Apparatuses, Methods and Computer Programs for Controlling a Microscope System
Examples relate to apparatuses, methods and computer programs for controlling a microscope system, and to a corresponding microscope system. An apparatus for controlling a microscope system comprises an interface for communicating with a camera module. The camera module is suitable for providing camera image data of a head of a user of the microscope system. The apparatus comprises a processing module configured to obtain the camera image data from the camera module via the interface. The processing module is configured to process the camera image data to determine information on an angular orientation of the head of the user relative to a display of the microscope system. The processing module is configured to provide a control signal for a robotic adjustment system of the microscope system based on the information on the angular orientation of the head of the user.
QUANTITATIVE AND AUTOMATED PERMEABILIZATION PERFORMANCE EVALUATION FOR SPATIAL TRANSCRIPTOMICS
Quantitative methods for optimizing the permeabilization of cellular tissues for spatial transcriptomics are provided. Also provided is an instrument for quantitatively optimizing the permeabilization of cellular tissues used for spatial transcriptomics.
In-Vitro Contractile Force Indicator
Devices and methods to measure cells and/or tissue's contractile force are disclosed. Included is a mount with rigid, and non-rigid posts sized to flex. Determined is force exerted by contractile cells and tissues in a multiwell plate. The device is designed to fit inside individual wells with posts directed downwards. Posts are attached to a 3D printed circular mount with tabs for depth within the well. The mount has a window for medium changes while the device is positioned inside the well. The cells are seeded within a hydrogel. As the hydrogel condenses, cells/tissue wrap around the post's outside pulling non-rigid post toward rigid post. Inverted light microscope is used to determine deflection of non-rigid post inside the multiwell plate. Movement of the non-rigid post is measured using an acrylic ruler on an underside of the multiwell plate. Contractile forces of cells/tissue are determined using cantilever mechanics.
Method, computer program and microscope system for processing microscope images
In a method for processing microscope images, at least one microscope image is provided as input image for an image processing algorithm. An output image is created from the input image by means of the image processing algorithm. The creation of the output image comprises adding low-frequency components for representing solidity of image structures of the input image to the input image, wherein the low-frequency components at least depend on high-frequency components of these image structures and wherein high-frequency components are defined by a higher spatial frequency than low-frequency components. A corresponding computer program and microscope system are likewise described.
Identifying the quality of the cell images acquired with digital holographic microscopy using convolutional neural networks
A system for performing adaptive focusing of a microscopy device comprises a microscopy device configured to acquire microscopy images depicting cells and one or more processors executing instructions for performing a method that includes extracting pixels from the microscopy images. Each set of pixels corresponds to an independent cell. The method further includes using a trained classifier to assign one of a plurality of image quality labels to each set of pixels indicating the degree to which the independent cell is in focus. If the image quality labels corresponding to the sets of pixels indicate that the cells are out of focus, a focal length adjustment for adjusting focus of the microscopy device is determined using a trained machine learning model. Then, executable instructions are sent to the microscopy device to perform the focal length adjustment.
