    摘要: The invention relates to topographic construction that combines photographic and structured light information. The dual modality construction acquires structured light information for an object and photographic images from multiple views about the object. Topographic construction then processes the structured light information and photographic data in the multiple images to generate a surface representation of the object in each modality. The photographic and structured light surface representations are then combined to output a dual modality surface topography.

    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.

    摘要: Described herein are systems and methods for spectral unmixing of in vivo light data. The spectral unmixing separates image data according to spectra from multiple internal light sources in an effort to isolate one or more spectrum of interest. The spectral unmixing obtains images with a combination of different and known excitation and emission limits. The spectral unmixing then uses an iterative solution process to separate spectra for the multiple fluorescent light sources, and provides a spectrum and/or a spatial distribution map for at least one of the internal light sources.

    摘要: Optical tomography systems that provide light of multiple distinct wavelengths from a plurality of sources are described. The systems direct light into mammalian tissue, and light from the mammalian tissue is collected at a plurality of reception points. Collected light from each reception point is separated according to its wavelength, and received by a photodetector to produce path attenuation signals representing attenuation along paths between the source locations and the reception points. An image construction system generates a tomographic image of the mammalian tissue from the path attenuation signals. One embodiment of an optical imaging system includes an optical coherence tomography-near infrared probe. The systems and methods may utilize a spectral derivative approach that provides insensitivity to the boundary and boundary artifacts in the signal, thereby improving the quality of the reconstructed images.

The method of preparing a macromolecular conjugated ligand comprises: (a) providing a compound of formula (I) wherein R, A, and Pg are as defined herein, (b) reacting the compound of formula (I) with a macromolecular compound (e.g., dendrimer) in an organic solvent medium which is substantially free of water to obtain a macromolecular conjugated compound, and (c) removing the carboxyl-protecting groups to obtain a carboxyl-deprotected macromolecular conjugated compound. The metal complex can be prepared by reacting the carboxyl-deprotected macromolecular conjugated compound with an ion (e.g., Gd(III)). Also disclosed are two carboxyl-protected 1B4M-DTPA intermediate compounds.
