Patent number: 8755579Abstract: Apparatus for and method of fully automatic rapid scanning and digitizing of an entire microscope sample, or a substantially large portion of a microscope sample, using a linear array detector synchronized with a positioning stage that is part of a computer controlled microscope slide scanner. The invention provides a method for composing the image strips obtained from successive scans of the sample into a single contiguous digital image. The invention also provides a method for statically displaying sub-regions of this large digital image at different magnifications, together with a reduced magnification macro-image of the entire sample. The invention further provides a method for dynamically displaying, with or without operator interaction, portions of the contiguous digital image. In one preferred embodiment of the invention, all elements of the scanner are part of a single-enclosure that has a primary connection to the Internet or to a local intranet.Type: GrantFiled: February 20, 2013Date of Patent: June 17, 2014Assignee: Leica Biosystems Imaging, Inc.Inventor: Dirk G.

Patent number: 8743195Abstract: A whole slide fluorescence digital pathology system is provided that uses a monochrome TDI line scan camera, which is particularly useful in fluorescence scanning where the signal is typically much weaker than in brightfield microscopy. The system uses oblique brightfield illumination for fast and accurate tissue finding and employs a unique double sweep focus scoring and objective lens height averaging technique to identify focus points and create a focus map that can be followed during subsequent scanning to provide autofocusing capability. The system also scans and analyzes image data to determine the optimal line rate for the TDI line scan camera to use during subsequent scanning of the digital slide image and it also creates a light profile to compensate for loss of illumination light due to roll off.Type: GrantFiled: October 23, 2009Date of Patent: June 3, 2014Assignee: Leica Biosystems Imaging, Inc.Inventors: Peyman Najmabadi, Gregory J. Crandall, Aaron Alan Stearrett, Dirk G. Soenksen, Christopher Adam Lee, Cynthia Perz

Patent number: 8737714Abstract: A portion of imagery data is obtained from a digital slide and a protocol of image analysis/diagnostic tasks is performed on the portion of imagery data by a pathologist or an image analysis module. The result of each task (e.g., success or no success) is recorded and a score is determined for the portion of the imagery data. Multiple portions of imagery data from the digital slide are analyzed and scored and the various scores from the multiple portions of imagery data are calculated to determine an overall score for the digital slide. Regions of the digital slide can be scored separately. Multiple rounds of scoring (by different pathologists and/or different image analysis algorithms) may be employed to increase the accuracy of the score for a digital slide or region thereof.Type: GrantFiled: September 20, 2011Date of Patent: May 27, 2014Assignee: Leica Biosystems Imaging, Inc.Inventor: Dirk G.

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. Crandall, Ole Eichhorn, Allen H. Olson, Dirk G. Soenksen

Patent number: 8705825Abstract: A digital slide analysis system comprises an algorithm server that maintains or has access to a plurality of image processing and analysis routines. The algorithm server additionally has access to a plurality of digital slide images. The algorithm server executes a selected routine on an identified digital slide and provides the resulting data. Prior to the application of selected routine, the system employs a digital pre-processing module to create a metadata mask that reduces undesirable image data such that the image data processed by the selected routine has an improved signal to noise ratio. The pre-processing module uses a classifier that may be implemented as a pattern recognition module, for example. Undesirable image data is therefore excluded from the image data that is processed by the digital pathology image processing and analysis routine, which significantly improves the digital pathology image analysis.Type: GrantFiled: February 9, 2012Date of Patent: April 22, 2014Assignee: Leica Biosystems Imaging, Inc.Inventors: Allen Olson, Ole Eichhorn

When a command is received from the leader client viewer, the command is sent to each of the non-leader client viewers to synchronize a view of the digital slide image at the non-leader client viewers with the view of the digital slide image at the leader client viewer.Type: ApplicationFiled: November 12, 2013Publication date: March 6, 2014Applicant: Leica Biosystems Imaging, Inc.Inventors: Ole Eichhorn, Anne Brumme

Publication number: 20140044346Abstract: Systems and methods for creating and viewing three dimensional digital slides are provided. One or more microscope slides are positioned in an image acquisition device that scans the specimens on the slides and makes two dimensional images at a medium or high resolution. These two dimensional digital slide images are provided to an image viewing workstation where they are viewed by an operator who pans and zooms the two dimensional image and selects an area of interest for scanning at multiple depth levels (Z-planes). The image acquisition device receives a set of parameters for the multiple depth level scan, including a location and a depth. The image acquisition device then scans the specimen at the location in a series of Z-plane images, where each Z-plane image corresponds to a depth level portion of the specimen within the depth parameter.Type: ApplicationFiled: October 22, 2013Publication date: February 13, 2014Applicant: Leica Biosystems Imaging, Inc.Inventors: Ole Eichhorn, Greg Crandall, Steven Hashagen, Dirk Soenksen, Mark Wrenn

Publication number: 20140046686Abstract: Systems and methods are provided to facilitate consultations between a referral source (e.g., labs, pathologists and patients) and a consultant (e.g., pathologist, radiologist, or other digital image analyst). Links between the various referral sources and consultants are established through a scanning center via a data communication network such as the Internet. The referral source sends a slide to the scanning center where the corresponding digital slide is posted for review and analysis by the consultant. Upon completion of the analysis and report, a digital slide conference is conducted through the scanning center that provides a venue for direct communication regarding the consultation. The scanning center may also facilitate payment from the referral source to the consultant.Type: ApplicationFiled: October 22, 2013Publication date: February 13, 2014Applicant: Leica Biosystems Imaging, Inc.Inventors: Dirk G.

Patent number: 8620047Abstract: Systems and methods for retrieving, manipulating, and viewing 3D image objects from 3D virtual microscope slide images (“3D digital slides”) are provided. An image library module provides access to the imagery data in a 3D digital slide and constructs 3D image objects that are coextensive with the 3D digital slide or a 3D sub-portion thereof. From within the 3D image object, cross layer planar views spanning various depths of the 3D digital slide are constructed as well as 3D prisms and other shaped image areas. The image library module allows a 3D image object to be sliced into horizontal and vertical views, skewed cross layer views and regular and irregular shaped 3D image areas for viewing by a user.Type: GrantFiled: May 29, 2012Date of Patent: December 31, 2013Assignee: Leica Biosystems Imaging, Inc.Inventor: Ole Eichhorn
