  • Method and system for characterizing and visualizing electromagnetic tracking errors
    Patent number: 9165114
    Abstract: A calibration/surgical tool includes an electromagnetic sensor array of two or more electromagnetic sensors in a known geometrical configuration. Electromagnetic tracking errors are characterized by a mapping of pre-operative absolute and relative errors based on a movement of a calibrated calibration/surgical tool through a pre-operative electromagnetic field. Using statistical mapping, a desired absolute error field is measured either in the clinic as the part of daily quality control checks, or before the patient comes in or in vivo. A resulting error field may be displayed to the physician to provide clear visual feedback about measurement confidence or reliability of localization estimates of the absolute errors in electromagnetic tracking.

  • METHOD AND SYSTEM FOR CHARACTERIZING AND VISUALIZING ELECTROMAGNETIC TRACKING ERRORS
    Publication number: 20120323111
    Abstract: A calibration/surgical tool (90, 160) includes an electromagnetic sensor array (30) of two or more electromagnetic sensors in a known geometrical configuration. Electromagnetic tracking errors are characterized by a mapping of pre-operative absolute and relative errors based on a movement of a calibrated calibration/surgical tool (90, 160) through a pre-operative electromagnetic field. Using statistical mapping, a desired absolute error field (46) is measured either in the clinic as the part of daily quality control checks, or before the patient comes in or in vivo. A resulting error field (46) may be displayed to the physician to provide clear visual feedback about measurement confidence or reliability of localization estimates of the absolute errors in electromagnetic tracking.
