  • Patent number: 5536631
    Abstract: The invention relates to a fast-processing photographic recording material for medical radiography which can be processed within 30 to 60 seconds in a film processor. The recording material comprises a silver halide emulsion layer applied to each side of a carrier; wherein at least one of the silver halide emulsion layers comprises silver halide grains or crystals with a morphology which is chosen from a set consisting of plate-like or platelet shaped, spherical and approximately spherical; and the silver halide emulsion layer is described by the equation:W=N.sub.g /(N.sub.s *N.sub.m)wherein:N.sub.g is the total number of silver halide crystals per surface unit; N.sub.s is the number of elementary layers of the silver halide emulsion layer; and N.sub.m is the maximum possible number of silver halide crystals of the silver halide emulsion layer that can be contained in an elementary layer; and W is also defined by the equation:W>(0.5-A.sub.r /1000)wherein:A.sub.
