Toward absolute quantification in CW-FDOT systems: use of a priori information

摘要

In the context of continuous wave fluorescence-enhanced diffuse optical tomography, we show that the reconstructed fluorescence depends on the local diffusion coefficient and demonstrate that the a priori knowledge of specific optical parameters may lead to the reconstruction of absolute quantification of the fluorophore distribution. In this context, we point out the potentiality of a bimodal instrument coupling functional and morphological information to provide knowledge of the distribution of optical parameters of internal organs. We show some quantitative results on simulated and experimental data on phantoms and conclude suggesting the use of optical parameters atlases to achieve an absolute quantification of fluorophore distribution in real contexts
