| 摘要 |
<p>An elongate medical probe (24), having proximal and distal ends, whose position is tracked within the body of a subject includes a magnetic-field responsive optical element (22) adjacent to the distal end, which modulates light passing therethrough responsive to an externally-applied magnetic field (48). The probe (24) also includes a fiberoptic coupled to receive modulated light from the optical element (22) and convey it to the proximal end of the probe for analysis of the modulation. <IMAGE></p> |
