Publication number: 20220260825Abstract: A method of analyzing a plurality of histology slides is provided, wherein possible artefacts are detected at an early stage. This is achieved by including a preliminary imaging and image analysis step in the process flow; the step being executed preferably before any diagnostic assessment e.g. image analysis or manual reading is performed by a pathologist or a lab technician. Accordingly, the histology slides reaching the expert for image analysis are of a higher quality, since the slides are ideally free of artefacts. The method thus saves valuable time for the pathologist, since only artefact-free slides will be subject to a detailed analysis. Furthermore, the method minimizes the risk of misinterpretations leading to potentially false diagnoses. A deep learning model, is also disclosed, which is capable of automatically determining whether histopathological images are suitable for diagnostic and/or research assessment. A training of the deep learning model is also disclosed.Type: ApplicationFiled: June 26, 2020Publication date: August 18, 2022Inventors: Michael Grunkin, Johan Doré Hansen, Jeppe Thagaard

Patent number: 10209165Abstract: The quality of staining histological specimens has an impact on the histological assessment of the specimen. One of the causes for variability in the accuracy is the variations in the staining of the specimens to be tested in the working laboratories. The present invention provides a method for assessing the staining quality in a working laboratory and providing a quantitative quality measure for the staining quality. Thereby, it is possible for each working laboratory to evaluate their staining quality and to get feedback of how to improve the quality. The invention further relates to a system and a software program for carrying out the method.Type: GrantFiled: March 9, 2015Date of Patent: February 19, 2019Assignee: Visiopharm A/SInventors: Michael Grunkin, Johan Doré Hansen

Patent number: 9697582Abstract: Disclosed is a method and a system for obtaining and analyzing image pairs, obtained as sections of specimen. The invention facilitates registration of two corresponding images, one from each section of the specimen. The invention includes performing a registration process of the two images thereby obtaining a mathematical transformation rule and afterwards using said transformation rule for each image field identified in one image allowing that the corresponding image field in the other image may be identified as well. After the corresponding image pairs have been obtained using the method of the present invention, the sections can be assessed, such as by identifying the counting events for at least one type of object on the image fields within at least one corresponding image pair, optionally using automatic means.Type: GrantFiled: March 24, 2014Date of Patent: July 4, 2017Assignee: Visiopharm A/SInventors: Michael Grunkin, Steen T.
