  • Patent number: 11422355
    Abstract: 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.

  • Patent number: 11237375
    Abstract: A system and a method for measuring the focus state of an optical instrument are described. The system and the method provide for forming an image of the exit pupil of the objective of the optical instrument. Where the image of the exit pupil is formed, one or more optical elements are placed, deviating at least part of the rays coming from the exit pupil, so that rays coming from different non-overlapping portions of the pupil follow separate optical paths. The rays coming from the two portions of the pupil are then focused, in order to obtain two bidimensional images. A computer determines the mutual distance between these two bidimensional images as a mutual rigid lateral displacement between the two and, based on this distance, determines the corresponding defocus of the optical instrument.

  • Patent number: 11231575
    Abstract: 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.

  • Patent number: 11169089
    Abstract: A measurement chip including a prism, a metal film, and a capturing body is prepared. In a state in which a specimen is present on the metal film, scattered light obtained when first light which passes through the metal film and the specimen is scattered in the specimen when the first light is applied to the metal film from a prism side at a first incident angle smaller than a critical angle is detected. In a state in which a substance to be measured is captured by the capturing body and the specimen is not present on the metal film, a signal indicating an amount of the substance to be measured generated in the measurement chip when second light is applied to the metal film at a second incident angle not smaller than the critical angle from the prism side is detected. On the basis of a hematocrit value of the specimen determined from a light amount of the scattered light, a measurement value indicating the amount of the substance to be measured determined from the signal is corrected.
