  • Patent number: 8167794
    Abstract: An endoscope system is disclosed for detecting fluorescent light emitted in the near-infrared region by a plurality of fluorescent labeling materials introduced into a living tissue. An illumination system generates illumination light in the wavelength range 600 nm-2000 nm which serves as excitation light for the plurality of fluorescent labeling materials, and a detection system that can separately detect different ones of the plurality of fluorescent light emissions that are emitted at different wavelengths from among the plurality of fluorescent labeling materials is provided. The endoscope system may include a conventional-type endoscope having an insertion section, or a capsule endoscope that wirelessly transmits image data. By superimposing the image data obtained using reflected light in the visible region and fluorescent light emitted by the fluorescent labeling materials, improved diagnostic capabilities are provided.

  • Patent number: 8064677
    Abstract: A system and method are provided for the measurement and display of attributes of an object of interest in a medical image. An object of interest is identified, such as a lesion or cluster of lesions in a breast area on a mammography image. At least one attribute of the lesion is then automatically measured, such as the area of the lesion, the width and height of a cluster of lesions, the number of lesions in a cluster, or the distance from one or more lesions to an anatomical feature such as the nipple, skin line or chest wall. The measurements are then displayed to a user, for example by displaying the measurements on the mammography image. Additionally, anatomical zones, such as standard, quadrant and clock zones of the breast area may be determined and displayed on the mammography image or diagram to display the location of the lesion as it corresponds to the zones.

  • Patent number: 7961213
    Abstract: An image pickup apparatus includes an objective optical system, an image pickup element having a surface at an image formed by the objective optical system, and an etalon positioned between the objective optical system and the surface of the image pickup element. The etalon includes a gap, an optical path length of which is controllable for scanning the wavelengths transmitted by the etalon to thereby select the wavelengths that reach the surface. An optical filter is positioned between the objective optical system and the surface and has a first wavelength range over which incident light is reflected, a second wavelength range over which incident light is transmitted, and a boundary wavelength range that is bounded by the first and second wavelength ranges. The boundary wavelength range lies entirely within the wavelength range the peak transmission of the etalon can be scanned. A method of calibrating the etalon is also disclosed.

  • Publication number: 20110123074
    Abstract: A system and method are provided for altering the appearance of an artificial object in a medical image. An artificial object is first identified in the medical image, such as identifying a breast implant in a mammography image. The prominence of the artificial object is then reduced, for example by suppressing the brightness or masking the artificial object out altogether. The resulting medical image with the altered artificial object is then displayed to a user so that the medical image can be more accurately analyzed without requiring the user to adjust the image on his or her own.

  • Publication number: 20110123086
    Abstract: A system and method is provided for enhancing a region of interest in a medical image to improve its visibility. A region of interest is first identified in the medical image, such as identifying a breast region in a mammography image. The identified region of interest is then enhanced using an image processing technique, for example by adjusting the intensity or contrast, or by performing edge enhancement. Other regions of the medical image outside the region of interest remain unaltered, or may be diminished, such that the clarity of the region of interest is improved in comparison with the other regions of the medical image. A user viewing the enhanced image is less distracted by the non-enhanced regions and is not required to adjust the image on his or her own. The user can more quickly and effectively review the medical image to identify abnormalities and diagnose disease.

  • Publication number: 20110123075
    Abstract: A system and method is provided for automatically detecting and marking a region of interest in a medical image. A region of interest is first identified in the medical image, such as a nipple of a breast region in a mammography image. The identified nipple is then marked with a digital indicator, such as a bright circle, so that a user viewing the image can easily identify the nipple. The digital indicator can be temporarily removed so that no portion of the region of interest is obscured by the digital indicator. A region of interest corresponding to another anatomical feature may also be marked, such as a pectoral muscle, which may be marked by placing a digital outline around the border of the pectoral muscle. A user viewing the medical image with the digital indicators can easily identify the marked regions of interest.
