Abstract:
A method for providing high fidelity reconstruction built on a grid having grid points of an observed sample, said method comprising the following steps:providing several recorded, observed data of the sample, each from a different aspect of the sample; providing an initial estimated densitiy distribution of the sample at the individual grid points; providing a blurred prior prejudice density distribution at the individual grid points using estimated data; calculating in an iterative process for each iteration: a new estimated distribution of the sample at the grid points using the prior prejudice density distribution and comparison between the estimated distribution in the next preceding iteration and the recorded, observed data of the sample, a new prior prejudice density distribution at the individual grid points on the new estimated distribution less blurred regarding the density distribution at the grid points than the prior prejudice distribution in the next preceding iteration; continuing the iterations until the difference between the new estimated distribution and the next preceding estimated distribution is less than a predetermined density resolution distribution condition on the grid points.
