  • Publication number: 20250017570
    Abstract: A log management unit creates a log in which an operation of an ultrasound diagnostic apparatus is recorded. A model operation management unit saves an analysis target image input to an image analysis model and an analysis result of the image analysis model for each operation of the image analysis model. In a case where a specific model operation record in the log is selected, the report creation unit creates a model operation report. The model operation report includes the analysis target image input to the image analysis model and the analysis result of the image analysis model.

  • Publication number: 20240428409
    Abstract: A recording unit records an analysis operation of an image analysis model and records an adoption/non-adoption of an analysis result. As a result, a log is generated. A calculation unit calculates an adoption rate as a score indicating performance of the image analysis model based on the log. A generation unit generates, in a case where the adoption rate is smaller than a threshold value, a reference image for notifying an examiner of such a situation.

  • Publication number: 20210212660
    Abstract: An ultrasound diagnosis apparatus includes a processor for performing grouping processing and representative frame selection processing on a plurality of ultrasound frames that are sequentially generated with the passage of time. The grouping processing is processing that identifies a group of interest that is composed of a plurality of frames that satisfy at least one predetermined condition of interest. The representative frame selection processing is processing that selects a representative frame from among the plurality of frames that constitute the group of interest. The at least one predetermined condition of interest includes a condition that each of the plurality of frames includes data indicating a specific region identified by region recognition processing in which a characteristic region in an image is recognized as the specific region. The representative frame selection processing includes processing that selects the representative frame based on geometrical properties of the specific regions.

  • Patent number: 8357897
    Abstract: A charged particle beam device enabling prevention of degradation of reproducibility of measurement caused by an increase of the beam diameter attributed to an image shift and having a function of dealing with device-to-device variation. The charged particle beam device is used for measuring the dimensions of a pattern on a specimen using a line profile obtained by detecting secondary charged particles emitted from the specimen when the specimen is scanned with a primary charged particle beam converged on the specimen. A lookup table in which the position of image shift and the variation of the beam diameter are associated is prepared in advance by actual measurement or calculation and registered. When the dimensions are measured, image processing is carried out so as to correct the line profile for the variation of the beam diameter while the lookup table is referenced, and thereby the situation where the beam diameter is effectively equal is produced irrespective of the position of the image shift.
