LEDs may replace magnetism and radiation for neuroimaging

When doctors want to monitor someone's brain activity, they generally use either functional magnetic resonance imaging (fMRI) or positron emission tomography (PET). One subjects the patient to strong magnetic fields, while the other involves radiation exposure. Scientists at Washington University in St. Louis, however, have recently had success using diffuse optical tomography (DOT). Although it may look kind of extreme, it basically just involves shining LEDs into the subject's head. .. Continue Reading LEDs may replace magnetism and radiation for neuroimaging
