摘要:
A soda-lime-silica based privacy glass, having a visible transmission (Lta) of no greater than 25% and an infrared (IR) transmission no greater than 25%, includes the following colorants in addition to the base glass: total iron (expressed as Fe2O3): 0.1 to 1.0% cobalt oxide (e.g., Co3O4): 0 to 1,000 ppm sulfides (S2−): 0.0001 to 0.10%. In certain other embodiments the visible transmission may be higher, but low IR transmission is still realized.

摘要:
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.

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.

Systems and methods are provided for taking images of a sample. The sample is placed in an imaging box comprising a moveable stage that allows images of the sample to be taken from various positions and angles within the imaging box. The images are taken by a camera and sent to a processor. Structured light images obtained from one or more views within the imaging box may be used to build a structured light representations of the sample.

An imaging box assembly is provided for capturing an image of a sample. The imaging box assembly includes a body having an interior cavity for receiving the sample, and having a front portion defining an opening into the cavity. The body further includes a view port enabling viewing of the sample contained in the interior cavity. A door is mounted to the body that is movable between an opened condition, enabling access to the interior cavity through the cavity opening, and a closed condition, positioning a door rear portion substantially adjacent the body front portion to prevent access through the cavity opening. The box assembly further includes a stage disposed in the cavity interior that supports the sample, and a gas manifold device in communication with the interior cavity. The manifold is configured to supply a gas to interior cavity proximate the sample. A tube transports the gas from outside the imaging box to the gas manifold device.

The invention describes systems and methods to obtain and present imaging data in absolute units. The systems and methods convert relative image data produced by a camera to absolute light intensity data using a compensation factor. The compensation factor accommodates for hardware and specific imaging conditions in the imaging system that variably affect camera output. The present invention determines the compensation factor based on assessing the output of the camera against a known light source for a specific set of imaging conditions in the imaging system. The compensation factor is then stored in memory corresponding to the specific set of imaging conditions. Upon subsequent imaging with the set of imaging conditions, the corresponding compensation factor is called from memory and applied to the camera output. A compensation factor may be determined and stored for each hardware state and imaging condition available to the imaging system.
摘要:
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.
