A survey of electromagnetic position tracker calibration techniques

Abstract

l~his paper is a comprehensive survey of various techniques used to calibrate electromagnetic position tracking systems. A common framework is established to present the calibration problem as the interpolation problem in 3D. All the known calibration techniques are classified into local and global methods and grouped according to their mathematical models Both the location error and the orientation error correction techniques are surveyed. Data acquisition devices and methods as well as publicly available software implementations are reviewed, too.

Development and comparison of new hybrid motion tracking for bronchoscopic navigation

“…It is not easy to reduce the error of an EMT system that is usually comprised of two kinds of error: (a) static, and (b) dynamic. While static error can be partially corrected (Kindratenko, 2000), dynamic error caused, e.g., by ferromagnetic material (which also contains the bronchoscope) is difficult to correct, unless combined with optical tracking .…”

Navigated ultrasound in laparoscopic surgery

“…If there are disturbances that are constant and may be properly characterized, they may be compensated using static correction schemes (Chung et al, 2004;Kindratenko, 2000). These correction schemes require a set of distributed measurements within the tracking volume and corresponding reference measurements to compute a distortion function.…”

SPIDAR calibration using Support Vector Regression

“…Kindratenko [6] and Saleh [7] worked on a neural network based calibration of electromagnetic tracking systems and they obtained good results, better than with other methods.…”
