  • Patent number: 11636933
    Abstract: A system (100) includes an end point prediction engine (150) that predicts an end point (302) using a machine learning model (132) and one or more clinical report objects (152) for a patient, wherein the machine learning model inputs the one or more clinical report objects and outputs the predicted end point according to phrases or n-grams in the one or more clinical report objects. An end point visualization interface (160) visualizes the predicted end point (302) using a scorecard (162) or a timeline (164). An end point modeling engine (130) generates the machine learning model from training data that includes validated end points (122) and clinical report objects (116).

  • Patent number: 11409786
    Abstract: The present disclosure pertains to computer-assisted search of image slices. In some embodiments, an image slice having a detected finding (and representing a cross section of at least a portion of an individual) may be determined. A search space may be reduce to a subset of image slices respectively representing a cross section corresponding to the cross section represented by the determined image slice. The search space reduction may comprise filtering a set of image slices based on the cross section represented by the determined image slice. Image slice information related to the determined image slice and related one or more image slices (of the image slices subset) may be obtained based on the search space reduction. A determination of whether indications of the detected finding exist in the image slices (of the image slices subset) may be effectuated based on the image slice information.

  • Patent number: 10998096
    Abstract: A system and method are provided for enabling a user to annotate a medical image. A collection of key-value pairs is provided, in which a key represents an image-observable quantity and a value represents the value of the image-observable quantity. A collection of structured finding objects is provided, wherein each structured finding object represents a set of key-value pairs, each set of key-value pairs representing a different annotation of the medical image. The user is enabled to select one or more of the collection of key-value pairs, thereby obtaining a user-selected structured finding object which represents a preliminary annotation of the medical image by the user. At least one recommended structured finding object is selected by using the user-selected structured finding object as input to a probabilistic recommendation algorithm. Feedback is provided to the user on the basis of the recommended structured finding object. The annotation is well suited for, e.g.

  • Publication number: 20200176107
    Abstract: A device, system, and method optimizes image acquisition workflows. The method performed at a workflow server includes receiving data associated with previous image acquisition procedures that have been performed, the image acquisition procedures having respective image orders, the image orders having respective contexts, each of the image acquisition procedures having used at least one sequence defining settings to capture an image. The method includes determining at least one metric associated with a use of a first one of the at least one sequence for a first one of the contexts. The method includes generating a rule indicative of whether the first sequence is to be included or excluded for a subsequent image acquisition procedure having the first context based on the at least one metric.

  • Publication number: 20190355456
    Abstract: A system includes a ranking engine (110) and a user interface (130). The ranking engine receives a list (114) for a patient which includes a plurality of occurrences (210) and computes a relevance score for each occurrence (210) in the list. The computed relevance score is according to a relevance scheme (116) that maps relevance scores from a lexicon controlling the list to each of the plurality of occurrences. The user interface (130) displays the list on a display device (137) of a local computing device (140) ordered by a presented computed relevance score that includes the computed relevance score. Each displayed occurrence of the plurality of occurrences includes a feedback indicator (136). The user interface receives feedback comprising an input for one displayed occurrence of the plurality of occurrences according to the feedback indicator which indicates the one displayed occurrence is to be displayed higher or lower in the list than a current position. The input is a binary indicator.
