Hydrostatic-pressure-dependent acoustic properties of brain tissue and their implications in non-invasive ICP monitoring

Key Points

• Acoustic properties of brain tissue change significantly with hydrostatic pressure, impacting measurement accuracy.
• A notable increase in acoustic velocity was observed at varying pressures, stressing the need for calibrated assessments.
• Assessment of acoustic properties was evaluated through methods of fluid dynamics and biomechanics in a controlled environment.
• Highlights the potential for developing non-invasive techniques to monitor intracranial pressure, aiding clinical practices.
