  • Patent number: 10867387
    Abstract: A method of locating content portion(s) of an image includes automatically determining a pixel threshold value; comparing the threshold value to the image to determine background and content sets of the pixels; determining boundaries between the background and content sets; determining the content portions using the determined boundaries; and determining bounding boxes for the content portions. A computed-radiography scanner includes an imager; a transport configured to operatively arrange a plurality of plates with respect to the imager so that a single image of the plates can be captured; and a processor configured to automatically locate the content portion(s) in the single image. A locating method includes automatically determining the pixel threshold value; determining the boundaries between portions delimited by the pixel threshold value; determining the content portions using the boundaries; and determining the bounding boxes.

  • Patent number: 7304321
    Abstract: A storage phosphor cassette for use in recording radiographic images of elongated objects. The cassette comprises a shell and a single storage phosphor plate. The shell includes first and second opposite open ends. The single storage phosphor plate is housed within the shell and is adapted to be at least partially removable from the shell through the first and second open ends. A radiation image of the elongate object can be read by extracting a first portion of the single plate through one of the two opposing ends of the cassette and scanning the first portion of the single storage phosphor plate to obtain a first partial image, and then extracting a second portion of the single plate through the other of the two opposing ends of the cassette and scanning the second portion of the single storage phosphor plate to obtain a second partial image. The first and second partial images can be combined to form the image of the elongate object.

  • Patent number: 7250622
    Abstract: After a housing of a cassette is opened by a suction cup, then a stimulable phosphor sheet is removed from the cassette by a shiftable roller and then fed in an auxiliary scanning direction by a feed mechanism. While being fed in the auxiliary scanning direction, the stimulable phosphor sheet is irradiated with a laser beam emitted from a stimulating optical system. Light emitted from the stimulable phosphor sheet upon exposure to the laser beam is guided through a light guide to a photoelectric transducer. After the recorded radiation image information is read from the stimulable phosphor sheet, the stimulable phosphor sheet is stored back into the cassette, and erasing light from erasing light sources is applied to the stimulable phosphor sheet in the cassette to erase remaining radiation image information from the stimulable phosphor sheet.

  • Patent number: 7220980
    Abstract: A substantially rectangular insertion opening is formed on the upper surface of the housing of the radiation image reading device. An L-shaped projecting portion which runs from the back side periphery to the right side periphery of the insertion opening is integrally formed with the housing and the projecting portion protrudes above the upper surface of the housing, and the top surface of the projecting portion is higher than the upper surface of the housing. When the cassette is inserted into the insertion opening, if the cassette is allowed to come in contact with the side surface of the projecting portion, positioning of the cassette at the insertion opening is simpler. As a result, quicker and easier insertion of the cassette into the insertion opening becomes possible.

    Abstract: An image reading apparatus includes a casing having a side panel which has a cassette loading slot defined therein for loading a cassette therein. A stimulable phosphor sheet stored in the cassette loaded in the cassette loading slot is removed from the cassette and fed vertically downwardly along a first vertical feed path. Radiation image information recorded in the stimulable phosphor sheet is read by a reader. Thereafter, the stimulable phosphor sheet is stored back into the cassette, which is then delivered toward a cassette unloading slot by a sliding displacement mechanism.
