  • Patent number: 7555334
    Abstract: Disclosed are methods and apparatus for collecting light emitted from an animal, where a luminescent reporter has been injected into the animal is disclosed. The apparatus includes a chamber for receiving the animal, wherein the chamber is light tight preventing a substantial portion of light emitted from the animal from escaping the chamber when the chamber is closed and the animal is inside the chamber and a light monitoring device for collecting light from different portions of the animal when the animal is inside the closed chamber. The light monitoring device is arranged to collect light over substantially the entire surface area of the body and head of the animal, and the light monitoring device generates a quantified value based on the light collected from the animal. The animal does not have to be under anesthesia.

  • Patent number: 7555332
    Abstract: Described herein are systems and methods for obtaining a three-dimensional (3D) representation of the distribution of fluorescent probes inside a sample, such as a mammal. Using a) fluorescent light emission data from one or more images, b) a surface representation of the mammal, and c) computer-implemented photon propagation models, the systems and methods produce a 3D representation of the fluorescent probe distribution in the mammal. The distribution may indicate—in 3D—the location, size, and/or brightness or concentration of one or more fluorescent probes in the mammal.

  • Patent number: 7403812
    Abstract: A method of investigating the location and size of a light-emitting source in a subject is disclosed. In practicing the method, one first obtains a light intensity profile by measuring, from a first perspective with a photodetector device, photons which (i) originate from the light-emitting source, (ii) travel through turbid biological tissue of the subject, and (iii) are emitted from a first surface region of interest of the subject. The light-intensity profile is matched against with a parameter-based biophotonic function, to estimate function parameters such as depth and size. The parameters so determined are refined using data other than the first measured light intensity profile, to obtain an approximate depth and size of the source in the subject. Also disclosed is an apparatus for carrying out the method.

  • Patent number: 7298415
    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: 7190991
    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: 6754008
    Abstract: Disclosed is an improved lens system for low light applications. This improved low light lens system is designed for any suitable low light application, such as the above described biological imaging application. In one embodiment, a finite conjugate lens system is disclosed. The lens system includes, in order from a camera side to an object side, a first lens group and a second lens group. The first and second lens groups are adapted so that when light is passed from the object side to the image side, a substantially sized region of collimated light is formed between the first and second lens group. Preferably, the first and second lens groups are adapted to demagnify an object at the object side.

  • Publication number: 20040021771
    Abstract: The present invention provides systems and methods for obtaining a three-dimensional (3D) representation of one or more light sources inside a sample, such as a mammal. Mammalian tissue is a turbid medium, meaning that photons are both absorbed and scattered as they propagate through tissue. In the case where scattering is large compared with absorption, such as red to near-infrared light passing through tissue, the transport of light within the sample is described by diffusion theory. Using imaging data and computer-implemented photon diffusion models, embodiments of the present invention produce a 3D representation of the light sources inside a sample, such as a 3D location, size, and brightness of such light sources.
