Bringing imaging to where stroke occurs will save lives
Stroke is a global societal & health economic burden
Effective treatments available
They are time sensitive and require urgent brain imaging first
What clinicians need to know…
The ability to distinguish stroke type, size, severity and location, in a timely manner, is crucial to enable successful stroke treatment. Ischaemic stroke patients can benefit from clot dissolving drugs and clot retrieval. The EMVision technology opens the door for the earlier diagnosis and better bedside management of stroke patients.
1st Generation Device
Detect clinically significant changes, at the bedside, when time matters.
2nd Generation Device
Ultra light weight device embedded in standard road and air ambulances to deliver pre-hospital stroke diagnosis and care to patients regardless of location.
This is an artistic concept of a proposed first responder device which is subject to prototype development and clinical testing.
1st Gen device under development and its potential clinical utility is also subject to successful clinical testing and validation.
There is an unmet need for pre-hospital and bedside imaging for stroke.
A typical patient journey & time line
Bringing neuroimaging to the patient, wherever they are
PortableEasily manoeuvred, easily stored, just like a cart Ultrasound
SafeNo ionizing radiation, no ferromagnetism, no special infrastructure or shielding requirements
Bedside operationPerform scans at the bedside, without needing to move equipment or transport the patient
FastScans completed in under 30 seconds, quality images in just a few minutes.
Easy to operateOne headset for all head sizes, simple pre-set positioning, push to scan.
AntennasArray of proprietary antennas send pulses of low-power electromagnetic waves into the head.
HeadsetWaves penetrate tissue in a non-ionizing and harmless manner and are scattered based on the dielectric properties of tissue. Sensors in the helmet detect these complex interactions. The reflections are not dissimilar to those of the sound waves in ultrasound, but because the EM waves are of much higher frequency, they have more complex interactions. Anatomical dielectric properties are mapped.
Point-of-care NeuroimagingA powerful fusion of physics and data science-based techniques generate an image of the patient's brain, with artificial intelligence powered decision support.
Latest EMVision imaging case studies
The EMV images are obtained by inferring the electrical properties of tissues, on the basis of their complex and differing interactions with ultra high frequency radio signals in the spectrum 0.5 – 2 GHz. In these examples proprietary algorithms leverage the clear differences in the electrical properties of tissues impacted by hemorrhage to determine ‘blood or not’
