Patent number: 11915823Abstract: In some aspects, the described systems and methods provide for validating performance of a model trained on a plurality of annotated pathology images. A pathology image is accessed. Frames are generated using the pathology image. Each frame in the set includes a distinct portion of the pathology image. Reference annotations are received from one or more users. The reference annotations describe at least one of a plurality of tissue or cellular characteristic categories for one or more frames in the set. Each frame in the set is processed using the trained model to generate model predictions. The model predictions describe at least one of the tissue or cellular characteristic categories for the processed frame. Performance of the trained model is validated based on determining a degree of association between the reference annotations and the model predictions for each frame and/or across all frames in the set of frames.Type: GrantFiled: November 10, 2022Date of Patent: February 27, 2024Assignee: PathAI, Inc.Inventors: Harsha Vardhan Pokkalla, Hunter L. Elliott, Dayong Wang, Benjamin P. Glass, Ilan N. Wapinski, Jennifer K. Kerner, Andrew H. Beck, Aditya Khosla, Sai Chowdary Gullapally, Ramprakash Srinivasan

Patent number: 11908139Abstract: In some aspects, the described systems and methods provide for a method for training a statistical model to predict tissue characteristics for a pathology image. The method includes accessing annotated pathology images. Each of the images includes an annotation describing a tissue characteristic category for a portion of the image. A set of training patches and a corresponding set of annotations are defined using an annotated pathology image. Each of the training patches in the set includes values obtained from a respective subset of pixels in the annotated pathology image and is associated with a corresponding patch annotation determined based on an annotation associated with the respective subset of pixels. The statistical model is trained based on the set of training patches and the corresponding set of patch annotations. The trained statistical model is stored on at least one storage device.Type: GrantFiled: July 13, 2023Date of Patent: February 20, 2024Assignee: PathAI, Inc.Inventors: Andrew H. Beck, Aditya Khosla

Patent number: 11657505Abstract: In some aspects, the described systems and methods provide for a method for training a model to predict survival time for a patient. The method includes accessing annotated pathology images associated with a first group of patients in a clinical trial. Each of the annotated pathology images is associated with survival data for a respective patient. Each of the annotated pathology images includes an annotation describing a tissue characteristic category for a portion of the image. Values for one or more features are extracted from each of the annotated pathology images. A model is trained based on the survival data and the extracted values for the features. The trained model is stored on a storage device.Type: GrantFiled: May 24, 2021Date of Patent: May 23, 2023Assignee: PathAI, Inc.Inventors: Andrew H. Beck, Aditya Khosla

Patent number: 11080855Abstract: In some aspects, the described systems and methods provide for a method for predicting tissue characteristics for a pathology image. A statistical model trained on multiple annotated pathology images is used. Each of the training pathology images includes an annotation describing tissue characteristics for one or more portions of the image. The method includes accessing a pathology image for predicting tissue characteristics. A trained statistical model is retrieved from a storage device. A set of patches is defined from the pathology image. Each of the patches in the set includes a subset of pixels from the corresponding pathology image. The set of patches is processed using the trained statistical model to predict respective annotations for each patch in the set. The predicted annotations are stored on the storage device.Type: GrantFiled: June 6, 2018Date of Patent: August 3, 2021Assignee: Path AI, Inc.Inventors: Andrew H. Beck, Aditya Khosla
