摘要： Methods, systems, and apparatuses for detecting and describing heterogeneity in a cell sample are disclosed herein. A plurality of fields of view (FOV) are generated for one or more areas of interest (AOI) within an image of the cell sample are generated. Hyperspectral or multispectral data from each FOV is organized into an image stack containing one or more z-layers, with each z-layer containing intensity data for a single marker at each pixel in the FOV. A cluster analysis is applied to the image stacks, wherein the clustering algorithm groups pixels having a similar ratio of detectable marker intensity across layers of the z-axis, thereby generating a plurality of clusters having similar expression patterns.

摘要： Immunohistochemistry (IHC) and in situ hybridization (ISH) have the aim of detecting, localizing and quantifying certain analytes for various diagnostic purposes. The quality of the stains which are analyzed may deviate for various reasons. Therefore, the present invention provides a method and system for assessing the stain quality and for establishing objective criteria for assessing the stain quality for application in the fields of in-situ hybridization and immunohistochemistry. In one possible embodiment, the invention comprises the steps of unmixing multi-spectral image data of a tissue specimen to obtain analyte intensity images, each analyte intensity image comprising signals from a single stain, computing metrics based on the analyte intensity images, wherein the metrics are uniformity, distribution and/or dispersion of pixel intensity values in the analyte intensity images and assessing a stain quality of a slide by comparing the computed metrics to pre-determined cutoff values regarding uniformity, distribution and/or dispersion of pixel intensity, wherein the stain quality of the slide is assessed as acceptable if the computed metrics meet or exceed the pre-determined cutoff values, and wherein the stain quality of the slide is assessed as unacceptable if the computed metrics do not meet the pre-determined cutoff values. In order to establish objective criteria for assessing stain quality, in one possible embodiment, the method and system includes the step of deriving cut-off values for uniformity, distribution and/or dispersion of pixel intensity by combining the computed metrics based on the analyte intensity images with pre-established data quantifying the stain quality.
