Software for image analysis includes a full suite of HALO® programs (Indica labs) plus Phenochart and phenoptr packages for viewing and analyzing spatial relationships in tissue sections. Color deconvolution (CD) algorithms are based on the Beer-Lambert law and require either a priori knowledge or estimation of color vectors of each specific stain, which are to un-mix the stain. A hyperspectral map of a fixed human cell was collected by a Raman micro spectrometer in a raster pattern on a 0.5um grid. Alternatively, a 5 ml volumetric pipette fitted with a pipette rubber squeeze-bulb also works well. Application of independent component analysis (ICA) as an unmixing and image clustering technique for high spatial resolution Raman maps is reported. A vertical 'line' of colored fluid is squirted into the apparatus by means of a hypodermic syringe fitted with a large needle and long stainless-steel extension tube. Shown here is a dual immunofluorescence (plus DAPI) stain imaged on the Vectra and ready for quantification of epithelial-mesenchymal transition in eosphageal epithelium. A few drops of food coloring mixed into about 10 ml of fluid works well. Vectra® microscopy systems (Akoya Biosciences) combine machine learning with multispectral color unmixing, providing the capability of analyzing multiple molecular targets in a single tissue sample. developed an unmixing algorithm 9 to unmix the RGB. This facility performs automated staining using Leica autostainers and a Leica Aperio AT2 for high throughput whole slide scanning. As the most widely used method in the digital pathology domain, Ruifrok et al. The RHTIC covers a comprehensive range of pathology services for animal and human tissue, from tissue processing and slide preparation to multiplex staining and advanced image analysis. Emphasizing close cooperation between slide preparation and digital imaging allows the facility to address a wide range of challenges involving single or multiplex stains. Inverting the Output Brightfield color imaging is a subtractive process where we start with white light and the dyes absorb various components of the white spectrum. The Department of Pathology and the UIC Research Resources Center jointly manage the RHTIC, a pair of core laboratories created in 2011 that provide histology and imaging services to investigators both within and beyond campus. Storing colour histological images digitally opens the possibility to process numerically colour distribution and intensity to extract quantitative data. Research Histology and Tissue Imaging Core Facility.In practice, however, they are influenced by many factors. Often it is assumed that these stain vectors are static. However, color deconvolution requires stain color vectors for accurate unmixing.

Continuous Professional Development/CME Color deconvolution (CD) is one of the most popular first steps in quantifying stain density in histopathological images.
