BROOKLYN — NYU Tandon researchers have developed a new algorithm that reconstructs microwave brain images 10–30 times faster than current methods – a breakthrough that could allow portable, helmet-sized scanners to diagnose strokes in under a minute.
The technique, published in IEEE Transactions on Computational Imaging, trims reconstruction times from nearly an hour to under 40 seconds by rethinking the math behind microwave imaging and streamlining the amount of computation needed. The advance could enable clinicians to distinguish between clots and bleeds without CT machines, expanding stroke care to ambulances, rural clinics and low-resource hospitals.
Researchers say the speed boost also opens doors for applications in breast cancer screening and ICU monitoring.
