Method for correcting magnetic resonance image distortion for frame-based stereotactic surgery, with preliminary results. Journal of image guided surgery Sumanaweera, T. S., Adler, J. R., Glover, G. H., Hemler, P. F., van den Elsen, P. A., Martin, D., Napel, S. 1995; 1 (3): 151-157


We previously described a technique for correcting patient-specific magnetic field inhomogeneity spatial distortion in magnetic resonance images (MRI), which was not applicable to patients fitted with MRI-compatible stereotactic fiducial frames. Here we describe an improvement to the technique that permits application for these patients. Measurements with a cadaver head show that this method achieves MRI stereotactic localization accuracy of 1 mm.
