Method of preparing a stage for use in a slide imaging apparatus
A method of preparing a stage for use in a slide imaging apparatus including positioning a stage in relation to a flat surface so that the flat surface is positioned in front of the top surfaces of slide support pin bases on the top surface of the stage. The method also includes injecting a fluid pin surfacing material configured to solidify into the hole of each slide support pin base so that at least some of the fluid pin surfacing material exits the hole at the top surface of the slide support pin bases and pushes up against the flat surface. The method also includes removing the flat surface so that a tip of solid pin surfacing material is formed on the top surface of each slide support pin base, thereby providing the stage with a plurality of slide support pins.

Method and System for Acquisition of Fluorescence Images of Live-cell Biological Samples
A method is disclosed for acquiring a single, in-focus two-dimensional projection image of a live, three-dimensional cell culture sample, with a fluorescence microscope. One or more long-exposure “Z-sweep” images are obtained, i.e. via a single or series of continuous acquisitions, while moving the Z-focal plane of a camera through the sample, to produce one or more two-dimensional images of fluorescence intensity integrated over the Z-dimension. The acquisition method is much faster than a Z-stack method, which enables higher throughput and reduces the risk of exposing the sample to too much fluorescent light. The long-exposure Z-sweep image(s) is then input into a neural network which has been trained to produce a high-quality (in-focus) two-dimensional projection image of the sample. With these high-quality projection images, biologically relevant analysis metrics can be obtained to describe the fluorescence signal using standard image analysis techniques, such as fluorescence object count and other fluorescence intensity metrics (e.g., mean intensity, texture, etc.).

Systems for fluorescence light sheet microscopy of large samples in high refractive index solutions
Systems for allowing adjustable imaging of specimens of various sizes in solutions of various refractive indices, such as those with a refractive index of at least 1.45, for use in microscopes such as fluorescent light sheet microscopes. The systems allow for imaging large specimens in various refractive indices while maintaining the highest optical sectioning provided by the objectives used across the full range of microscope stage travel. The systems also allow the use of a wider range of optics, such as low magnification 2.5× detection objectives, allowing for increased imaging speed and field of view.
Virtual slide stage (VSS) method for viewing whole slide images
Embodiments provide slide navigation technology that addresses challenges in digital pathology of navigating and viewing high resolution slide images. Example systems comprise a virtual slide stage (VSS) having at least one sensor that detects user movement of a target placed on the VSS, and an input component, coupled to the VSS, which provides quick function movement control of the target via quick functions. The systems also comprise a connector component that connects the VSS to a user device and transmits output from the at least one sensor and input component to the user device. The systems further comprise a computer processor, in communication with the VSS, which processes the output using a computational model to generate data representing movement profiles of the target. The computer processor executes a software component, causing the output, translated based on the movement profiles, to be relayed via a viewing application on the user device.
