Portable Visor Accurately Detects Strokes
For stroke victims, early diagnosis and treatment is critical for a good prognosis. Cerebrotech Medical Systems in Pleasanton, California has developed a portable visor that can diagnose strokes with up to 92% accuracy. The visor uses a technique called volumetric impedance phase shift spectroscopy (VIPS) and involves sending low-energy radio waves through the brain and then detects how the wave frequency changes as they pass through the two brain lobes.
