  • Publication number: 20120053429
    Abstract: 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.

  • Publication number: 20050108049
    Abstract: A clinical practice guideline can be implemented using a guideline execution engine. The engine can interpret the clinical practice guideline, obtain medical data stored in a clinical information system (CIS), and implement an action in response to execution of the clinical practice guideline based on medical data for a patient obtained from the CIS. The use of the CIS medical data in guideline execution beneficially allows the guideline to be tightly integrated into the real-time workflow of a clinician in a clinical setting and to provide patient-specific guideline recommendations. A VMR/actions interface facilitates communications between a guideline execution system and a CIS by processing a request for medical data from the guideline execution engine and implementing actions on the CIS requested by the guideline execution engine.

  • Publication number: 20050007584
    Abstract: Hyperspectral imaging calibration devices and methods for their use are described that generate images of three dimensional samples. A calibration device may assume the shape of a desired imaging sample such as a body part and may be sterile prior to placement. The calibration device may include openings or may be modified to expose a region of the sample during use. Spectral images, typically obtained at multiple wavelengths, are made of the calibration device. Algorithms are provided that utilize the spectral images of the calibration device to determine the effects of lighting conditions and sample shape on the sample image to form a calibrated image. Calibrated images produced by these devices and methods can provide information, including clinical data that are less sensitive to lighting and sample shape compared to alternative technologies.

  • Publication number: 20020133080
    Abstract: The invention relates to fluorescence calibration devices and methods that can mimic skin and other tissues. A calibration device of the invention comprises at least one scattering layer, which is preferably non-fluorescent, and a second layer containing one or more fluorophore. Light passes through the scattering layer and excites the fluorophore. Light emitted from the fluorophore passes back though the scattering layer and into collecting optics, which can be measured and that measurement used to correct for instrument drift.

  • Publication number: 20010039483
    Abstract: This invention relates to the reduction of inter-subject variation via transfer standardization. According to the method, the effects of inter-subject variation on the analysis of spectra collected from the skin of two or more different subjects is reduced by correcting for the differences between spectra collected from said two or more subjects.
