Abstract

The scattering effect in biological tissue is one of the most difficult problems to realize an optical computerised tomography (CT). To suppress the scattering effect in a reconstructed image, a fundamental study has been conducted on the deconvolution technique using a point spread function (PSF). The image blurring due to the scattering can be considered as the convolution of the PSF of a scattering medium. Therefore, if we can find an appropriate PSF, we can suppress the scattering effect by the deconvolution. To improve the deconvolution technique further, we have applied the frequency-distance relation to optical CT reconstruction and examined its effectiveness.
