Abstract
An image reconstruction method for reconstructing an image fmin representing a region of investigation within an object includes providing detector data (yi) having Poisson random values from an X-ray transmission measurement using an X-ray source and a detector device, the detector data (yi) being measured at an i-th of a plurality of different pixel positions of the detector device relative to the object, and reconstructing the image fmin based on the detector data (yi), the reconstructing step including a procedure of minimizing a functional
