ABSTRACT:
Provided is an electromagnetic coil arrangement comprising a set of electromagnetic sensors at fixed locations with respect to each other, each of the electromagnetic sensors comprising a planar coil coupled to a conductive layer, the planar coil comprising non-concentric rings. Further, provided is an electromagnetic tracking system, comprising an electromagnetic coil arrangement, at least one complementary electromagnetic sensor and a processor configured to process a signal comprising data indicative of a mutual inductance between the at least one complementary electromagnetic sensor and each of the set of the electromagnetic sensors of the electromagnetic coil arrangement. Also, provided are a method of tracking and a method of manufacturing an electromagnetic coil arrangement.
