Patent number: 11170900Abstract: The invention relates to search for cases in a database. According to the proposed method and apparatus, similarity matching is performed between an input case and a set of cases in an initial search to receive similar cases by using a given matching criterion. Then statistics on image and/or non-image-based features associated with the similar cases are calculated and presented to the user with the similar cases. In a search refinement the similar cases are refined by additional features that are determined by the user based on the statistics. The search refinement can be iterative depending on the user's need.Type: GrantFiled: December 10, 2008Date of Patent: November 9, 2021Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Lilla Boroczky, Lalitha Agnihotri, Luyin Zhao, Michael Chun-chieh Lee

Patent number: 9792414Abstract: This invention relates to a method and device for case-based decision support. It proposes that a case-based decision support system is trained on inputs from several radiologists in order to have a “baseline” system, and then the system provides an option to a radiologist to refine the baseline system based on his/her inputs which either refine weights of features for similarity distance computation directly or provide new similarity ground truth clusters. By enabling modifying the similarity distance computation based on user inputs, this invention adapts similarity ground truth to different users with different experience and/or different opinions.Type: GrantFiled: December 11, 2008Date of Patent: October 17, 2017Assignee: Koninklijke Philips N.V.Inventors: Lalitha Agnihotri, Lilla Boroczky, Luyin Zhao, Michael Chun-chieh Lee

Patent number: 8265355Abstract: A method for segmenting regions within a medical image includes evaluating a set of candidate segmentations generated from an initial segmentation. Based on distance calculations for each candidate using derivative segmentations, the best candidate is recommended to clinician if it is better than the initial segmentation. This recommender realizes a most stable segmentation that will benefit follow-up computer aided diagnosis (i.e. classifying lesion to benign/malignant).Type: GrantFiled: November 18, 2005Date of Patent: September 11, 2012Assignee: Koninklijke Philips Electronics N.V.Inventors: Luyin Zhao, Kwok Pun Lee

Patent number: 8185511Abstract: Optimizing example-based computer-aided diagnosis (CADx) is accomplished by clustering volumes-of-interest (VOIs) (116) in a database (120) into respective clusters according to subjective assessment of similarity (S220). An optimal set of volume-of-interest (VOI) features is then selected for fetching examples such that objective assessment of similarity, based on the selected features, clusters, in a feature space, the database VOIs so as to conform to the subjectively-based clustering (S230). The fetched examples are displayed alongside the VOI to be diagnosed for comparison by the clinician. Preferably, the displayed example is user-selectable for further display of prognosis, therapy information, follow up information, current status, and/or clinical information retrieved from an electronic medical record (S260).Type: GrantFiled: June 15, 2007Date of Patent: May 22, 2012Assignee: Koninklijke Philips Electronics N.V.Inventors: Lalitha Agnihorti, Lilla Boroczky, Luyin Zhao
