ABSTRACT:
A method and apparatus for detecting, distinguishing and counting marked objects and particularly marked surgical objects having a marker made of a selected nonmagnetostrictive, soft magnetic material which will emit known specific selected high harmonic frequencies when exposed to an alternating electromagnetic field. That emission will cause a change in the alternating electromagnetic field which can be correlated to the presence of only the selected nonmagnetostrictive, soft magnetic material.
