Total imaging process consists of radiographic, display and sensory imaging process, it is therefore difficult problem that we derivate a function evaluating the image quality of radiography, only by means of the three phisical factors (sharpness, graininess and contrast) of radiographic imaging process. Ultimately total evaluation of the image quality of radiography makes necessary applications of signal detection theory involving even human decision principle. In this study, Signal Detection Theory composed of probability, statistics and information principle is fundamentally developped for to prepare describing uniformly each process from X-ray pattern to sensory image.
