Patent number: 12014830Abstract: This invention provides a system for automation of a pathology process, which includes a processor having trained artificial intelligence (AI) modules operating in association therewith, adapted to receive image data from camera images of whole tissue acquired by a camera assembly and whole slide images (WSIs) of inked and segmented tissue samples. A mask produces image results for tissue with holes and free of holes, and a filter provides filtered image results to the AI modules, detecting tumors and macroarchitecture features. A quality assessment process produces quality score outputs for tumors and macroarchitecture features. A report generator provides reports with one or more parameters to a user via an interface. More particularly, the report generator automatically creates a pathology report, having a written description and pictorial diagram relative to the gross images of the tissue integrating the outputs of the AI modules used to analyze the whole slide digital images.Type: GrantFiled: April 18, 2022Date of Patent: June 18, 2024Assignee: Mary Hitchcock Memorial Hospital, for itself and on behalf of Dartmouth-Hitchcock ClinicInventors: Matthew LeBoeuf, Joshua J.

Patent number: 10013760Abstract: The present disclosure provides methods, systems, and computer-readable storage media that can be used to image an unstained sample. Traditionally histopathology and immunohistochemistry methods use stains or dyes in combination with microscopy (or other detection methods) to detect cells and cellular structures, such as proteins. However, the disclosed methods do not require the use of such stains and dyes. The disclosed methods can include obtaining a spectroscopic image (e.g., infrared (IR) imaging data) of the sample, analyzing the resulting spectroscopic image to reduce the dimensionality of the spectroscopic image, comparing the reduced spectroscopic image compared to a control (e.g., by using an appropriately trained algorithm) and generating an output computed stain image from the reduced IR spectra, thereby imaging the sample without the use of stains or dyes.Type: GrantFiled: August 2, 2017Date of Patent: July 3, 2018Assignee: BOARD OF TRUSTEES OF THE UNIVERSITY OF ILLINOISInventor: Rohit Bhargava

Patent number: 9955127Abstract: Full-color images of low-light scenes are generated by the systems and methods described herein using only two light channels. An array of photosensitive pixels includes two sets of pixels, the first sensitive only to light associated with a first light channel, the second only to light associated with a second light channel. Thus the first set of pixels generate a first set of electrical signals in response to incident light within the first light channel, and the second set of pixels generate a second set of electrical signals in response to incident light within the second light channel. An image processor receives the first and second sets of electrical signals and generates a full-color image of the scene by processing only signals generated by the first and second sets of pixels.Type: GrantFiled: October 30, 2015Date of Patent: April 24, 2018Assignee: CHROMATRA, LLC.Inventors: Peter W.

Publication number: 20130222531Abstract: A low-resolution image having a low resolution and low frequency band is generated from an image sensed by using a single board color image sensor, and pseudo color suppression and color noise suppression are performed on each of the image and low-resolution image. The resolution of the low-resolution image is then restored, and weighted combination is performed on this image and the former image. If it is determined that a pixel of interest belongs to a region where a pseudo color is generated, a MIX ratio calculator (205, 225) for calculating a ratio coefficient for combination calculates a ratio coefficient by which a color signal of a pixel of the low-resolution image having the restored resolution is the result of the weighted combination. This makes it possible to effectively suppress both a pseudo color and color noise.Type: ApplicationFiled: November 2, 2011Publication date: August 29, 2013Applicant: CANON KABUSHIKI KAISHAInventor: Yuichi Hirai

Patent number: 7376277Abstract: Color image transform coding methods and apparatus which take advantage of redundant information which is normally present in the luminance and chrominance components of a color image are described. The transform coding method of the present invention, can normally provide increased compression and/or better image quality at a given coding data rate than conventional JPEG or JPEG 2000 coding which does not use the transform of the present invention as part of the color component coding process. These benefits are normally achieved without generating more coefficients than would be generated in the case of more conventional coding such as JPEG or JPEG 2000 coding. In fact, the transform of the present invention can be applied to increase the coding efficiency of coding systems which perform spatial transforms and modeling and entropy coding operations of the type normally used in JPEG and/or JPEG 2000 coding systems.Type: GrantFiled: June 15, 2004Date of Patent: May 20, 2008Assignee: Pegasus Imaging CorporationInventors: William Douglas Withers, Irina Popovici
