Wireless Frequency Domain Near Infrared Spectroscope for Cerebral Studies
Researchers at Tufts University have developed a miniaturized frequency domain near infrared spectroscope (mini-FD-NIRS) allowing for non-invasive measurements of absolute concentrations of oxy/deoxy-hemoglobin and other chromophores in patients and animals. Proof of concept experiments demonstrate that the measurements of chromophore concentrations obtained using this portable device are comparable to those obtained using bench top commercial instruments. This is the first example of a frequency domain near infrared spectroscope that could be worn by human subjects or animals for prolonged periods of time allowing for continuous monitoring of tissue oxygenation and metabolism.
