摘要： An instrument and method for scanning a large microscope specimen uses a light source and at least one lens to focus light from the specimen onto a detector array. The specimen holder is located on a scanning stage and the detector array is dynamically tilted about a scan direction during the scan to maintain focus across the width of the scan strip as the scan proceeds. A degree of tilt varies during the scan as is required to maintain lateral focus relative to the detector array.

摘要： Computer-implemented methods and systems are provided for generating encoded representations for multiple magnifications of one or more query images. An example method for involves operating a processor to obtain a query image and identify a set of anchor points within the query image. The processor is operable to generate a plurality of sub-images for a plurality of magnification levels for each anchor point. Each sub-image includes the anchor point and corresponds to a magnification level of the plurality of magnification levels. The processor is operable to, for each magnification level, apply an artificial neural network model to a group of sub-images having that magnification level to extract a feature vector representative of image characteristics of the query image at that magnification level; and to generate an encoded representation for multiple magnifications of the query image based on the feature vectors extracted for the plurality of magnification levels.

摘要： An instrument and a method of scanning a large microscope specimen moves the specimen relative to a detector array during scanning by a scanner. Magnification of the instrument is adjustable using a zoom tube lens over a continuous range of magnification to enable scans of the specimen to be taken over a range of resolutions without varying the infinity corrective objective. Scans of the specimen can be taken over a range of resolutions with the same infinity connected objective.

摘要： An instrument and method for scanning a large specimen comprises a specimen holder to support the specimen, an optical system to focus an image of a series of parallel object planes onto one of a two dimensional detector array, multiple linear arrays, multiple TDI arrays and multiple two-dimensional arrays. The detector array has a detector image plane that is tilted relative to the series of object planes in a scanned direction to enable a series of image frames of the specimen to be obtained in order to produce a three-dimensional image of at least part of the specimen with data from each row of the image frame representing a different plane in the three-dimensional image.
