  • Patent number: 9008758
    Abstract: The invention described herein provides systems and methods for multi-modal imaging with light and a second form of imaging. Light imaging involves the capture of low intensity light from a light-emitting object. A camera obtains a two-dimensional spatial distribution of the light emitted from the surface of the subject. Software operated by a computer in communication with the camera may then convert two-dimensional spatial distribution data from one or more images into a three-dimensional spatial representation. The second imaging mode may include any imaging technique that compliments light imaging. Examples include magnetic resonance imaging (MRI) and computer topography (CT). An object handling system moves the object to be imaged between the light imaging system and the second imaging system, and is configured to interface with each system.

  • Patent number: 8279334
    Abstract: The present invention integrates a structured light source into an imaging system for reconstructing surface topography of an object being imaged. The structured light source includes a mechanism for transmitting a set of lines onto the object from an angle. The lines are displaced, or phase shifted relative to a stage, when they encounter an object with finite height, such as a mouse. This phase shift provides structured light information for the object. A camera captures the structured light information. Using software that employs a structured light analysis, surface topography data for the object is determined from the phase shift of the lines.

  • Patent number: 7813782
    Abstract: The invention described herein provides systems and methods for handling objects within an imaging system, such as a multi-modal imaging system. An object handling system operates to position an object to be imaged in an interior cavity of a light imaging system, and also moves the object to be imaged between the light imaging system and a second imaging system. The object handling system can include components such as a stage that supports the object, a manipulator configured to move the stage between the interior and exterior of the light imaging system and a light seal configured to interface with a light seal on an exterior wall of the light imaging system.

  • Patent number: 7474398
    Abstract: A fluorescence illumination system is provided for use with an imaging apparatus that defines a light-tight imaging compartment. The fluorescence illumination system includes a trans-illumination component configured to direct excitation light into a first surface of the specimen wherein diffused light emanates from a second surface thereof for receipt through the view port to acquire fluorescence data of the specimen. Further, the fluorescence illumination system includes an epi-illumination component configured to direct excitation light onto a third surface of the specimen wherein the diffused light exits the third surface thereof for receipt through the view port to acquire fluorescence data of the specimen.

  • Patent number: 7474399
    Abstract: A dual illumination system is disclosed for use with an imaging apparatus. The imaging apparatus defines a light-tight imaging compartment with an interior wall having a view port extending into the imaging compartment. This view port enables data acquisition of a biological specimen contained in the imaging compartment. The dual illumination system includes a first illumination assembly configured to direct structured light onto a first side of the specimen to enable structured light and surface topography measurements thereof. A second illumination assembly then directs light at the specimen wherein diffused fluorescent light emanates from a surface thereof for receipt through the view port to acquire fluorescence data of the specimen. The combination of structured light imaging and fluorescence imaging enables 3D diffuse tomographic reconstructions of fluorescent probe location and concentration.

  • Patent number: 7466418
    Abstract: A macroscopic fluorescence illumination assembly is provided for use with an imaging apparatus with a light-tight imaging compartment. The imaging apparatus includes an interior wall defining a view port extending into the imaging compartment to enable viewing of a specimen contained therein. The illumination assembly includes a specimen support surface facing toward the view port of the imaging apparatus. The support surface defines a window portion that enables the passage of light there through. The window portion is selectively sized and dimensioned such that the specimen, when supported atop the support surface, can be positioned and seated over the window portion in a manner forming a light-tight seal substantially there between.

  • Publication number: 20070200058
    Abstract: Described herein is a phantom device that simplifies usage, testing, and development of light imaging systems. The phantom device includes a body and a fluorescent light source internal to the body. The body comprises an optical material designed to at least partially resemble the optical behavior of mammalian tissue. The phantom device has many uses. One use of the phantom device permits testing of tomography software in the imaging system, such as software configured for 3D reconstruction of the fluorescent light source. Another use tests spectral unmixing software in the imaging system. The phantom device also allows a user to compare trans- and epi-fluorescent illumination imaging results.
