Image processing method for a digital medical examination image, the pixels of which are assigned a gray-scale value in each instance, with a minimum and a maximum gray-scale value being defined as limit values for the purpose of displaying the examination image, with the pixels being subjected to an evaluation by means of a neural network, in order to determine such pixels and to disregard them when defining the gray-scale values which are located in a direct radiation region or in a projected collimator region.
