EMVision Medical Devices (ASX:EMV) says it has made two breakthroughs that will let its mobile imaging devices better diagnose strokes in the field.

The company has produced high fidelity images of brain structures so that field clinicians can better assess stroke impact, the company said.

“The dielectric maps will have a dramatic impact on the interpretation of data from our algorithms,” said EMVision chief executive Dr Ron Weinberger.

“For the first time using EM imaging, clinicians will be able to make good approximations to the anatomical region at which stroke occurs and will enable a visualisation of the EM image for clinicians that is familiar to them and what they have been looking at for decades, CT and MRI.”

Also, a new method of processing signal data from its mobile scanners will enable the devices to early identify stroke victims suffering a large vessel occlusion, a blockage of one of the major arteries in the brain, EMVision said.

The technique could be used to measure blood flow through the brain, identifying the degree of blockage at the earliest stages and therefore avoiding devastating treatment delays.

“Pulsatility is a complementary technique that alongside our existing diagnostic algorithms, has the potential to improve diagnosis and treatment and save more lives,” Dr Weinberger said.

At 10.59am, EMV shares were up 0.3 per cent to $3.04. It has risen by 16 per cent in the past month, and is up a massive 265 per cent in the last 12 months.
