The Institute of Metal Physics has developed medical flux-gate instruments for location of foreign ferromagnetic bodies (FFBs) by their residual magnetization in human organs. The use of these instruments provides a many-fold increase in the percentage of extracted foreign bodies as compared to traditional methods and considerably decreases the operational traumatism and postoperative complications.

  PF-02 Pole Locator Characteristics: pointer, digital, and sound indication; small dimensions of the working sensors (2.0, 2.5, and 2.8 mm in diameter); highly accurate location of FFBs to within 1.5 mm at a distance of 6 mm. The sensitivity of the PF-02 locator is 20-25% higher than the sensitivity of the Roper-Holl locator, which is its foreign analog. The PF-02 pole locator was tested in clinical conditions aat the Optalmology Department, Ural State Medical Academy. It is used at medical institutions in Moscow (Helmholtz Research Institute of Ophthalmology and Institute for Advanced Training of Physicians) and Ekaterinburg (Regional Clinical Hospital No. 1, Municipal Hospital No. 23, and the Regional Ophthalmological Center).
