  • Publication number: 20230071078
    Abstract: There is proposed a method for detecting a presence of a fluorescence pattern type on an organ segment via immunofluorescence microscopy and digital image processing. The steps comprise: provision of the organ segment, incubation of the organ segment with a liquid patient sample, incubation of the organ segment with secondary antibodies which have been labelled with a fluorescent dye, acquisition of a fluorescence image of the organ segment in a colour channel corresponding to the fluorescent dye, and provision of the fluorescence image to a neural network. What takes place by means of the neural network is simultaneous determination of segmentation information through segmentation of the fluorescence image and, furthermore, of a measure of confidence indicating an actual presence of the fluorescence pattern type.

  • Publication number: 20220404283
    Abstract: A method for detecting at least one potential presence of at least one fluorescence pattern type on an organ section by means of immunofluorescence microscopy and by means of digital image processing is disclosed. An organ section is provided on a slide and the section is incubated with a liquid patient sample which potentially includes primary antibodies and with secondary antibodies which have been labelled with a fluorescent dye. A fluorescence image of the organ section is acquired. A determination is made, by segmentation of the fluorescence image by means of a first neural network, of a sub-area of the fluorescence image that is relevant to formation of the fluorescence pattern type. A determination is made, on the basis of the fluorescence image by means of a second neural network, of the measure of confidence that indicates an actual presence of the fluorescence pattern type.

  • Patent number: 11367187
    Abstract: A method is for detecting respective potential presence of respective different antinuclear antibody fluorescence pattern types on a biological cell substrate including human epithelioma cells, including: acquiring a first image which represents staining of the cell substrate by a first fluorescent dye, and acquiring a second image which represents staining of the cell substrate by a second fluorescent dye, detecting, on the basis of the first image, respective image segments which in each case represent at least one mitotic cell, selecting, on the basis of the detected image segments, subimages of the first image and subimages corresponding thereto of the second image and detecting, on the basis of the selected subimages of the first image and of the selected subimages of the second image, respective actual presence of respective cellular fluorescence pattern types by means of a convolutional neural network.

  • Patent number: 11305289
    Abstract: A method is useful for automated detection of antibodies in a liquid biological sample with an antigen chip having antigen spots which are applied thereon and which have an identical, common dye. The antigen spots form respective antigen spot sets which form corresponding respective, regular antigen spot patterns. Furthermore, reference spots comprising the identical dye are applied, and form a reference spot set which forms a regular reference pattern. The reference pattern differs with respect to its regularity from the antigen spot patterns. Through a first image information item which represents a color of the reference spots and of the antigen spots due to the identical, first dye and through a second image information item which represents a potential color of the antigen spots due to a second dye after an incubation, binding of antibodies of the biological sample to respective antigen types is then determined by image processing.
