Abstract: An implantable susceptometry marker (1001) for use in surgical guidance comprising one or more ferromagnetic elements (1004a, 1004b, 1004c); and at least one diamagnetic element (1003); wherein the one or more ferromagnetic elements are formed of at least one ferromagnetic material having an initial relative permeability of at least about 10,000 and a saturation induction Bs of less than about 1.5 T, and the at least one diamagnetic element is formed of at least one diamagnetic material having a bulk susceptibility of at least about −0.16×10−4; and wherein the total volume of diamagnetic material in the marker is about 100-10,000 times greater than the total volume of ferromagnetic material.

Abstract: There is provided an implantable marker for use in surgical guidance. The implantable marker comprises one or more ferromagnetic elements formed of at least one ferromagnetic material and at least one diamagnetic element formed of at least one diamagnetic material. The at least one diamagnetic material comprises graphite having a substantially isotropic grain structure and the one or more ferromagnetic elements are juxtaposed the at least one diamagnetic element.
