Slide 7: Stroke in Australia
Stroke in Australia For personal use only • One stroke occurs every 19 minutes. • 24% of first ever stroke occur in peoples aged 54 years and under • It is estimated that in 2020, the cost of stroke was $6.2 billion in direct financial impact, and a further $26.0 billion in mortality and lost wellbe

Slide 10: The solution
The solution For personal use only The development of portable brain scanners, taken to the patient, either by road or air, combined with telehealth support to diagnose and treat acute stroke. Clinical Prototype In-hospital Pre-hospital system used in Brain Imaging Brain Imaging first trial The conc
Slide 11: What is electromagnetic imaging
What is electromagnetic imaging For personal use only • Electromagnetic (EM) imaging transmits low energy electromagnetic waves. • Images are obtained by processing signals from encircling transceiver antennae which emit and detect low energy signals in the microwave frequency spectrum between 0.5 a
Slide 12: Dielectric properties, permittivity and conductivity
Dielectric properties, permittivity and conductivity For personal use only • Electromagnetic imaging (EMI) is based on characteristic and recognizable dielectric properties of tissues. • The head contains many structures with different dielectric properties. Permitting localisation and characterisat

Slide 16: Pilot study aim
Pilot study aim For personal use only • To assess the impact of stroke on electromagnetic scattering effects on the brain
Slide 17: Methods
Methods For personal use only • Prospective, observational, open, non-interventional pilot study, conducted at the Princess Alexandria Hospital in Brisbane, QLD Australia. • Patients with imaging-proven ischaemic (IS) or haemorrhagic (ICH) within preceding 48 hours were recruited. • EMI was performe
Slide 18: Methods
Methods For personal use only • Images were obtained by the encircling transceiver antennae contained in a 25lbs helmet. • Localisation was assessed by determining whether fusion images resulted in target detection in the same quadrant as comparable CT or MRI. • EM images were reconstructed by creat
Slide 19: Results
Results For personal use only • 50 patients, 37 IS and 13 ICH confirmed. • Mean age 67.7 years (range 41-92), 57% were female. • Mean NIHSS 5.9 • Mean time to routine imaging was 12.5 hrs (range 1- 128) and to EMI 24 hrs (range 6-142). • EMI algorithms differentiated ICH from IS with 98% accuracy an
Slide 20: Limitations
Limitations For personal use only • All patients included had a confirmed stroke, therefore early stroke assessment by the EMV scanner has not been captured in this study • Small sample size prohibits meaningful statistical analysis; however, the study was not designed to assess the EMV scanner head
Slide 21: Conclusion
Conclusion For personal use only • In this early study, we show the ability of the modality to distinguish between IS and ICH and stroke location. • Further developments may produce a valuable imaging tool to assist in prehospital and bedside stroke diagnosis and management. Further information on t
Slide 22: The future
The future For personal use only • A next generation device with advanced hardware and software is currently being manufactured • Further clinical trials, with a larger patient population are being developed. • Subject to the clinical trials, the technology will be trialled in the pre-hospital setti
