摘要:
A method of imaging an interior of a turbid medium, for example a part of a breast of a human female, the turbid medium is irradiated with light and measurement of the intensity of light propagated along a plurality of light paths through the turbid medium is measured. An image of the interior of the turbid medium is reconstructed from the intensities measured. Furthermore, possible strengths assignable to each pixel of the image are determined from combinations of weighting functions and differences between expected photon fluences and a measured photon fluences from the intensities measured. A distribution function is made up from the possible strength determined. In a last step the image is determined from the distribution function. Further steps can be carried out to correct for objects of high strength in the image.
