    摘要: The invention relates to systems and methods for tomographic imaging of a subject comprising diffuse media by converting measurements of electromagnetic radiation, e.g., fluorescent light, obtained in free space exterior to the subject into data that would be measured if the subject were surrounded by an infinite and homogeneous diffusive medium, e.g., a medium with optical properties equal to the average optical properties of the subject. After applying a transformation to convert measurements to virtually-matched values, propagation of light is simulated from the index-matched surface to a set of virtual detectors exterior to the subject and arranged in a geometrically advantageous fashion, for example, in a planar array, thereby facilitating the use of fast reconstruction techniques.

    摘要: The invention facilitates transport of an immobilized, anesthetized small animal across multiple single-modality or multiple-modality imaging workstations at the same or different physical locations without loss of subject positional information. The animal holder is compatible with preclinical animal imaging stations such as micro-CT, micro-MR, micro-PET, micro-SPECT, and FMT. The animal holder is configured to be accommodated by (for example, fit within) individual imaging chambers of such instruments and is fabricated from materials that are compliant with all of the imaging modalities used. In certain embodiments, an integrated set of fiducial marker wells accommodates the dispensing of markers that are picked up by several modalities simultaneously in multiple planes. The fiducial markers then are aligned in standard image processing or image analysis software with simple image translation and rotation operations, without the need for more advanced scaling, distortion or other operations. The animal holder optionally also includes a system for providing the animal with inhalation anesthesia, for example, isoflurane, and is designed to fit into identical receptacles inside or outside the imaging workstation(s) that provide heating to minimize or prevent animal hypothermia.

    摘要: The invention relates to systems and methods for tomographic imaging in diffuse media employing a fast reconstruction technique. A hybrid Fourier approach is presented that enables the fast tomographic reconstruction of large datasets. In certain embodiments, the invention features methods of in vivo fluorescence molecular tomographic (FMT) reconstruction of signals, reporters and/or agents (i.e., contrast agents or probes) in a diffusive medium (e.g., a mammalian subject). The method preserves the three-dimensional fluorophore distribution and quantitative nature of the FMT approach while substantially accelerating its computation speed, allowing FMT imaging of larger anatomies.
