  • Publication number: 20190328238
    Abstract: A computer-implemented method for classifying a tissue type within a tissue sample using laser-stimulated thermal imaging (LSTI) is disclosed. The method includes obtaining a first thermal image of the tissue sample, introducing at least one thermal stimulation into at least one thermal stimulation volume within the tissue sample, obtaining a second thermal image of the tissue sample, creating a spatial temperature plot based on the first and second thermal images, determining at least one thermal diffusion parameter from the spatial temperature plot, and classifying each tissue type adjacent to each of the at least one thermal stimulation volumes based on the at least one thermal diffusion parameter.
