Special Report: Compumedics has achieved a world-first breakthrough with its trademarked Neuroscan Orion LifeSpan magnetoencephalography (MEG) system – years in the making and with potential to transform surgery for brain function disorders, particularly epilepsy.
Compumedics (ASX:CMP), in collaboration with Beijing Fistar – the company's long-term Chinese distributor for its brain research technology – and Tianjin Normal University (TJNU), has recorded brain activity in children using its Orion LifeSpan MEG system.
Founder and executive chairman Dr David Burton said it marked the first time a single MEG system had delivered high-quality scans for both children and adults.
Burton said the 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 Neuroscan Orion LifeSpan MEG,' he said.
'The system represents a major leap in magnetoencephalography, with dual-helmet capability for paediatric 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.' Furthering its gold standard for brain analytics
MEG is a functional neuroimaging technique for mapping brain activity with highly sensitive detectors to record the naturally occurring magnetic fields produced by electrical current flows within the brain.
Compumedics has established a gold standard with its trademarked CURRY software, which Burton said had been used for decades at many MEG labs worldwide.
The CURRY software has a complete set of tools for efficient electroencephalography (EEG), magnetoencephalography(MEG) and event-related potential(ERP) recording, review and multi-modal integration.
'Compumedics now has the CURRY analytics software and MEG hardware fully integrated for seamless operations for the first time,' Burton said.
He said at the heart of Neuroscan Orion LifeSpan were patented and exclusive double relaxation oscillation superconducting quantum interference devices (DROS SQUIDs), offering unparalleled accuracy compared to conventional MEG sensors.
A special vacuum cooling system boosts sensitivity, while a virtually 100% helium recycling system means it can run continuously without needing refills, enabling 24/7 operation. Ability to accurately scan both children and adults
But among the key functions of the Neuroscan Orion LifeSpan MEG device is its unique dual-helmet design that allows accurate brain measurements for both adults and children – even at the same time (known as hyperscanning).
Compumedics' head of Orion global business Gordon Haid said a key principle of MEG was that because magnetic fields drop off very rapidly with distance, the sensors should be as close as possible to the sources of the brain signals.
'Since the sensors must be within a rigid helmet shape, a child's small head in an adult size helmet results in sensors far from the brain,' he said.
'This leads to small signals and a poor signal-to-noise ratio (SNR).'
Haid said a dedicated smaller helmet yields clearer and more accurate data for better research understanding and improved patient outcomes.

Haid said because many research and clinical MEG measurements must be done with children, most importantly for paediatric epilepsy diagnostics, several manufacturers have in the past produced systems with a paediatric optimised helmet.
'However, doubling the cost and space requirements to have a second system installed has made these types of systems a rarity,' he said.
For this reason, Compumedics, along with its technology partners at the Korea Research Institute of Standards and Science (KRISS), developed the unique Orion LifeSpan MEG with dual-sensing helmets.
'The system can be installed so that it rotates and fits within a standard-sized magnetically shielded room,' Haid said.

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.
'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,' Bai said.
'The system has already proven itself to be extremely sensitive, accurate and reliable.
'My team have been hard at work doing MEG measurements, analysing 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 transform surgery
Burton said the additional MEG brain function information, combined with traditional anatomical scanning such as MRI, provides an enhanced degree of accuracy and precision for critical brain surgeries, such as those related to epilepsy.
'By way of referencing the MEG brain function information, surgeons can help prevent damaging healthy brain material during complex surgical procedures,' Burton added.
'For example, the MEG brain function scans can help to identify critical brain control, sensory processing and other brain functional regions which are so important to avoid during delicate surgical intervention.
'This is particularly important in paediatric patients undergoing surgery, where identifying the small extent of the epileptogenic areas related to seizures can be critical to the child's outcome.'

