Presented herein are systems and methods for tomographic imaging of a region of interest in a subject using short-wave infrared light to provide for accurate reconstruction of absorption maps within the region of interest. The reconstructed absorption maps are representations of the spatial variation in tissue absorption within the region of interest. The reconstructed absorption maps can themselves be used to analyze anatomical properties and biological processes within the region of interest, and / or be used as input information about anatomical properties in order to facilitate data processing used to obtain images of the region of interest via other imaging modalities. For example, the reconstructed absorption maps may be incorporated into forward models that are used in tomographic reconstruction processing in fluorescence and other contrast-based tomographic imaging modalities. Incorporating reconstructed absorption maps into other tomographic reconstruction processing algorithmsin the manner improves the accuracy of the resultant reconstructions.
Description
technical field [0001] The present invention generally relates to methods and systems for tomography. More specifically, in certain embodiments, the present invention relates to tomography using shortwave infrared (SWIR) radiation. Background technique [0002] In vivo imaging of small mammals is performed by numerous researchers in fields as diverse as oncology, infectious disease, and drug discovery. A wide variety of techniques are involved in in vivo imaging of mammals, such as bioluminescence, fluorescence, tomography, and multimodal imaging. [0003] Many imaging modalities are tomographic methods. Tomography is based on the detection of light transmitted through or emitted from a sample in order to obtain an image of or infer the optical properties of the sample under study. For example, tomography can be used to reconstruct tissue uptake maps within a region of interest of a subject under study. In other applications, tomography is used to generate a map of the s...
