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.

摘要： 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.

摘要： An integrated microtomography and optical imaging system includes a rotating table that supports an imaging object, an optical stage, and separate optical and microtomography imaging systems. The table rotates the imaging object about a vertical axis running therethrough to a plurality of different rotational positions during a combined microtomography and optical imaging process. The optical stage can be a trans-illumination, epi-illumination or bioluminescent stage. The optical imaging system includes a camera positioned vertically above the imaging object. The microtomography system includes an x-ray source positioned horizontally with respect to the imaging object. Optical and x-ray images are both obtained while the imaging object remains in place on the rotating table. The stage and table are included within an imaging chamber, and all components are included within a portable cabinet. Multiple imaging objects can be imaged simultaneously, and side mirrors can provide side views of the object to the overhead camera.

摘要： 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.
