Visual Restoration Using Focused Ultrasound Stimulation and Immersive Virtual Reality After Stroke

Low-intensity focused Ultrasound (LIFU) is a noninvasive brain stimulation technique that uses low-intensity ultrasound to stimulate specific parts of the brain.

IVR is a noninvasive, computer-based audiovisual therapy designed to enhance visual function. Using a VR headset, the system delivers targeted visual stimulation through an interactive game that the participant engages with during each session.

High acoustic impedance disk placed between LIFU and scalp that mimics the audible sensation of a slight buzzing but attenuates more than 95% of the energy into the brain.
