ABSTRACT:
A method for generating a radiation image signal comprises the steps of detecting an image signal by reading out a radiation image, which has been recorded on a recording medium during an image recording operation using a grid and which comprises an object image and a striped grid image corresponding to the grid and superposed upon the object image. The image signal is sampled such that a plurality of image signal components are obtained which correspond to a plurality of discrete points on the radiation image, intervals between the discrete points varying irregularly from predetermined intervals at least along a direction intersecting the striped pattern of the grid image on the radiation image.
