    摘要： A blue-sensitive radiographic silver halide film comprises a silver halide emulsion layer comprising predominantly tabular silver halide grains that have an aspect ratio of at least 15, a grain thickness of at least 0.1 &mgr;m, and comprise at least 90 mol % bromide and up to 4 mol % iodide, based on total silver halide. Substantially all of the iodide is present in an internal localized portion of the tabular silver halide grains that excludes the surface of the grains. The tabular silver halide grains are dispersed in a hydrophilic polymeric vehicle mixture comprising at least 0.5% of oxidized gelatin, based on the total dry weight of the polymeric vehicle mixture in the emulsion layer. The tabular silver halide grains are spectrally sensitized using a combination of spectral sensitizing dyes to provide increased speed and reduced dye stain. The dyes have maximum J-aggregate absorptions on the tabular silver halide grains of from about 380 to about 500 nm, wherein the maximum J-aggregate absorption of one spectral sensitizing dye is from about 20 to about 50 nm lower in wavelength than the maximum J-aggregate absorption of the second spectral sensitizing dye.

    摘要： Portal radiographic elements and a process of confirming the targeting of a beam of X-radiation of from 4 to 25 MVp using the portal radiographic elements are disclosed. The X-radiation is directed at a shield containing a port to create a beam. The beam is directed at a selected anatomical feature of a patient over a period of at least 30 seconds. The portion of the beam that passes through the patient impinges on a metal screen, causing it to emit electrons, and the electrons impinge upon a fluorescent screen, causing it to emit light that exposes a portal verification radiographic element to create a latent image in light-sensitized silver halide grains. A processor is employed to convert the latent image to a viewable silver image from which intended targeting of the X-radiation beam can be verified. The processor relies on attenuation of an infrared beam of a wavelength from 850 to 1100 nm by the radiographic element for activation, and at least one of the hydrophilic colloid layers of the radiographic element contains desensitized silver halide grains to increase the specular density of the radiographic element in the wavelength range of infrared sensors that control the processor.
