Portable detector can detect concussion right on the field

In good news for athletes or cricketers who suffer concussion on the field, a team of doctors and engineers has developed a noninvasive way to measure whether brain cells are in distress using an infrared laser. There’s no scan, no blood test, no computer test,” said Steven Broglio, director of the Michigan Concussion Center and professor, athletic training. “It could help patients whose blood pressure falls so much that there isn’t enough blood flow to keep cells functioning normally,” said Russo. “Hemoglobin, which tells us about the blood oxygen levels, also responds to the range of wavelengths we use to probe CCO, and it is 10 to 20 times more plentiful in human tissue,” explained Mohammed Islam, professor of electrical engineering and computer science.
