发明名称 Apparatus for detecting surgical objects within the human body
摘要 An apparatus and method detects surgical objects within the human body where the apparatus includes the surgical object utilized in surgical procedures including a marker made of a selected nonmagnetostrictive, soft magnetic material which will emit known specific selected 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.
