Patent number: 10769782Abstract: Exemplary method, computer-accessible medium and system can be provided for determining the presence or absence of a local and/or global property of a biological tissue sample. Thus, it is possible to obtain at least one image of the sample, search the image(s) for a presence of at least one particular feature that is contained in a pre-defined set of features, and assign, to the particular feature(s). It is possible to compute, with a computer processor, at least one discriminant value that is a function of the pronunciation index that is weighted with a particular weight. The weight of each pronunciation index is a measure for a relevance of the corresponding feature with respect to the property. It is possible to determine whether the property is present in at least one part of the biological tissue sample depending on whether the discriminant value exceeds a pre-defined threshold and/or and optimized threshold.Type: GrantFiled: December 13, 2016Date of Patent: September 8, 2020Assignees: Leibniz-Institut für Photonische Technologien e.V., Friedrich-Schiller-Universität JenaInventors: Jürgen Popp, Thomas Bocklitz, Olga Chernavskaia, Tobias Meyer

Publication number: 20110165558Abstract: Individual viruses in any type of sample are identified quickly, unambiguously and reliably, and with the least possible preparation-related and technology-related expenditure, without necessitating immobilization using antibodies and without requiring an indication or at least a suspicion of potentially present viruses. This is accomplished by scanning the height profile of the sample, from which scanning sites suspected of containing viruses are selected, exposing those cites to monochromatic excitation light and spectroscopically analyzing the resulting Raman scattered light.Type: ApplicationFiled: July 21, 2009Publication date: July 7, 2011Inventors: Jürgen Popp, Volker Deckert, Dieter Naumann, Robert Möller, Dana Cialla
