The present techniques include methods and systems for finding correspondences between tissue spots in tissue microarray serial sections belonging to the same recipient block. The present techniques may also be used to relate individual tissue cores to clinical information. Using either a whole slide image or the relative x-y coordinates of the tissue spots on the slide, individual tissue spots in different tissue microarrays may be linked to one another and their clinical information.

Cancer can be an aggressive disease. It is critical to determine the most effective patient-specific treatment quickly. Exemplary embodiments use a data-driven approach to extracting tumor information from data obtain from Whole Slide Image that is uploaded through an interface. Exemplary embodiments generate the following information about a tumor from a biopsy slide using neural networks: annotated areas of relevant tissues, molecular subtype, and expression status of an important gene and include three steps: the segmentation of tumor features; prediction of molecular subtype; and prediction of gene methylation status from a WSI.

Advantageous instruments, assemblies and methods are provided for undertaking imaging techniques (e.g., microscopic imaging techniques). The present disclosure provides improved imaging techniques, equipment and systems. More particularly, the present disclosure provides advantageous microscopy / imaging assemblies with rapid sample auto-focusing (e.g., microscopy / imaging assemblies having instant focusing for rapid sample imaging with auto-focusing). The present disclosure provides for high-throughput whole slide imaging with instant focal plane detection. A whole slide imaging platform / assembly that uses instant focusing systems / methods for high-speed sample autofocusing is provided. Such exemplary platforms / assemblies can be used for digital pathology or the like, and can provide improved, faster and cheaper diagnosis / prognosis of ailments / diseases. At least two exemplary rapid-focus systems for whole slide imaging are provided, a first system including two pinhole-modulated cameras mounted on the eyepiece ports of a microscope platform / assembly, and a second system including one pinhole-modulated camera mounted on the epi-illumination arm for auto-focusing.

Glioblastoma multiforme (GBM) is the most aggressive type of brain cancer. It is critical to determine the most effective patient-specific treatment quickly. Exemplary embodiments use a data-driven approach to extracting brain tumor information from data obtain from Whole Slide Image that is uploaded through an interface. Exemplary embodiments generate the following information about a glioblastoma tumor from a brain biopsy slide using neural networks: annotated areas of relevant tissues, molecular subtype, and expression status of an important gene and include three steps: the segmentation of tumor features; prediction of molecular subtype; and prediction of gene methylation status from a WSI.

Methods, systems, and apparatuses for automatically identifying glandular regions and tubule regions in a breast tissue sample are provided. An image of breast tissue is analyzed to detect nuclei and lumen candidates, identify tumor nuclei and true lumen from the candidates, and group tumor nuclei with neighboring tumor nuclei and lumina to define tubule glandular regions and non-tubule glandular regions of the image. Learnt supervised classifiers, such as random forest classifiers, can be applied to identify and classify the tumor nuclei and true lumina. Graph-cut methods can be applied to group the tumor nuclei and lumina and to define the tubule glandular regions and non-tubule glandular regions. The analysis can be applied to whole slide images and can resolve tubule areas with multiple layers of nuclei.

The present disclosure includes systems and methods for capture a whole slide image of a sample. In exemplary embodiments, a camera is configured to capture a digital image of a sample. The system captures a bright field image of the sample, and captures a digital image of the sample illuminated from a first incident angle at a first wavelength and a second incident angle at a second wavelength. The system can determine whether the sample is defocused based on the transitional shift between a first wavelength channel and a second wavelength channel of the captured digital image. The system can determine the defocus distance based on the transitional shift and autofocus using the defocus distance such the bright field image is in focus.
