Abstract

Systems, apparatuses, and methods are described for 3D luminescence imaging, by identifying a preferred optical pair and optimizing a scanned image using the preferred optical pair. An optimal filter pair may be selected from a list of two or more optical filters. An acceptable threshold of information may be obtained using a subset of the list of two or more optical filters (e.g., an optimal filter pair). An imaging device may be configured with the optimal filter pair to produce a pair of luminescence images of a target sample. In addition, luminescence images may be pre-processed to reduce the time-cost of conventional processing techniques of luminescence images. One or more computing devices may generate initial prior data based on a pair of luminescence images. An output may include one or more output luminescent sources that have been refined and/or optimized from the initial prior data.

generating one or more volume sub-regions by, for each volume sub-region, of the one or more volume sub-region, corresponding to an image segment of the one or more image segments:
generating one or more volume test-regions, wherein each of the one or more volume test-regions comprise one or more voxels assigned one or more radiation test-values, and wherein the one or more radiation test-values are determined based on the bioluminescent source, the volume of biological material, and the one or more optical filters;
generating, based on the one or more radiation test-values assigned to the one or more voxels and the one or more optical filters, one or more test images;
generating, based on the one or more test images, image test-segments;
determining correlation values between the image test-segments and the image segment; and
selecting, based on the correlation values of the image test-segments, a volume test-region as the volume sub-region;

determining, based on the one or more volume sub-regions, an output volume region comprising output voxels, wherein one or more output radiation values are assigned to each of the output voxels; and
