Transcranial Doppler Remote Positioning System with Virtual Reality Integration for Vestibular Studies

Area of Science:

• Neuroscience
• Biomedical Engineering
• Medical Devices

Background:

• Transcranial Doppler (TCD) ultrasound is crucial for cerebral blood flow (CBF) studies.
• Maintaining consistent TCD probe pose is essential but challenging during motion-based vestibular research.
• Probe displacement during experiments can lead to prolonged study durations or termination.

Purpose of the Study:

• To design and develop a mechatronics system for remote TCD probe repositioning.
• To overcome the challenge of probe displacement in integrated CBF and vestibular studies.
• To enable simultaneous data collection for CBF velocity and virtual reality-based vestibular assessments.

Main Methods:

• Development of a novel mechatronics apparatus for TCD probe manipulation.
• Integration of the system with a head-mounted virtual reality (VR) display and a vestibular disorientation device.
• Testing and validation of the remote repositioning capability during simulated experimental conditions.

Main Results:

• Successful design and prototyping of the mechatronics system.
• Demonstration of remote, real-time TCD probe repositioning capability.
• Facilitation of uninterrupted data collection during VR-integrated vestibular experiments.

Conclusions:

• The developed mechatronics apparatus effectively addresses TCD probe displacement issues.
• This system enables robust integration of cerebral blood flow measurements with advanced vestibular research.
• It opens new possibilities for motion-based studies combining CBF velocity and VR technologies.
