Patent number: 11699508Abstract: Systems and methods for developing a classification model for classifying medical reports, such as radiology reports. One method includes selecting, from a corpus of reports, a training set and a testing set, assigning labels of a modality and an anatomical focus to the reports in both sets, and extracting a sparse representation matrix for each set based on features in the training set. The method also includes learning, with one or more electronic processors, a correlation between the features of the training set and the corresponding labels using a machine learning classifier, thereby building a classification model and testing the classification model on the reports in the testing set for accuracy using the sparse representation matrix of the testing set. The method further includes predicting, with the classification model, labels of an anatomical focus and a modality for remaining reports in the corpus not included in the sets.Type: GrantFiled: December 2, 2019Date of Patent: July 11, 2023Assignee: MERATIVE US L.P.Inventors: Marina Bendersky, Tanveer Fathima Syeda-Mahmood, Joy Tzung-yu Wu

Patent number: 11416772Abstract: Embodiments of the present disclosure include a computer-implemented method, a system, and a computer program product for integrating bottom-up segmentation techniques into a semi-supervised image segmentation machine learning model. The computer implemented method includes training a machine learning model with a labeled dataset. The labeled dataset includes ground truth segmentation labels for each sample in the labeled dataset. The computer implemented method also includes generating a pseudo labeled dataset by applying an unlabeled dataset to the machine learning model using a top-down segmentation grouping rule. The computer implemented method further includes evaluating the pseudo labeled dataset using a bottom-up segmentation grouping rule to produce evaluation results, combining the pseudo labeled dataset with the second pseudo labeled dataset into a training dataset, and then retraining the machine learning model with the training dataset.Type: GrantFiled: December 2, 2019Date of Patent: August 16, 2022Assignee: International Business Machines CorporationInventors: Hongzhi Wang, Alexandros Karargyris, Tanveer Fathima Syeda-Mahmood, Joy Tzung-yu Wu

Patent number: 11282601Abstract: Mechanisms are provided for automatically annotating input images with bounding region annotations and corresponding anomaly labels. The mechanisms segment an input image to generate a mask corresponding to recognized internal structures of a subject. A template data structure is generated that specifies standardized internal structure zones of the subject. The mechanisms register the mask with the template data structure to generate a template registered mask identifying standardized internal structure zones present within the mask, and generate bounding region annotations for each standardized internal structure zone of the template registered mask. The bounding region annotations are correlated with labels indicating whether or not the bounding region comprises an anomaly in the input image based on an analysis of a received natural language text description of the input image. The bounding region annotations and labels are stored in association with the input image.Type: GrantFiled: April 6, 2020Date of Patent: March 22, 2022Assignee: International Business Machines CorporationInventors: Joy Tzung-yu Wu, Yaniv Gur, Alexandros Karargyris, Tanveer Fathima Syeda-Mahmood

Patent number: 11246539Abstract: A system for automated detection and type classification of central venous catheters. The system includes an electronic processor that is configured to, based on an image, generate a segmentation of a potential central venous catheter using a segmentation method and extract, from the segmentation, one or more image features associated with the potential central venous catheter. The electronic processor is also configured to, based on the one or more image features, determine, using a first classifier, whether the image includes a central venous catheters and determine, using a second classifier, a type of central venous catheter included in the image.Type: GrantFiled: October 11, 2019Date of Patent: February 15, 2022Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Vaishnavi Subramanian, Hongzhi Wang, Tanveer Syeda-Mahmood, Joy Tzung-yu Wu, Chun Lok Wong

Patent number: 11244755Abstract: Mechanisms are provided to implement an automated medical imaging report generator which receives an input medical image and inputs the input medical image into a machine learning (ML) computer model trained to predict finding labels based on patterns of image features extracted from the medical image. The ML computer model generates a prediction of a finding label applicable to the input medical image in terms of a finding label prediction output vector. Based on the finding label prediction output vector, a lookup operation is performed, in a medical report database of previously processed medical imaging report data structures, to find a matching medical imaging report data structure corresponding to the finding label. An output medical imaging report is generated for the input medical image based on natural language content of the matching medical imaging report data structure.Type: GrantFiled: October 2, 2020Date of Patent: February 8, 2022Assignee: International Business Machines CorporationInventors: Tanveer Syeda-Mahmood, Chun Lok Wong, Joy Tzung-yu Wu, Yaniv Gur, Anup Pillai, Ashutosh Jadhav, Satyananda Kashyap, Mehdi Moradi, Alexandros Karargyris, Hongzhi Wang
