Title:
位置および配向の磁気測定
Document Type and Number:
Japanese Patent JP5333832
Kind Code:
B2
Abstract:
A magnetic position and orientation determining system uses magnetic fields, desirably comprising uniform fields from Helmholtz coils (34, 36, 38) positioned on opposite sides of a sensing volume and gradient fields generated by the same coils. By monitoring field components detected at the probes (50) during application of these fields, the position and orientation of the probe (50) in the field can be deduced. A representation (108) of the probe (50) can be superposed on a separately acquired image of the subject to show the position and orientation of the probe (50) with respect to the subject.
