    Abstract: An ultra-high-speed radiographic imaging assembly (at least 900 system speed) is useful especially for pediatric radiography to provide images with improved contrast and sharpness and reduced fog. The imaging assembly includes a symmetric film having a speed of at least 400 that includes at least two silver halide emulsion layers on each side of a film support that comprise tabular silver halide grains. The imaging assembly also includes two fluorescent intensifying screens wherein the pair of screens has a screen speed of at least 400 and the screens have an average screen sharpness measurement (SSM) value greater than reference Curve A of FIG. 4. The screens can have a support that includes a reflective substrate comprising a continuous polyester phase and microvoids containing inorganic particles dispersed within the polyester phase.

    Abstract: The invention provides a photographic element comprising at least one emulsion layer comprising at least 50 mol% silver chloride, which layer comprises at least one DIR coupler in association with at least one image dye-forming coupler, characterised in that the relative reactivity ratio krel of at least one DIR coupler and an associated image coupler is less than or equal to 1.0, wherein krel = k1/k2; k1 = the second order rate constant for the reaction of DIR coupler with oxidised developer and k2 = the second order rate constant for the reaction of image coupler with oxidised developer. The DIR couplers when associated with image couplers such that the above condition is satisfied efficiently reduce development of silver halide emulsions containing at least 50 mol% silver chloride, there being a reduction in contrast providing a linear sensitometric curve over a good latitude with negligible speed penalty.

    Abstract: Ammonium pentachloromonoaquorhodate(III), (NH4)2RhCl5(H2O), is a useful photograpic chemical. Small amounts of rhodium-containing, water soluble species remain in solution in the process liquor after synthesis. Most of the soluble rhodium values are present as the aforementioned ammonium complex; however there are traces of the cis and trans isomers of ammonium tetrachlorodiaquorhodate(III), and traces of the fac and/or mer isomers of rhodium(III) chloride triaquo complexes. Rhodium values present in the liquid as ammonium pentachloromonoaquorhodate(III) can be recovered by the addition of cesium chloride to form a precipitate identified as Cs2RhCl5(H2O). Very little of the aforementioned fac and mer isomers or other contaminants, if any, are contained in the precipitate. The cesium rhodium pentachloride monohydrate product can be refined, for recovery of rhodium values, or used as an additive to a silver halide emulstion to control fog or stabilize the emulsion.

    Abstract: Thermally developable compositions, such as photothermographic emulsions, include certain stabilizing polycarboxylic acid compounds and ascorbic acid or reductone reducing agents. These compositions can be used in thermally developable materials such as photothermographic materials to reduce changes in Dmin, Dmax, and photospeed upon storage. Such materials can have thermally developable imaging layers on one or both sides of the support and be arranged in association with one or more phosphor intensifying screens in imaging assemblies. These imaging assemblies can be exposed to X radiation and thereby excited to form a latent image in the photothermographic material that can eventually be used for medical diagnosis.

    Abstract: A photographic emulsion is disclosed comprised of a dispersing medium and radiation-sensitive silver halide grains with greater than 50 percent of total grain projected area being accounted for by grains containing a host portion of a face centered cubic rock salt crystal lattice structure and a first epitaxial phase containing greater than 90 mole percent iodide. The host portion is tabular, being bounded by an exterior having first and second parallel major faces joined by a peripheral edge. The first epitaxial phase accounts for less than 60 percent of total silver, and the first epitaxial phase is restricted to a portion of the exterior of the host portion that includes at least 15 percent of the major faces.
