METHOD AND APPARATUS FOR POSITION OPTIMIZATION OF A FIELD GENERATOR

摘要

An electro-magnetic tracking system (50,110) includes a system controller (58) having a sensor interface, a generator (52), and a positioning and angular orientation configuration (62,114). The generator is responsive to the system controller for generating an electro-magnetic field, the electro-magnetic field including a portion thereof characterized as a tracking volume (54) of highest accuracy. The highest accuracy corresponds to an accuracy of the sensor interface and system controller to detect a sensor (56) physically located within the tracking volume versus a lesser accuracy of the sensor interface and system controller to detect the sensor if the sensor is located outside of the tracking volume. The positioning and angular orientation configuration is coupled to the electro-magnetic field generator for visibly optimizing one or both of (i) a positioning and (ii) an angular orientation of the electro-magnetic field generator such that the tracking volume lies within a centroid of a physical volume of interest (66), thereby enabling a detection of a sensor within the tracking volume with a highest accuracy.
