Abstract (in Japanese) (See Japanese page) 
(in English) For evaluation of digital X-ray images, spatial frequency analyses are mainly performed under assuming linearity of system. However, this evaluation method has been used without ample studies of the linearity. In this study, we verified nonlinearity of the digital X-ray images by using method of surrogate and Wayland test, which was one of the nonlinear analyses. As a result of experimentation, the nonlinearity was found in horizontal direction to the X-ray tube on the X-ray images. On the other hand, the linearity was found in vertical direction to the X-ray tube.
