摘要:
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.

A concept for improving signal to background for images obtained in a scattering medium such as smoke and fog has been described. This concept can be used to develop instrumentation potentially useful for firefighters or other rescue workers as well as law enforcement and military personnel. Additional applications are use of this technique for operation of vehicles in smoke or fog. This concept can be utilized in conjunction with a variety of other measurement techniques but is most simply envisioned for use with time resolved ballistic and quasi-ballistic imaging.

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 moveable stage disposed in the cavity interior that supports the sample. The moveable stage is adapted to selectively position the sample at a selected one of a plurality of positions relative to the view hole.

The present invention provides a computer system and user interface that allows a user to readily view and analyze two-dimensional and three-dimensional in vivo images and imaging data. The user interface is well-suited for one or more of the following actions pertinent to in vivo light imaging: investigation and control of three-dimensional imaging data and reconstruction algorithms; control of topographic reconstruction algorithms; tomographic spectral imaging and analysis; and comparison of two-dimensional or three-dimensional imaging data obtained at different times.
