    Abstract: For acquisition of spatial transcriptomic information, one or more filters are applied to deconvolution is performed on each image of a plurality of images to generate a plurality of filtered images, and registration of the plurality of filtered images is performed to generate a plurality of registered and filtered images. For each pixel of at least two pixels of the plurality of registered and filtered images, the pixel is decoded by identifying a code word from a plurality of code words in a code book that provides a best match to data values in the plurality of registered and filtered images for the pixel. For each pixel of at least two pixels, a gene is associated with the code word is determined and an indication that the gene is expressed at the pixel is stored.

    Abstract: A fluorescent in-situ hybridization imaging and analysis system includes a flow cell to contain a sample to be exposed to fluorescent probes in a reagent, a fluorescence microscope to obtain sequentially collect a plurality of images of the sample at a plurality of different combinations of imaging parameters, and a data processing system. The data processing system includes an online pre-processing system configured to sequentially receive the images from the fluorescence microscope as the images are collected and perform on-the-fly image pre-processing to remove experimental artifacts of the image and to provide RNA image spot sharpening, and an offline processing system configured to, after the plurality of images are collected, perform registration of images having a same field of view and to decode intensity values in the plurality of images to identify expressed genes.

    Abstract: In acquisition of spatial transcriptomic information, a plurality of images representing a common field of view of a sample are obtained and registered. Each pixel of the registered images is decoded by identifying a code word from a plurality of code words in a code book that provides a best match to data values in the plurality of registered images for the pixel. For each code word identified as a best match and each pixel, whether a bit ratio for an image word for the pixel meets a threshold for the code word is determined. The image word is formed from the data values in the plurality of registered images for the pixel. For at least one pixel that is determined to meet the threshold, a gene associated with the code word is determined. Pixels for which the bit ratio does not meet the threshold are screened.
