NeuroSonic

NeuroSonic is a US-based medical device startup developing a handheld, non-invasive device for rapid stroke risk assessment at the point of care. The NeuroSonic device uses ultrasound-based technology to assess blood flow in the carotid arteries supplying the brain — a key indicator of stroke risk. Clinicians place the device on each side of a patient's neck; it analyzes blood flow and delivers instant insights via a companion app, helping clinicians determine whether further vascular imaging is needed. The system is designed to require minimal training and integrate with existing hospital systems. With 800,000 strokes occurring annually in the US and 80% estimated to be preventable, NeuroSonic aims to make stroke prevention faster and more accessible by bringing modern stroke-risk assessment into everyday clinical settings.
