摘 要：To realize three-dimensional optical imaging using transillumination images, we developed a novel technique to suppress the scattering effect in a transillumination image and reconstruct a three-dimensional image of the internal light-absorbing structure of animal body from two-dimensional images. The problem of the depth-dependence of PSF was solved by the calculation of the projection image in the filtered back-projection method. The feasibility and the effectiveness of the proposed technique were verified in the experiments with tissue-equivalent phantom and a living mouse. Using the proposed technique, the high-absorption organs such as kidneys and the bottom parts of the liver were reconstructed in a 3D image of mouse abdomen.
