Systems and methods of utilizing communications networks and multivariate analysis to predict or recommend optimal products from a predefined population of commercially available products are disclosed. The recommendations are based on intelligence contained in processing elements and subjective and/or objective product information received from consumers or input to the systems as part of their initial setup. The output of the systems comprise sets of products that they predict the consumer will prefer and/or perform well for the problem or concern identified by the consumer. The performance and preference predictions are a function of consumer problems and product responsiveness patterns. Objective product information is generally obtained with diagnostic instruments. Data measured with the diagnostic instruments may be communicated to the data processing portions of the invention via the Internet. The outputs of the data processing portion of the system may be presented to consumers via the Internet as well.
摘要:
An imaging station for taking a plurality of digital images of a subject under a plurality of illuminating conditions and storing and analyzing the digital images, includes a housing, containing the digital image capturing apparatus, like a camera or video recorder, a computer for processing the image data and one or more displays for displaying images of the person. The imaging station aids in controlling lighting during image capture and may be used to optimally position the subject for imaging. The computer may be programmed to conduct various image processing functions and may be networked to allow image sharing. A display which may be provided on the exterior of the housing allows an operator to visualize the subject and to control the imaging process. The imaging station may be used for teaching purposes.
摘要:
An apparatus and method for assessing photodamage has a digital imaging system for recording blue light imagining and in particular the green signal response intensity of the skin of a person, which is indicative of elastotic material and photodamage. Because the image data has a numerical intensity value, which may be expressed in RGB or L*a*b* colorspace, the image data taken from one image can be numerically compared to that of one or more other images and the image data is amenable to numerical and statistical analysis. Comparison to population profiles/image data permits an individual's image data to be characterized numerically, such as by a relative score or percentile rating. The image data can also be used to ascertain the degree of variation over a surface such as the face, with wider variation being indicative of greater photodamage.

摘要:
A system for conducting large scale clinical trials has a plurality of data collection nodes for collecting data from subjects participating in the clinical trial. A data analysis facility is located remotely from the data collection nodes and the data is communicated from the data collection nodes to the data analysis facility, where it is stored and analyzed. Each data collection node may include testing and data entry facilities, e.g., in the form of photographic equipment or various diagnostic and measuring probes, such as those used to measure skin color, elasticity and moisture content. The data nodes may be operated by the participant.
摘要:
The present invention relates to a method of photographing the skin of a person comprising: (i) illuminating the skin with at least one light source, wherein the light source emits substantially only light having a wavelength from about 380 to about 430 nm or emits light through a filter that emits substantially only light having a wavelength from about 380 to about 430 nm; and (ii) capturing the image of the illuminated skin with a camera; wherein the light entering the camera is also filtered with a long pass filter, wherein the long pass filter substantially eliminates light having a wavelength below about 400 nm.
摘要:
The method of the present invention is directed at detecting non-invasively and in vivo the rate of proliferation of epithelial cells in a human patient. The method is based on determining the optical spectra, preferably the fluorescence excitation spectra, from affected and non-affected areas of epithelial cells, and then comparing the two spectra from these regions. In particular, applicants have discovered that when human or animal skin is irradiated with light centered near 295 nm, fluorescence having a distinct maximum near 360 nm is induced.
摘要:
A non-invasive analyte monitoring instrument has a radiation source for directing excitation radiation to a portion of a surface of a tissue wherein said source emits radiation at a plurality of different wavelengths that excites a target in said tissue causing said target to emit radiation such that the radiation received at the surface provides an analyte level indication of the patient. A radiation detector positioned to receive radiation emitted from the surface wherein said radiation detector is configured to synchronously scan radiation emitted by the target with the excitation radiation. A processing circuit operatively connected to the radiation detector that translates radiation received at the surface to a measurable signal to obtain said analyte level indication, wherein said radiation source comprises a visible light source or an ultraviolet light source and wherein the target is selected from the group consisting of a structural matrix tissue component, a cellular tissue component, a mitochondrial tissue component, a collagen cross link, a pepsin-digestible collagen cross link, a collagenase-digestible collagen cross link, a non-pepsin digestible collagen cross link, an elastin cross link, a tryptophan-containing protein, NADH, FAD, a flavoprotein, and any combination thereof.
