Abstract

We have developed a computer assisted neurosurgi-cal navigation system, which displays the point of on-going surgical manipulation on the CT or MR images. The system utilizes magnetic field modulation technolo-gy for the detection of the 3 dimensional position and orientation angles of the probe, a resin pointer or suc-tion tube with a small magnetic field sensor. Four fidu-cial markers on the scalp were used to translate the spatial data of the probe onto the CT/MRI images.
