New technology from the Tufts University School of Engineering will allow for real-time brain circulation imaging without any invasive impact on patients, enhancing both intensive treatment options and general brain monitoring. Coherent hemodynamics spectroscopy (CHS) is a technique that measures blood flow, volume and oxygen consumption within the brain by using fiber optics to project near-infared light into the scalp. The light is then absorbed by cells throughout the brain before being reflected back into sensors, which use mathematical calculations to form a real-time movement map of the brain’s circulation. This process is described as non-invasive and low-impact for the patient, usable in a wide variety of applications to monitor various aspects of brain health. “CHS is based on measurements of brain hemodynamics that are interpreted according to unique algorithms that generate measures of cerebral blood flow, blood volume and oxygen consumption. This technique can be used not only to assess brain diseases but also to study the blood flow and how it is regulated in the healthy brain,” said the inventor.
