Abstract:
A method for mapping temperature changes in tissue comprising:receiving an image of tissue comprised of multiple pixels;segregating said image into groups of pixels, each said group of pixels having a corresponding set of descriptors derived from said pixels in said corresponding group of pixels;establishing a baseline for at least one of each group of pixels and said corresponding set of descriptors, said baseline corresponding to initial conditions of the tissue as a learning set;measuring a differential between said set of descriptors for a group of pixels which correspond to new pixels within a group of pixels and said baseline for said set of descriptors for said group of pixels;correlating said measured differential to a temperature change for the tissue corresponding to said group of pixels; andoverlaying an indication of temperature over the tissue image in response to said correlated temperature change indicating a change in temperature range for the tissue.
