When the detected lesion candidate is an exclusion target, a mark display control unit restricts display of a mark for indicating a lesion candidate.

A reception signal output by an ultrasonic probe that has received an ultrasonic wave from a subject is received, and an ultrasonic image is generated based on the reception signal. A trained neural network receives the reception signal or the ultrasonic image, and outputs an estimated reception signal or an estimated ultrasonic image. A validity information generation unit generates information indicating validity of the estimated reception signal or the estimated ultrasonic image by using one or more of the reception signal, the ultrasonic image, the estimated reception signal, the estimated ultrasonic image, and output of an intermediate layer of the neural network.

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.

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.
