New BrainZ algorithm 'quantum leap'

Auckland-based medical technology company BrainZ Instruments is hoping new software for detecting seizures will boost demand for its brain monitors.

The ASX-listed company has applied for US Food and Drug Administration clearance for the mathematical algorithm central to the software, which would trigger an alarm in the event of a seizure.

The algorithm will sell for about $5000 and, with about 170 neonatal intensive care monitors sold to date, the software upgrade could be worth about $850,000.

Chief executive Justin Vaughan said the real benefits, however, would be in widening the demand for BrainZ products.

"It is a quantum leap in terms of technology advancement," Vaughan said. "Also, the seizure detection method provides BrainZ with a core technology platform to springboard into wider markets, including adult areas."

The algorithm uses mathematical formulas to look for the repetitive activity spikes in normally random brain activity which could signal a seizure.

Vaughan said using algorithms to study activity and detect seizures "off line" was not new, but BrainZ' point of difference was to design software specifically for real-time bedside monitoring in neonatal intensive care.

"In that regard, we believe it is unique."
