Abstract
The applicability of optical methods for generating physiological data within a patient's body is being studied. There are two principal fields of optical monitoring: spectroscopy and imaging. Meanwhile there are two main variables to be considered in optical transillumination measurements are absorption and scattering. In spectroscopy, the average optical parameters over a large area of the body is sought while in imaging, the main goal is to achieve a spatially resolved mapping of the optical properties of the tissue section being examined. A finite element model was employed to facilitate the minimization of errors and to obtain uniformity in the methodology for a stabilized solution.
