  • Patent number: 7622730
    Abstract: A radiation image formation read out method for a storage phosphor screen. A phosphor screen is exposed to a first stimulating radiation from a first side of the screen to release a first stimulated radiation in the pattern of the stored image. The first stimulating radiation is at a first power level, a first scan speed, and a first set of scanning parameters and is photoelectrically detected. The storage phosphor screen is again exposed to a second stimulating radiation from the first side of the screen to release a second stimulated radiation in the pattern of the stored image. The first stimulated radiation has a greater amount of high spatial frequency image data than the second stimulated radiation. The second stimulating radiation is at a second power level, a second scan speed, and a second set of scanning parameters.

  • Publication number: 20040021769
    Abstract: A method for detecting artifacts produced during film scanning in a scanning device, the method includes the steps of (a) providing film having a plurality of frames with an area of substantially constant density; (b) scanning the area of substantially constant density by the scanning device; (c) generating a profile consisting of the average of substantially all pixels at substantially the same location in the area of substantially constant density; and (d) detecting an artifact based on comparing the profile to a first threshold.

  • Patent number: 6620562
    Abstract: The present invention is directed to a method of scanning silver-halide-containing color photographic and photothermographic film. In particular, the present invention comprises a photographic element comprising at least one infrared imaging dye-forming agent in a blue-sensitive color layer of the element, thereby forming at least one image record in the infrared region of the imagewise exposed and developed element. This expedient leads to the formation of high quality images when scanning photographic elements in which the silver halide, metallic silver, and/or any organic silver salts have not been removed.

  • Patent number: 5627381
    Abstract: A storage phosphor imaging system includes a scanner for scanning a storage phosphor storing an x-ray image to produce an x-ray light image, a converter for converting the x-ray light image into a digital x-ray image signal having a range of code values, and a storage phosphor erase light assembly for erasing the storage phosphor of substantially all residual image. Apparatus for controlling the erase light assembly includes a digital image processor for determining the maximum code value of a digital x-ray image signal which is produced from an x-ray image stored in a storage phosphor to be erased; and a controller for controlling the time of actuation of the erase light assembly as a function of the determined maximum code value.

  • Patent number: 4999505
    Abstract: A radiation image storage panel includes a layer of transparent stimulable phosphor, a filter layer for strongly absorbing stimulating radiation and transmitting emitted radiation, and a radiation diffusing layer. The filter layer absorbs the beam of stimulating radiation so that an image recorded in the storage panel is not blurred by scattered stimulating radiation during readout, and the diffusing layer increases the escape efficiency of the emitted light from the storage panel.

  • Patent number: 4991918
    Abstract: Light collectors formed by rolling one edge of a sheet of transparent thermoplastic material into an annular configuration, while keeping an opposite edge flat suffer from light collection inefficiency caused by local stretching and thus thinning of the sheet near the annular end, thereby increasing the number of internal reflections experienced by a light ray. This problem is solved by making a light collector that is uniform in thickness, or thicker toward the annular end.
