  • Publication number: 20140128730
    Abstract: An image of an object is synergistically reconstructed using two or multiple imaging modalities. A first reconstructed image, showing structural information of the object is produced using a first imaging modality. The first reconstructed image is segmented, and known optical properties of the object are then mapped to the first reconstructed image. Optical signal emissions from the object are detected and registered with the first reconstructed image. A second reconstructed image volume is then produced using a second imaging modality, based on the mapped optical properties after registration between the first image and the data from the second modality. The second reconstructed image depicts some optical property, such as a bioluminescent source distribution, or optical properties, such as, attenuation and scattering properties, of the object.

  • Patent number: 7885438
    Abstract: A method for automated analysis of textural differences present on an image volume. The image volume includes a plurality of volume elements, and each volume element has a gray level. The method includes defining a volume of interest (VOI); performing texture measures within the VOI; and classifying the VOI as belonging to a tissue pathology class based upon the texture measures. Computer readable media encoded with computer readable instructions for carrying out these functions. An apparatus that includes an image input adapted to receive a diagnostic medical image. The image includes a plurality of pixels, and each pixel has a particular gray level. The apparatus also includes a display for displaying a graphical user interface and the received image; and a processor adapted to perform texture measures on one or more groups of pixels within the image and classify each group of pixels to a tissue pathology class based upon the textures measures.

  • Publication number: 20090257723
    Abstract: An elongate imaging fiber bundle may include a plurality of elongate optical fibers coherently arranged in the bundle, the plurality including peripheral fibers at a periphery of the bundle and deep fibers deep to the peripheral fibers, and a coating surrounding the plurality of fibers. An exposed length of the bundle, intermediate the bundle's proximal and distal ends, may be chemically etched to be denuded of the coating, and peripheral fibers are so severed as to permit injection of light into the peripheral fibers at the exposed length. A fiberscope may include a fiber bundle having an exposed length that is denuded of the coating, and peripheral fibers are so severed in the exposed length as to permit injection of light into the peripheral fibers at the exposed length, and a light source so positioned with respect to the exposed length of the bundle as to inject light into the peripheral fibers at the exposed length.
