Abstract: Detecting cells depicted in an image using RNA segmentation can include obtaining a FISH image of a tissue that depicts multiple cells, obtaining a nuclear stained image of the tissue, and generating a mask that includes multiple areas that each have a position with respect to the tissue by enhancing structures depicted in the FISH image. Edges depicted in the enhanced FISH image are detected to use for the mask, and positions are determined for a first plurality of regions that fit potential nuclei depicted in the nuclear stained image. A second plurality of regions are selected from the first plurality by determining, using the mask, which regions from the first plurality overlap with the position of an area from multiple areas in the mask. Unique nuclei in the tissue are labelled using the second plurality of regions that each indicate a potential nuclei in the tissue.

Abstract: A Multi-Z confocal microscopy system can simultaneously record from multiple Z-sections, and thus performs high speed volumetric imaging. An illumination line can be formed by under-filling the illumination beam in the aperture of the microscope objective. The illumination line extends in the Z dimension into the target sample to be imaged and an X-Y scanning mechanism can be used to scan the illumination line over the sample. The detection signal emanating from the scanned sample can be collected through the full numerical aperture of the microscope objective and directed to a detector subsystem. The detector subsystem includes an array of reflecting pinhole detectors and each reflecting pinhole detector is configured to image a volume at a different depth in the sample. This configuration enables reflecting pinhole detector array to image more than one depth volume at the same time.
