Multi-wavelength diffuse optical imaging: Experimental results

Summary form only given. A primary goal of diffuse optical tomography is to image blood volume fraction and blood oxygen saturation levels. The space-varying absorption coefficient can be used to examine these two quantities, but illumination at multiple wavelengths is required in order to distinguish between oxy- and deoxy-hemoglobin. In this work we investigate a number of approaches to explore how to most effectively combine the information from multiple wavelengths. We examine the problem in a three-dimensional geometry for reflection imaging with a relatively small support of transmitters and receivers.