Burton said Compumedics was firmly establishing itself as the dominant supplier of MEG technology in the Chinese neurosciences market.
The company has sold MEG systems to four prestigious universities in China in the first 18 months of its commercialisation to the value of ~$20 million.
The company recently announced it had received a new order from Hangzhou Normal University (HZNU) in China.
This follows a successful installation at TJNU and further orders from Tsinghua and Tianjin Universities.
'The take-up has proven quite extraordinary, especially given the strong barriers to entry,' Burton said.
Compumedics plans to expand into the North American market in 2025 and already has US Food and Drug Administration (FDA) certification. Known for its tech
Compumedics is well known for firsts in its technology and is highly regarded globally for its sleep-monitoring technology.
The company designed and installed the first Australian, fully computerised sleep clinic at the Epworth Hospital in Melbourne in 1987, the year it was founded.
Following early success, Compumedics went on to focus on development of products that sold into the burgeoning international sleep clinic and home monitoring of sleep markets.
Compumedics listed on the ASX in 2000 and has clients for its sleep-monitoring products in prestigious sleep centres globally.
It has counted NASA as a customer, winning two contracts for its first ambulatory sleep monitors for the organisation's space shuttle and space station programs.
The company also won a contract to equip the largest sleep study of its kind with about 14,000 patients.
'Whilst the company has celebrated many great achievements in the past, the brain is an incredibly complex organ, and this project has certainly been one of our most challenging,' Burton said.
'We're exceptionally proud of our achievements with the CURRY software and Neuroscan Orion LifeSpan MEG technology and what it represents as a major leap forward in understanding and treating the human brain.'

GWM's Cannon Alpha Ultra takes aim at the BYD Shark and Ford Ranger PHEV.

We're going to need a bigger boat. Originally established by BYD's Shark in 2024, the new class of plug-in hybrid utes has grown to include Ford's Ranger PHEV and the new GWM Cannon Alpha PHEV. China's GWM promises to split the difference between the affordable, road-biased Shark and Ford's deeply impressive (but similarly expensive) Ranger. Priced from $59,990 plus on-roads (about $63,000 drive-away) for the entry-level version, or $66,990 (about $70,000 drive-away) for the well-appointed Ultra, the Cannon takes the middle ground. Like for like, a GWM with a nice stereo and heated seats costs about $11,000 more than a similarly-specced Shark, or $20,000 less than a loaded Ranger Stormtrak hybrid. First impressions of the Cannon Alpha is that this is a big car – easily a size larger than the Ranger, particularly in the cabin. It looks a little odd, with a long wheelbase that lends unfamiliar proportions. That sense of the strange is amplified by a spare wheel mounted vertically within the tray, as the GWM's underfloor battery means there is no room for a conventional spare wheel. So you can lug it in the tray or leave it at home. But it's luxuriantly spacious on the inside, particularly in a back seat with plenty of legroom. High-end Cannons have a digital dash and head-up display augmented by a 14.6-inch central touchscreen. It has a 10-speaker stereo, wireless charging in the front and rear, and a 360 degree camera with 'see through' tech originally introduced by Land Rover for off-roading. The Cannon is loaded for bear on the luxury front, serving up heated and ventilated seats with a massaging function in the front, along with heated and vented seats with electric adjustment in the rear. While the list of features is extensive, some of the design choices – slabs of shiny fake wood, and a small analog clock – look out of place in 2025. Other head-scratchers include the spare wheel we've already mentioned, and a lack of power points in the cabin or tray. Instead, you have to buy a $230 power board with a special connection that goes into the car's charging port, then plug laptops or power tools into that. It also lacks easily accessible, clearly labelled controls for the hybrid system – most plug-in hybrids make it easier to go EV-only, preserve existing range or add to the battery's charge. More thought went into the Cannon's off-road hardware, which includes separately locking front, rear and centre differentials as well as a nine-speed automatic transmission with a low-range function. That's a great start for an off-roader. Then there's the 2.0-litre turbo petrol engine, a 180kW/380Nm unit that pairs with a 120kW and 400Nm electric motor to make a combined total of 300kW and 750 Nm. Again, those are good numbers. Having driven all three, it feels faster than the Ranger but not as zippy as the Shark – which drives more like a punchy electric vehicle than a hybrid-assisted machine. Other key numbers include a claimed 115km of electric driving range from a 37.1kWh battery that extends to a claimed 1060km of overall range if you fill the petrol tank. GWM claims official fuel use of 1.7L/100km, a figure that – like most plug-in hybrids – is almost impossible to match on the road. Budget on using about 10L/100km in the real world unless towing or off-roading. The Cannon looks set to do a better job of both than the Shark, which can't match its 3.5 tonne towing capacity or off-road hardware. GWM's 800mm of water wading depth and 210mm ground clearance promise decent off-roading performance, though it falls short of the payload claims of its hybrid rivals. Out on the road, GWM's big pickup feels as large as it looks, with relaxed steering and a long wheelbase that lend stability, but make it feel a little unwieldy in town. Soft suspension rides well while returning more roll than you might expect, and there's an occasional delay in throttle responses that can frustrate from time to time. Verdict GWM's Cannon Alpha is an impressive machine that will have people think twice about a conventional ute, but it lacks the star factor of the more affordable Shark or more polished Ranger.

