  • Patent number: 11923072
    Abstract: An image diagnosis supporting device includes a model reader that reads an image diagnostic model that outputs a diagnostic result for a diagnostic image that is an input medical image, a storage unit that stores facility data that is a plurality of medical images associated with diagnostic results held in a facility, and an adjuster that adjusts, based on the facility data, the image diagnostic model or the diagnostic image input to the image diagnostic model.

  • Publication number: 20230154584
    Abstract: A computer system manages a first model calculating an output value, using time-series data including a value related to an intervention carried out on a person, a second model that calculates a feature by mapping an output value from the first model onto a feature space, and a third model that outputs a predicted value of an effect of an intervention, from the feature. The time-series data includes a time at which the intervention is carried out, factors indicating a state of the person, and a type and a degree of the intervention. The computer system calculates a predicted value of the continuous intervention corresponding to the time-series data, using the first, second, and third models. The second model maps an output value from the first model onto the feature space so that a difference in distribution of data strings used in machine learning reduces in the feature space.

  • Patent number: 11049255
    Abstract: Volume data is used for extracting a contour of a measurement object and measurement information describing anatomical structure useful for diagnosis is acquired from the contour. When volume data of a subject is inputted (S301), an image processing device detects feature points in the volume data (S302); detects contours of a plurality of parts in the volume data based on the detected feature points and anatomical definitions (S303); and optimizes boundary lines defining contours of parts contacting each other, out of the detected plural parts, so as to combine together the optimized contours of the plural parts for creating a contour of the measurement object (S304). Measurements are taken on diagnostic items useful for diagnosis based on the created contour (S305); and the acquired measurement information is outputted as measurement results (S306) which are displayed at a display.

  • Patent number: 10674994
    Abstract: A standard view which satisfies recommendations defined in a guideline on acquisition of standard views is extracted at a time of using information about defined landmarks and a defined landmark geometry in the three-dimensional information. When 3D volume data on a subject is input (S301), an image processing apparatus extracts a landmark geometry including landmarks contained in the 3D volume data on the basis of a position relationship among the landmarks (S302), determines a standard view of the 3D volume data using the landmark geometry and a position relationship that satisfies recommendations in a guideline on the acquisition of the standard views (S303), and outputs the obtained standard view (S304) to display the standard view on a display.
