抄録
A theoritical investigation of the image quality evaluation of asymmetric screen-film systems is developed. In connecting with the front and back side image of a film, it is helpful to assess the image quality by keeping in mind that an asymmetric screen-film system involves radiographic density rather than optical illuminance. Therefore, overall MTF depends on radiographic density comprising parallel linkage of each side MTF with relative gradient weight of an asymmetric screen-film system. Slit and chart measurement methods of MTF for asymmetric system are discussed. Consequently, it can successfully be to evaluate the image quality of the simulated asymmetric system by NEQ (u).
