Abstract

Light scattering in highly scattering turbid media can be well described as diffuse photon density wave. Based on this principle, the K-space approach is introduced which is essentially a near field technique relying on a series of two-dimensional fast Fourier transforms. A rigorous theoretical account, along with the first experimental images of absorbing and scattering objects in turbid media, demonstrates that, in addition to producing information about the position and shape of the hidden objects, it is possible to utilize projection images to deduce the optical properties within a thin slice without the need for complex reconstruction procedure such as matrix inversion, and thus, the possibility to obtain clinical projection images.
