POSITION DETECTING DEVICE, MEDICAL DEVICE GUIDING SYSTEM, POSITION DETECTING METHOD, AND MEDICAL DEVICE GUIDING METHOD |
摘要 |
Provided is a position detecting device including a first magnetic-field generating unit including at least one magnetic-field generating coil and that generates a first magnetic field in a detection space where a detected object provided with a circuit including at least one built-in coil is disposed; a magnetic-field detecting unit having a plurality of detecting coils arrayed to detect an induced magnetic field generated from the built-in coil by the generated first magnetic field; and a second magnetic-field generating unit including at least one magnetic-field generating coil, that generates a second magnetic field, and including a magnetic-field component having a phase substantially opposite to the first magnetic field and entering the detecting coils, wherein the first magnetic-field generating unit and the detecting coils are disposed so that a generating direction of the first magnetic field and a detecting direction of the induced magnetic field intersect each other.
