ferroprobe transducer is presented. The device defines the inhomogeneity of static magnetic field acting on the ferroprobe transducer at the gradient range of 0.00024 A/cm2 to 1.2 A/cm2. The clinical testing of the device enables polarity detector to be more effectively used in medicine.
