POSITION DETECTION DEVICE AND MEDICAL DEVICE POSITION DETECTION SYSTEM |
摘要 |
A position detection apparatus and a medical-device-position detection system that have improved position detection accuracy are provided by setting high amplification for the position detection apparatus. The position detection apparatus includes a circuit that has at least one embedded coil (10a) and that is provided inside an object (10) to be detected; a first magnetic-field generating unit (11) for generating a first magnetic field in the region where the embedded coil (10a) is disposed; a magnetic-field detecting unit (5, 12) for detecting an induced magnetic field generated at the embedded coil (10a) by the first magnetic field; and a second magnetic-field generating unit(23) for generating a second magnetic field having a phase substantially opposite to the phase of the first magnetic field. |
