Compumedics Achieves World-First Adult and Child Optimized Recordings from a Single MEG System

Compumedics Limited (ASX: CMP), a world leading supplier of innovative medical technology for patient monitoring, has in collaboration with Beijing Fistar and TJNU performed recordings of both adults and children. The site at TJNU is equipped with an Orion LifeSpan™ MEG.

‘Most advanced MEG capability anywhere in the world’

Professor Xuejun Bai is Vice President of TJNU, Head of the MEG Laboratory, Director of the Brain Functional Imaging Centre and former Director of the Chinese Psychological Society. He has published more than 300 scientific papers and has been awarded ten patents. Prof. Bai commented:

“The Orion LifeSpan MEG recently installed by Compumedics at TJNU has been a revolution in our ability to study mental processes of both children and adults, or even the two simultaneously. The system has already proven itself to be extremely sensitive, accurate and reliable. My team have been hard at work doing MEG measurements, analyzing the resulting data and uncovering new neuroscientific findings. I can say without reservation that the Orion LifeSpan has given TJNU the most advanced MEG capability anywhere in the world.”

Ability to Accurately Scan Both Children and Adults

MEG is a functional neuroimaging technique for mapping brain activity. It uses highly sensitive detectors to record the naturally occurring magnetic fields produced by electrical current flows within the brain. Because magnetic fields drop off very rapidly with distance, the sensors should be as close as possible to the sources of the brain signals. A child’s small head in an adult size helmet results in sensors far from the brain, leading to small signals. A dedicated smaller helmet yields clearer and more accurate data. More precise data always leads to better research understanding and improved patient outcomes.

World’s First Recordings

After installation of the Orion LifeSpan™ MEG at TJNU, a series of measurements were undertaken to demonstrate that the theoretical advantage of the system during pediatric recordings would be borne out in practice.

Founder and Executive Chairman Dr David Burton commented: “These recordings represented the first time a single MEG system had delivered high-quality scans for both children and adults. This breakthrough was at the world’s most advanced MEG lab at TJNU, which is equipped with a Compumedics Orion LifeSpan MEG system.

“Compumedics has invested nearly a decade and many millions of dollars to develop the Orion LifeSpan MEG,” he said. “The system represents a major leap in magnetoencephalography, with dual-helmet capability for pediatric and adult brain scanning, fully integrated with our gold-standard brain analytics CURRY software.

“It’s incredibly rewarding to see these efforts translating into strong initial sales, global interest and the potential for improved brain health, among both children and adults worldwide.”

A four-year-old female was presented with a series of tones and measured with both the adult and pediatric helmet. The results showed significantly stronger detection in the pediatric helmet. Localizations showed more precise determination of where the brain had been activated by the tones. The physics of magnetic field decay and the design philosophy of the Orion LifeSpan™ MEG were confirmed
