摘要
A position sensor used in medical devices for use with medical positioning systems. The position sensor includes a core (80) having a body and one or more projections (841,842) extending from the body, wherein the core comprises a high-permeability material. The position sensor further includes a coil (74) surrounding the body, wherein the coil is configured to generate a voltage when subject to a magnetic field. The one or more projections extending from the body of the core are configured to concentrate the magnetic field into the coil and increase the voltage. Thus, various core designs are described which have projections which may increase the electrical and/or mechanical integrity of the position sensor and/or which may also induce magnetic flux flow within the position sensor thereby increasing the signals generated by the position sensor.
