Area of Science:

Neurosurgery
Medical Imaging
Surgical Navigation

Background:

Stereotactic neuronavigation traditionally relies on preoperative imaging like MRI or CT.
Intraoperative imaging offers real-time updates but integration challenges exist.

Purpose of the Study:

To describe a novel two-rack prototype integrating neuronavigation with an ultrasound scanner.
To present results on image quality enhancement for intraoperative ultrasound-based navigation.

Main Methods:

Development of a single-rack system combining a high-end ultrasound scanner, computer, and optical positioning system.
Implementation of a special interface for rapid, lossless transfer of 3D ultrasound data.
Tracking of patient, probe, and instruments for real-time 3D map updates.

Main Results:

Image quality improvements allow extraction of clinically valuable information from intraoperative ultrasound, comparable to preoperative MRI.
The ultrasound-based navigation system demonstrates clinical accuracy expected to be comparable to or better than MRI-based systems.
Successful clinical testing of the prototype at the University Hospital in Trondheim since 1997.

Conclusions:

The SonoWand system enables neuronavigation using intraoperative 3D ultrasound.
Further research is needed to fully explore the clinical potential and limitations of this ultrasound-based neuronavigation technology.
