In a radiation image processing method utilizing a neural network, an image signal representing a radiation image is fed into a neural network, image processing is carried out on the image signal by the neural network, and an output representing the results of the image processing is obtained from the neural network. Image processing, with respect to the whole region of the radiation image, is carried out on the image signal by a first group of neurons of an intermediate layer of the neural network. Image processing, with respect to parts of the region of the radiation image, is carried out on the image signal by a second group of neurons of the intermediate layer of the neural network. Regardless of set values of initial conditions, the output of the neural network becomes converged to a global minimum corresponding to the stored information, and the results of operation obtained from the neural network are not trapped at a local minimum.
