ABSTRACT:
In a radiation image processing apparatus, signal processing for determining the shape and location of an irradiation field, adjusting read-out conditions for a final readout from a preliminary read-out image signal, adjusting image processing conditions, and/or detecting an abnormal pattern is carried out on an image signal representing a radiation image by using a neural network. After the neural network, the learning operations of which have been carried out, is incorporated into the radiation image processing apparatus, modifying information is entered from an input device into the neural network. The modifying information is used to modify the signal processing carried out by the neural network and thereby to carry out re-learning operations of the neural network.
