Where? Evaluation of Source-Detector Position in Spatially Resolved Spectroscopy
Keywords:Near-Infrared Spectroscopy, Spatially Resolved Spectroscopy, Tissue Oxygenation Index, Biosensing
Continuous-wave near-infrared spectroscopy (CW-NIRS) has found clinical use in monitoring tissue oxygen saturation, particularly in continuous monitoring of cerebral oxygenation in surgical patients. Recently, there has been interest in miniaturized, implantable NIRS sensors to directly interface with internal organs such as the spinal cord. This study establishes a starting point in assessing the effects of sensor miniaturization on NIRS-based oxygenation measurements.
