摘要:
A target (10, 20) is disclosed suitable for setting the exposure and white balance of a photographic digital camera. The target (10, 20) comprises a target surface (12) that has a reflectance of 18% for all wavelengths of visible light. The target surface (12) is provided with a feature (16) upon which the camera is able to focus.
摘要:
A silver salt photothermographic dry imaging material including non-photosensitive aliphatic carboxylic acid silver salts; a photosensitive emulsion containing photosensitive silver halide grains; a silver ion reducing agent; a binder; and a cyan coloring leuco dye. A percentage of the photosensitive silver halide grains having a mean particle size of 0.01 or more μm and 0.04 μm or less is 5% or more by mass and 50% or less by mass of total photosensitive silver halide grains by conversion into a silver amount.

A photographic film with a row of sprocket holes formed on each side thereof includes a sensitometric step wedge of different light intensity values exposed along one side of the film, preferably located between the sprocket holes.
摘要:
The present invention provides a photothermographic material including, on at least one surface of a support, an image forming layer comprising at least a photosensitive silver halide, a non-photosensitive organic silver salt, a reducing agent for silver ions and a binder, wherein (1) the photothermographic material has means for nucleation, and (2) an average gradient of a photographic characteristic curve thereof is from 1.8 to 4.3. Furthermore, the invention provides an image forming method for carrying out X-ray exposure using the photothermographic material and an X-ray intensifying screen. The present invention gives a high-sensitivity and clear image that has a low degree of haze of the film after a thermal developing process.

摘要:
A photothermographic imaging material including a support; an image forming layer containing an organic silver salt, a photosensitive silver halide, a binder and a silver ion reducing agent, the image forming layer being provided on the support; and a cyan coloring leuco dye. The photosensitive silver halide contains silver halide grains having a mean particle size of 10 to 50 nm, and the silver ion reducing agent is a compound represented by the following Formula (A-3). 1
摘要:
Disclosed is a silver halide photographic light-sensitive material comprising at least one silver halide emulsion layer on a support, wherein 40 mol % or more of silver halide contained in the silver halide emulsion layer is silver bromide and the silver halide contains 1null10null6 mole or more per mole of silver of a metal complex containing one or more cyanide ligands, and the silver halide photographic light-sensitive material has a characteristic curve drawn in orthogonal coordinates of logarithm of light exposure (x-axis) and optical density (y-axis) using equal unit lengths for the both axes, on which gamma is 4.0 or more for the optical density range of 0.1-1.5. There is provided a silver halide photographic light-sensitive material showing high contrast and high sensitivity.
摘要:
Thermally developable materials that comprise a support have at least two backside layers. One of these layers can be a protective layer comprising a film-forming polymer. The materials also includes a non-imaging backside conductive layer comprising non-acicular metal antimonate particles in a mixture of two or more polymers that includes a first polymer serving to promote adhesion of the backside conductive layer directly to the support or other layers, and a second polymer that is different than and forms a single phase mixture with the first polymer.
摘要:
Disclosed are sources and methods for delivering a radioactive dose to a site in a body lumen. The sources are preferably mounted on a balloon or other expandable or deployable mechanical structure. The source and methods enable delivery of a clinically significant dose of radiation into a vessel wall in a relatively short time while using a relatively low activity. The sources also enable delivery of a substantially uniform dose into the vessel wall, whether or not such delivery is through the wall of a stent.
