Quantum fluctuations in radiographic screen-film systems.
With the recent introduction of fast rare-earth screens into the market, the question of noise and how it influences image quality becomes particularly important. In this paper a compact formula involving familiar and measurable quantities is derived for the specification of the noise arising from the spatial fluctuations of the x-ray quanta absorbed in the screens. Experimental evidence in support of this concept is also given.
