Abstract

Investigators have previously attempted to determine the optimal wavelengths to employ for Near-Infrared Spectroscopy (NIRS) which yield the best separation between absorption and scatter and the least influence of noise. Although these are important criteria it is also important that the volume of tissue sampled at each of the wavelengths is the same. In our study we have generated spatial sensitivity profiles at multiple wavelengths for a suitable model of tissue optical properties, and studied the spatial sensitivity overlap for different combinations of wavelengths. It is found that including this condition significantly influences the range of optimal wavelengths.
