Metal implant localizers: frontiers and diagnostic feasibility

Abstract

The paper describes and analyses a method for locating metal implants bared on the interaction of a conductive object with a weak alternating magnetic field. Theoretical values for the boundary of detectability and the boundary of localability are introduced to show some technical characteristics, the diagnostic feasibility and limitations of the method. Clinical experiences aye described in order to compare the theoretical expectations with practical results Several advantages of the proposed diagnostic method an terms of inexpensive instrumentation, ease of operation and sensitivity are discussed
