Introduction: The dynamic nature and three dimensionality of ultrasound data can be utilized to enhance the capabilities of image guidance systems. Methods: Coregistration of ultrasound data was done using an electromagnetic digitizer, and subsequent ultrasound images were correlated with preoperative MRI studies. Thirty-two patients undergoing craniotomy were investigated in this manner. Results: Phantom testing done with a rigid stylus and 3D ultrasound tracker demonstrated an accuracy of 1.36 ± 1.67 mm in determining the location of a point. Thirty-two clinical cases were coregistered without difficulty. Conclusion: Coregistered ultrasound is a useful methodology that can aid in neuronavigation. Copyright (C) 2000 S. Karger AG, Basel.
