We developed an approach to quantify intra-tumoral metabolic heterogeneity of in vivo tumor models by leveraging a computationally designed multi-scale microscope and a suite of exogenous fluorescent contrast agents to provide functional and structural information.
Commercial imaging systems such as mobile phones are suitable for fluorescence detection of in vivo and ex vivo tissue samples. To leverage this potential, a uniform plane of excitation light is necessary to make quantitative measurements of regions within an image. We have developed a computational model to simulate the illumination of an arbitrary number of sources. Using a pattern search algorithm, the position of these sources can be determined to generate a uniform plane of excitation light. Initial studies demonstrate that 4 fiber optic sources can be used to generate uniform illumination for biopsy samples with different geometries.
