The First Responder is a portable neurodiagnostic device designed to rapidly identify strokes and traumatic brain injuries (TBI) at the point of care. Unlike traditional imaging methods that require hospital-based CT or MRI scans, this device enables on-site and in-transit diagnosis, significantly reducing treatment delays in time-critical emergencies. Designed for use in road and air ambulances, the First Responder is a lightweight, cost-effective solution that integrates with telehealth networks, allowing remote specialists to assist in real-time decision-making. By enabling early triage, transfer, and treatment, it improves patient survival rates and reduces long-term disabilities. With its unparalleled portability, affordability, and ease of integration into emergency care, the First Responder fills a critical gap in stroke and TBI diagnostics, making life-saving neuroimaging accessible to remote, rural, and anywhere CT or MRI are not available. It takes brain imaging to the point of first contact with patients. A world first.
