Abstract: Multispectral digitized images are provided by utilizing 2 or more spectral bands, providing images and information regarding a pigmented or other differentiated tissue sample at differing depths. The images are transformed to enhance morphological patterns characteristic of melanoma, such as the statistical properties of the pigment network, image texture or homogeneity, and the lesion reflectance, in order to provide information about lesion morphology at different depths. The images can also be processed and transformed to extract features such as blood volume saturation, oxygen saturation, or other characteristics that can be identified based on differential reflectance or absorption of light.

Abstract: Among other things, on a two-dimensional electronic display are shown simultaneously: (a) at least a partial body view of a surface of the human model on which a location of a skin lesion on a corresponding real human has been indicated, and (b) an image of the lesion area that corresponds to the partial body view of the human model.

Abstract: Skin disorders such as, for example, atopic dermatitis, dyshidrosis, eczema, lichen planus, psoriasis, and vitiligo, are treated by applying high doses of ultraviolet light to diseased regions of a patients skin. The dosage employed exceeds 1 MED, an MED being determined for the particular patient being treated, and may range from about 1 MED to about 20 MED or higher. The ultraviolet light has a wavelength within the range of between about 295 nanometers to about 320 nanometers and preferably is between about 300 nanometers and about 310 nanometers. High doses of ultraviolet light are restricted to diseased tissue areas so as to avoid risk of detrimental side affects in healthy skin, which is more susceptible to damage from UV light. Cooling the skin prior to and/or while exposing the skin to the UV light can be used to minimize tissue damage resulting from exposure to the UV light. Higher doses of UV light can therefore be employed without injurious affects.

Abstract: Among other things, a degree is determined to which values of a feature that characterizes cases correctly predict classes to which cases belong, the degree depending on a combination of at least two factors that include: (a) uncertainty about the values that the feature will have depending on knowledge about classes to which cases belong, and (b) comparison of one or more first values of the feature that are associated with cases that belong to a first class with one or more second values of the feature associated with cases belonging to a second class.

Abstract: A target digital image is received from an image sensor. The image is contaminated by noise of unknown magnitude that is represented by a reference digital image. A process is applied that uses statistical analysis of the target digital image and of the reference digital image to estimate a magnitude of the noise for at least some pixels of the target digital image.

Abstract: Among other things, on a two-dimensional electronic display, a representation is shown of a scanned image of a lesion on the skin of a real human. On the two-dimensional electronic display, a recommendation is indicated of a next diagnostic or treatment step to be taken, based on a computer-implemented analysis of the scanned image.

Abstract: Among other things, a portable memory card that conforms to a size, shape, and connection interface of an industry-standard memory card is smaller than and held by a support that conforms to a shape and size of an industry-standard credit card. The support is insertable into a receptacle with the connection interface of the memory card mated with a corresponding connection interface of the receptacle.

Abstract: Among other things, a movable medical device cart has a work surface on a pedestal and legs under the pedestal, an electronic device accessible at the work surface in connection with performing a medical procedure, and a computer mounted near a bottom of the pedestal to sink heat away from the computer.

Abstract: Among other things, a texture of an image is characterized by deriving lacunarity measures from the image based on a wavelet analysis.

A process is applied that uses statistical analysis of the target digital image and of the reference digital image to estimate a magnitude of the noise for at least some pixels of the target digital image.

Abstract: Skin characteristics are analyzed. A device acquires a digital image of an area of skin of a user. A processor quantitatively analyzes the digital image to determine a characteristic of all or part of the area of skin which is indicative of a skin condition of interest. Depending on the results of the quantitative analysis, the processor provides information to the user about the area of skin relative to the condition of interest. The information provided to the user is not necessarily sufficient for a definitive medical diagnosis and may include an indication to the user as to whether a knowledgeable person should evaluate the area of skin.
