Abstract(in English) | Radiographic images obtained by the screen-film system have various noise called quantum mottle, structure mottle, and film granularity. It is well known that these noise affect the signal detectability. It is useful to analyze the statistical properties of radiographic noise in constructing of high performance x-ray imaging system. Authors present a random-dot model with triply Poisson process that can explain statistical properties of radiographic noise. Rigorous expressions of the mean transmittance and autocorrelation function of transmittance are obtained. Numerical examples show this model can explain the characteristics of experimental results in a practical screen-film system. |
