New Non-Invasive Device Measures Brain Health After TBI
On December 11, 2014 Tufts University announced the development and licensing of a new fiber-optic technology called CHS (coherent hemodynamics spectroscopy) to measure brain health after TBI, stroke or other brain trauma. The technology measures blood flow, blood volume, and oxygen consumption in the brain in real time in a non-invasive manner. It was invented by Tufts Professor of Biomedical Engineering Sergio Fantini. CHS works by attaching a fiber-optic device to the scalp which emits near infared light. Blood vessels in the brain absorb the light and then reflect it back to sensors. The data is interpreted by computer with the help of mathematical algorithms developed by Dr. Fantini to yield the desired information.
