Method and system for non-invasive temperature mapping of tissue |
摘要 |
A method and system for mapping temperature from image data. The method includes the steps of: receiving an image of tissue comprised of multiple pixels, segregating the image into groups of pixels (104), each group of pixels having a set of descriptors (106), establishing a baseline set of descriptors corresponding to initial conditions of the imaged tissue (108), measuring a differential in the set of descriptors for a group of pixels (114), the differential corresponding to a change in pixel values for the group of pixels, correlating said measured differential to a temperature change for the tissue corresponding to the group of pixels (118-124), and overlaying an indication of temperature over the tissue image in response to said correlated temperature change indicating a change in temperature range for the tissue (130-132). The system includes a digital processor implementing a neural network for evaluating a set of descriptors against baseline values learned by the neural network form the initial conditions of the tissue.
