    摘要: A method for the selective determination of the scattering index μs of a scattering biological matrix, in particular for the purpose of non-invasive determination of the concentration of glucose in the skin, by means of detection measurements, in each of which light in the form of primary light (9) is irradiated into the biological matrix (5) and an intensity measurement value of secondary light (12) exiting at a detection site (33-40) that is located at different measuring distances (ρ) from the respective light irradiation site (10) during the detection measurements is measured. In order to improve the quality and selectivity of the determination of μs, the primary light is irradiated obliquely at an angle between 5° and 85° using a contacting light-guiding element. In at least two detection measurements, the measuring distance (ρ) between the respective light irradiation site (10) and the respective detection site (33-40) corresponds to no more than five times the mean free path length of the light propagating in the biological matrix.

    摘要: A method is proposed for the selective determination of a light transport parameter which is characteristic for the light scattering in a biological matrix (5), in particular for the purpose of the non-invasive determination of the glucose concentration in the biological matrix. The method comprises providing a plurality of detection measurements, in which light is irradiated as primary light into the biological matrix and measuring an intensity value of secondary light emerging at a plurality detection sites, located in different measuring distances from the irradiation site. In an evaluation step, the light transport parameter is derived, by means of an evaluation algorithm, from the measured intensity values. For the selective determination of the scattering coefficient, the evaluation algorithm includes a step in which a time derivative value ΔtI(r) describing the change of the measurement intensity value versus time is calculated from intensity measurement values obtained at a minimum of two different points of time.

    摘要: The invention relates to analysis methods for diagnosing diseases on human and animal samples. Said invention also relates to an evaluation method for diagnosing the individual stages of a disease in such a way that it is possible to display the progression thereof. Said invention also makes it possible to identify diseases in an early manner and to carry out therapeutic controls. The inventive method consists in carrying out actually known multivariable evaluation methods for classifying samples. Nevertheless, the invention is characterised in that no sample is allocated to a certain class, but it is classified in a data record based on the interpolation between different classes.
