Method and apparatus for radiation image processing and x-ray image processing.

摘要

In a radiation image processing method, unsharp mask signals Sus.k are calculated by averaging original image signals detected within predetermined ranges surrounding each scanning point on an image-recorded stimulable phosphor, and at least a single attenuation coefficient beta l among attenuation coefficients beta k corresponding to the unsharp mask signals Sus.k is adjusted to be a constant within the range of 0< beta l wherein beta l NOTEQUAL 1. An operation represented by a formula <MATH> where Sb1 and Sb2 each denote the original image signal or an image signal obtained by intermediate processing of the original image signal, and S min denotes an image signal obtained by the operation processing is carried out by use of the attenuation coefficient beta l , whereby spatial frequency components above the spatial frequency component which the unsharp mask signal Sus. l corresponding to the attenuation coefficient beta l has are attenuated.
