From an initial image I.sub.lr (x) in the plane of a reference projection l.sub.r at a specific location along the system longitudinal axis and from an auxiliary image I.sup.d.sub.lr+1 (x) the computer recursively calculates a new image I.sub.lr+1 (x) at the distance d/N.sub.2.pi. from the initial image I.sub.lr (x) according to the equation:
