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 transformedimpedance 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.

Description

[0001] Cross References to Related Applications [0002] This application is related to an application entitled "IMPEDANCE SHIFT AND DRIFT DETECTION AND CORRECTION," filed June 20, 2016, having document number CD-1054US02 (065513-001425). This application claims priority to U.S. Provisional Patent Application no. 62 / 182,208, filed June 19, 2015, entitled "IMPEDANCE SHIFT AND DRIFT DETECTION AND CORRECTION," the entire contents of which are hereby incorporated by reference as if herein Exactly the same. technical field [0003] The present disclosure generally relates to impedance displacement and offset detection and correction. Background technique [0004] The three-dimensional coordinates of a catheter or other medical device moving within a patient's body are typically tracked using a positioning system (also sometimes referred to as a "mapping system," "navigation system," or "position feedback system"). These devices typically use magnetic, electrical, ultrasonic, a...
