Brain Imaging for Stroke

EMVision Medical Devices Ltd

One in six people will have a stroke in their lifetime. It is a leading cause of death and disability worldwide. EMVision together with researchers at the University of Queensland (UQ) and Tiller Design have developed the world’s first truly portable and easy to use prototype brain imaging solution that will vastly decrease the time to diagnose and treat stroke.

Tiller Design, in collaboration with EMVision and UQ, iteratively developed multiple headset arrays and system architectures, culminating in a proof of concept device design within 18 months. Developed under ISO 13485 design controls, two units were deployed to Princess Alexandria Hospital and produced highly promising images in comparison against gold standard imaging (CT and MRI). This world leading project has now transitioned to formal design and development of the first commercial device. For up to date information visit

The first generation commercial device is being developed for use in clinical environments (ICU, Stroke and Neurology wards), allowing clinicians to make critical decisions and interventions earlier, when time matters. In collaboration with the Australian Stroke Alliance, a miniaturised second generation device is being developed for use by paramedics in road and air ambulances, to deliver the most effective treatment to patients within the ‘Golden Hour,’ regardless of their location.
