    摘要: A Raman spectrum is measured inside animal tissue, such us human skin tissue, at a selected depth from a surface the tissue. A pH value is computed using a function that assigns a pH value as a function of the measured Raman spectrum. The computation may involve computing a number representing a ratio of concentrations of a protonated and a deprotonated version of a chemical substance from the Raman spectrum and generating pH information on the basis of said number. The chemical substance is for example a form of Urocanic acid (UCA). UV exposure is measured from the weight of the spectrum of cis-UCA.

    摘要: The present invention relates to a spectroscopic apparatus for non-invasive in vivo analysis of blood and to a corresponding analysis method, in particular for direct determination of the pH value of the blood. From a Raman signal detected from an excited target region containing blood at least one predetermined pH sensitive signal portion is determined, from which the pH value of the blood in the target region by use of a relationship between pH value and one or more band parameters of pH sensitive vibrations of at least one molecule or part of a molecule present in blood, in particular heme vibrations of hemoglobin, is determined.

    摘要: The present invention relates to an apparatus, a method and a computer program for determining a lipid-water ratio and a scattering parameter of a sample. In particular, the invention relates to an apparatus comprising a light source and a detector arranged to measure an optical parameter at various wavelengths, where the wavelengths are selected so that at two of the wavelengths the absorption coefficients for both water and lipids are substantially identical. This enables determination of a scattering parameter. A further measurement at a third wavelength enables determination of a water-lipid ratio. According to a specific embodiment, the light source and the detector are arranged in relation to an interventional device, so as to be able to examine a tissue in terms of lipid-water ratio and scattering during an intervention.

    摘要: A spectroscopic apparatus for determining a concentration and/or spatial gradient of an analyte of a bodily fluid that provides determination of a position of a capillary vessel within a biological sample in order to focus spectroscopic excitation radiation to a volume that is in close proximity to the capillary vessel but does not overlap with the capillary vessel. The provided apparatus exploits the permeability of the vessel wall with respect to an analyte that is subject to analyte concentration determination. By means of biological transport processes, the concentration of an analyte of a bodily fluid located in the capillary vessel influences the concentration in the surrounding of the capillary vessel. Spectroscopic analysis of a volume outside the capillary vessel can therefore serve for a precise and reliable analyte concentration determination inside the capillary vessel.
