Title:
インピーダンス・シフトおよびドリフトの検出および補正
Document Type and Number:
Japanese Patent JP6656271
Kind Code:
B2
Abstract:
An impedance location of an electrode in an impedance based coordinate system and a magnetic location of a magnetic position sensor in a magnetic based coordinate system can be received. A transformed impedance location of the magnetic position sensor can be computed. A difference between the transformed impedance location of the magnetic position sensor and the magnetic location of the magnetic position sensor can be determined. A magnitude of the difference between the impedance location of the magnetic position sensor and the magnetic location of the magnetic position sensor can be computed. A statistical significance of the difference between the transformed impedance location of the magnetic position sensor and the magnetic location of the magnetic position sensor can be computed. A determination can be made that an impedance shift exists if the magnitude of the difference exceeds a threshold and a statistical significance of the difference exceeds a threshold.
