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.
SAMPLE TRANSFER DEVICE
A sample transfer device (100) for receiving a sample inside the sample transfer device (100) and for transferring the sample to a processing or analysing unit includes a connection opening (110) defining a transfer path (114) along which the sample is to be transferred from a loading position (120) of the sample inside the sample transfer device (100) through the connection opening (110), a shutter (130) configured to block the connection opening (110) or to unblock the connection opening (110), and a shielding member (140) configured to be arranged between the connection opening (110) and the loading position (120) to protect the sample from an incoming gas stream when the shutter (130) unblocks the connection opening (110).
SYSTEM FOR LOADING AND/OR MANIPULATING A SAMPLE IN A SAMPLE TRANSFER DEVICE
A system (100) for loading a sample into and/or manipulating a sample in a sample transfer device (180) at cryogenic temperatures, comprising the sample transfer device (180) being configured to receive a sample through a receiving opening (182) of the sample transfer device (180) and configured to transfer the sample to a processing or analysing unit, and a dry box (110) having an interface opening (112) and being configured to be coupled to the sample transfer device (180) such that the interface opening (112) of the dry box (110) is located opposite the receiving opening (182) of the sample transfer device (180).
HIGH CONTENT IMAGING SYSTEM AND A METHOD OF OPERATING THE HIGH CONTENT IMAGING SYSTEM
A high content imaging system and a method of operating the high content imaging system are disclosed. A microscope has a first objective lens and a second objective lens, and an objective lens database has first and second transformation values associated with the first and the second objective lenses, respectively. A microscope controller operates the microscope with the first objective lens to develop first values of acquisition parameters. A configuration module automatically determines second values of the acquisition parameters using the first values of the acquisition parameters, first transformation values associated with the first objective lens, and second transformation values associated with the second objective lens. The microscope controller operates the microscope using the second objective lens and the second values of the acquisition parameters.

METHOD FOR CONFIGURING AN AUTOMATED MICROSCOPE, MEANS FOR IMPLEMENTING THE METHOD, AND MICROSCOPE SYSTEM
A method for configuring a sequence controller of an automated microscope includes, in a learning operating mode, performing training settings in succession. Each training setting corresponds to a respective setting data set of microscope components. A user brings at least a part of the microscope components into positions, and assigns each respective position to one or more examination steps to be performed by the microscope components. The method further includes assessing the training settings after the training settings are performed, and based on the assessment, storing the setting data sets associated with the training settings for subsequent use in the sequence controller, and/or discarding the setting data sets, and/or modifying the setting data sets. The sequence controller specifies a use of the stored setting data sets in the form of a setting of the microscope components in an examination operating mode following the learning operating mode.
Systems and methods for serial staining and imaging
The present invention relates to systems and methods for sequential operation of staining, imaging and sectioning of tissue samples by a processing system. After each layer of the sample is removed by the sectioning system, the system automatically stains the exposed surface of a sample to a depth to enable imaging of the remaining tissue. The system then repeats the sectioning, staining and imaging steps in sequence to image the sample.

Autofocus device, and optical apparatus and microscope including the same
An autofocus device includes a stage, a magnifying optical system, a light source device, an iris which is arranged at a position opposite to a sample of the magnifying optical system and configured to limit a light beam emitted from the light source device, and an AF camera which receives, via the magnifying optical system, a reflected light beam which is reflected from a reflection surface after the light beam reaches a glass member via the iris and the magnifying optical system. The light source device emits the light beam at a non-zero angle relative to the axis of the magnifying optical system. The control unit adjusts the position of the stage so as to match the position of a captured image of a shield with a target position. With such a configuration, it is possible to achieve the autofocus at high speed.
