Sources of errors in spatial frequency domain imaging of scattering media
Abstract:
Knowledge of the impact of potential sources of error in spatial frequency domain imaging (SFDI) is essential for the quantitative characterization of absorption and scattering in tissue and other turbid media. We theoretically investigate the error in the derived absorption and scattering parameter, subject to typical experimental and theoretical sources of errors. This provides a guideline to properly assess the significance of various parameters related to the measurement and the theoretical evaluation of spatial frequency domain reflectance data. At the same time, this study serves as a reference to estimate the overall precision of derived optical parameters of semi-infinite scattering media using SFDI.
