Patent number: 9841590Abstract: Systems and methods for capturing a digital image of a slide using an imaging line sensor and a focusing line sensor. In an embodiment, a beam-splitter is optically coupled to an objective lens and configured to receive one or more images of a portion of a sample through the objective lens. The beam-splitter simultaneously provides a first portion of the one or more images to the focusing sensor and a second portion of the one or more images to the imaging sensor. A processor controls the stage and/or objective lens such that each portion of the one or more images is received by the focusing sensor prior to it being received by the imaging sensor. In this manner, a focus of the objective lens can be controlled using data received from the focusing sensor prior to capturing an image of a portion of the sample using the imaging sensor.Type: GrantFiled: March 13, 2013Date of Patent: December 12, 2017Assignee: LEICA BIOSYSTEMS IMAGING, INC.Inventors: Yunlu Zou, Greg J. Crandall, Allen Olson

Patent number: 9729749Abstract: Systems and methods for capturing image data using a line scan camera. In an embodiment, a line scan camera captures image data of a sample as a plurality of image stripes. A processor may coarsely align two or more of the plurality of image stripes according to a synchronization process while the line scan camera is capturing at least one of the plurality of image stripes. Subsequently, the processor may also finely align the two or more image stripes using pattern matching.Type: GrantFiled: December 12, 2016Date of Patent: August 8, 2017Assignee: LEICA BIOSYSTEMS IMAGING, INC.Inventors: Greg J. Crandall, Ole Eichhorn, Allen H. Olson, Dirk G. Soenksen

Patent number: 8731260Abstract: Systems and methods for processing, storing, and viewing extremely large imagery data rapidly produced by a linear-array-based microscope slide scanner are provided. The system receives, processes, and stores imagery data produced by the linear scanner as a series of overlapping image stripes and combines the data into a seamless and contiguous baseline image. The baseline image is logically mapped into a plurality of regions that are individually addressed to facilitate viewing and manipulation of the baseline image. The system enables dynamic imagery data compression while scanning and capturing new image stripes that eliminates the overhead associated with storing uncompressed image stripes. The system also creates intermediate level images, thereby organizing the baseline image into a variable level pyramid structure referred to as a virtual slide.Type: GrantFiled: January 10, 2012Date of Patent: May 20, 2014Assignee: Leica Biosystems Imaging, Inc.Inventors: Greg J.

Patent number: 7428324Abstract: A data management system and method for processing, storing, and viewing the extremely large imagery data that is rapidly produced by a linear-array-based microscope slide scanner is provided. The system receives, processes, and stores imagery data produced by the linear-array-based microscope slide scanner at approximately 3 GB per minute. The data are received as a series of overlapping image stripes and combined into a seamless and contiguous baseline image. The baseline image is logically mapped into a plurality of regions that are individually addressed to facilitate viewing and manipulation of the baseline image. The data management system enables imagery data compression while scanning and capturing new image stripes. This advantageously eliminates the overhead associated with storing uncompressed image stripes.