Stocks rise ahead of US-China talks outcome

Stocks are buoyant and the dollar remains on guard as trade talks between the United States and China are set to extend to a second day, with tentative signs tensions between the world's two largest economies could be easing. US President Donald Trump put a positive spin on the talks at Lancaster House in London, which wrapped up for the night on Monday and were set to resume on Tuesday (7pm AEST). "The fact that we're still up here near record highs, does suggest that we are seeing the market accept what has been said by Trump and when you look at some of the other comments from Lutnick and Bessent, to me it seems to suggest that they are relatively happy with the progress," said Tony Sycamore, a market analyst at IG. "But the market always likes to see some concrete announcements." As Treasury Secretary Scott Bessent, Commerce Secretary Howard Lutnick and US Trade Representative Jamieson Greer were set to meet for the second day with their Chinese counterparts, much of investors' focus has been on the progress of the talks. Any progress in the negotiations is likely to provide relief to markets given Trump's chaotic tariffs and swings in Sino-US trade ties have undermined the world's two biggest economies and hobbled global growth. MSCI's broadest index of Asia-Pacific shares outside Japan advanced 0.5 per cent, while Nasdaq futures gained 0.62 per cent. S&P 500 futures edged 0.43 per cent higher. EUROSTOXX 50 futures and FTSE futures both added roughly 0.1 per cent each. In Tokyo, attention was also on the Japanese government bond (JGB) market, following news that Japan is considering buying back some super-long government bonds issued in the past at low interest rates. The yield on the 10-year JGB fell one basis point to 1.46 per cent in early trade, while the 30-year yield slid five bps to 2.86 per cent. Yields on super-long JGBs rose to record levels last month due to dwindling demand from traditional buyers such as life insurers, and jitters over steadily rising debt levels globally. "The volatility at the super-long segment of the curve stems from a supply-demand imbalance that has been brewing since the BOJ embarked on balance sheet normalisation," said Justin Heng, APAC rates strategist at HSBC Global Investment Research. Japanese Finance Minister Katsunobu Kato said on Tuesday the government would conduct appropriate debt management policies while communicating closely with market participants. In currencies, the dollar attempted to regain its footing after falling on Monday. Against the yen, the dollar was up 0.45 per cent to 145.25. The euro fell 0.28 per cent to $1.1387 while sterling slipped 0.2 per cent to $1.3523. Trump's erratic trade policies and worries over Washington's growing debt pile have dented investor confidence in US assets, in turn undermining the dollar, which has already fallen more than eight per cent for the year. The next test for the greenback will be on Wednesday, when US inflation data comes due. Expectations are for core consumer prices to have picked up slightly in May, which could push back against bets of imminent Federal Reserve rate cuts. The producer price index (PPI) report will be released a day later. "May's US CPI and PPI data will be scrutinised for signs of lingering inflationary pressures," said Convera's FX and macro strategist Kevin Ford. "If core CPI remains elevated, expectations for rate cuts could be pushed beyond the June 18 FOMC meeting." Traders see the Fed keeping rates on hold at its policy meeting next week, but have priced in roughly 44 bps worth of easing by December. In the oil market, prices edged up, with Brent crude futures gaining 0.24 per cent to $US67.20 ($A103.09) a barrel. US West Texas Intermediate crude was last up 0.25 per cent at $US65.45 ($A100.40) per barrel after hitting a more than two-month high earlier in the session. Spot gold fell 0.5 per cent to $US3,310.40 ($A5,078.22) an ounce.
