Method of eliminating the effect of afterglow on a radiation image read out of a photostimulable phosphor screen. For each pixel the amount of afterglow generated by previously scanned pixels in the same line of pixels is determined and subtracted from the digital signal representation of that pixel.

Photosensitive image-forming element containing silver halide crystals internally modified with a metal-halogen-fluorine-complex

Emulsion, material and screen/film system for radiological image formation

A light-sensitive silver halide photographic emulsion has been disclosed, said emulsion comprising a binder and core-shell tabular grains, wherein said core is more rich in silver bromide than said shell, characterized in that said grains contain, in the core thereof representing an amount of precipitated silver halide extending up to less than 50% of all precipitated silver halide, a ruthenium complex compound as a sole complex compound providing shallow electron traps.

Shallow electron trap dopants in silver halide tabular grain emulsions for use in medical diagnostic imaging materials

A light-sensitive silver halide photographic emulsion has been described comprising a binder and tabular grains rich in silver bromide, characterized in that said grains contain as a dopant RhCl,(SCN),, wherein each of x and y are integers having a value of at least 1 and less than 6 so that x&plus;y equals 6.

Light-sensitive emulsion having tabular grains rich in silver bromide doped with thiocyanate complexes of rhodium

A photosensitive image-forming element has been provided, comprising on a support at least one photosensitive layer containing silver halide crystals which are internally doped with a transition metal complex (more preferably a metal halide chalcogenic cyanate complex, further called a `MHCC`-complex) forming a deep and permanent electron trap, wherein said transition metal complex satisfies the general formula (1) as disclosed in the claims and in the description.
