Abstract: Systems and methods for discriminating between malignant and benign pigmented skin lesions based on optical analysis using spatial distribution maps, morphological parameters, and additional diagnostic parameters derived from images of tissue lesions. A handheld optical transfer diagnosis device is disclosed capable of capturing a series of reflectance images of a skin lesion at a variety of angles of illumination and observation.

Abstract: 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 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 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 morphology parameter and a weight to a logarithm of each morphology parameter.

Abstract: 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.

Abstract: The present invention relates to a method and an arrangement for the determination of the optical properties of a multi-layered tissue. More specifically, the invention relates to a method for the detection and characterization of tumors in a tissue.
