Scattering suppression in cylindrical turbid medium for transcutaneous fluorescent imaging through animal tissue

To improve the transcutaneous fluorescent image of an animal body, we derived a point-spread function (PSF) at a cylindrical surface of a turbid medium. In this technique, distortion problem of the restored shape remained. For this problem, new scattering suppression technique using the PSFs divided into the symmetric and asymmetric components was developed. The usefulness of the proposed technique was examined in experiment with biological tissue. The internal fluorescent object, which was hardly seen in the image from observed images, became visible by the proposed technique. Through this analysis, the applicability of the proposed technique to biological tissues was verified.
