发明名称 Method and device for imaging the interior of a turbid medium
摘要 A method and device of imaging an interior of a turbid medium is disclosed for reconstruction of biomedical images consecutive irradiation of the turbid medium with light from a light source from a plurality of positions and detection of the light propagated along a plurality of paths through the turbid medium. The method starts with a simple back-projection algorithm to get a first image. Then in next steps this image is corrected by deconvolution with a spatially varying convolution function. This convolution function is based on the scattering and coefficients of the turbid medium and the propagation of the light in the turbid medium. A second correction approach is obtained by means of a coordinate transformation. Advantages of the method according to the invention are that the method is rather easy to implement, the method needs only a few iteration steps to obtain corrected images and the method does not suffer from instability problems.
