    摘要： In an embodiment of the present disclosure, an optical method for determining morphological parameters and physiological properties of tissue is presented. The method includes using reflectance measurements from a tissue area for a plurality of wavelengths, using a bio-optical model, using radiative transfer modeling and using a non-linear inversion procedure. The method further includes systematically varying values of the morphological parameters and physiological properties of the tissue and simultaneously varying the inherent optical properties, which are linked to the morphological parameters and the physiological properties of the tissue, until the non-linear inversion procedure returns values for the morphological parameters and the physiological properties of the tissue such that an agreement between the reflectance measurements and reflectances computed by the radiative transfer model, based on the returned morphological parameters and the physiological properties of the tissue values and corresponding inherent optical properties values, reach a predetermined level of accuracy.

    摘要： An embodiment of the present invention includes a method for discriminating between benign and malignant tissue lesions. The method includes the steps of using a plurality of maps of physiology and morphology parameters generated from reflectance measurements and pure morphology parameters generated from reflectance measurements. The method also includes calculating entropies and cross entropies of the plurality of maps, and calculating a plurality of pure morphology parameters. Further, the method includes assigning a weight to each entropy and a weight to a logarithm of each entropy, a weight to each cross entropy and a weight to a logarithm of each cross entropy, and a weight to each pure morphology parameter and a weight to a logarithm of each pure morphoiogy parameter. The method further includes computing a diagnostic index, defining a cost function, defining a proper threshold value for a diagnostic index and solving an optimization problem to determine a set of weights from the assigned weights to maximize specificity for 100% sensitivity. Further, the method uses calculations, the cost function and the diagnostic index to determine whether the tissue lesion is benign or malignant.
