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： A preview station for previewing microscope slides where each slide has one or more specimens thereon, the preview station having a tray holder supporting a slide tray with a plurality of slides thereon. A digital camera and lens is located on an optical axis relative to the slide tray and a light source illuminates the slide tray. The camera is activated to image each slide in the slide tray and has a memory to store and transmit data from each slide. The preview station can be used in combination with a scanning system and can be made part of a scanning system.

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： Computer-implemented methods and systems are provided for curating medical images for a medical image database. An example method for curating involves operating a processor to obtain a query medical image, assign the query medical image to an initial set of related images, and generate a similarity indicator for each image of the initial set. The similarity indicator is representative of a measure of similarity between image data of that image and the initial set. The processor is operable to define an intermediate set from the initial set based on the similarity indicators; and generate a relevancy indicator for each image of the intermediate set. The relevancy indicator is representative of a measure of the relevancy between relevance of the image and the intermediate set. The processor is operable to define a curated set of images from the intermediate set based on the relevancy indicators.

摘要： A content-based image retrieval (CBIR) system and method is presented herein. The CBIR system generates a relatively short vector or array of data, referred to as a barcode, from an input image. The short vector or array data can be used to represent the content of the image for image retrieval purposes. The system obtains the image and applies a transform to the image to generate a plurality of image transform values. The system thresholds the plurality of image transform values to obtain compact image transform values. The system generates a barcode in accordance with the compact image transform values and representative of the image. The system may then transmit the barcode to a database for storage or draw the barcode on a display. The system may also compare barcodes to find and retrieve similar images associated with similar barcodes.
