Rapid access photographic recording material for medical radiography.

摘要

Photographic Ag halide (AgX) material for medical radiography, suitable for high-speed processing consists of a base with AgX emulsion layers applied to both sides and opt. ancillary layers. The novelty is that at least one AgX emulsion layer contains lamellar, spherical and/or almost spherical AgX crystals and has the parameter: W = Ng/(Ns x Nm) > (0.50-(Ar/1000) Mg = the total no. of Ag crystals per unit area; Ns = the no. of elementary layers of the AgX emulsion layer; Nm = the max. possible no. of AgX crystals of the AgX emulsion layer that can be present in one elementary layer; Ar = the fraction of AgX in this AgX emulsion layer in wt.%. Also claimed is a method of producing images with this material.
