Patent ID: 8483795

Claim:
An apparatus for detecting and measuring the magnetic field produced by a primary electric current source within a conductive biologic structure, the apparatus comprising: a conductive medium configured to immerse the biologic structure, the conductive medium being selected from a group consisting of a conductive liquid and a conductive gel, the conductive medium having a first surface; a non-conductive solid object fully immersed within the conductive medium, wherein the non-conductive solid object is positioned between the primary electric current source and the first surface, the non-conductive solid object having a surface which is neither parallel nor perpendicular to the first surface of the conductive medium, wherein there is no electrical connection to the non-conductive solid object, and wherein the non-conductive solid object is configured to produce a secondary source responsive to the primary electric current source; and a means for detecting and measuring magnetic fields, wherein the detecting and measuring means is located external to the conductive medium.
