Abstract
A method and system for the direct reconstruction of an object (610) from measure-ments of the transmitted intensity (710) of the scattered radiation effected by irradiating the object. The transmitted intensity is related to the image by an integral operator. The image is directly reconstructed (730) by executing a prescribed mathematical algorithm, as determined with reference to the integral operator on the transmitted intensity.
