    Abstract: According to one embodiment an ultrasound diagnostic apparatus includes processing circuitry. The processing circuitry acquires first ultrasonic image data of a first mode, estimates a position of an examination target included in the first ultrasonic image data by applying a trained model to the first ultrasonic image data and output an estimation result, calculates a coordinate of a region of interest corresponding to a second mode different from the first mode based on the estimation result and information on the second mode, and displays the region of interest on second ultrasonic image data of the second mode based on the coordinate.

    Abstract: According to one embodiment, an analysis apparatus includes processing circuitry. The processing circuitry configured to generate a harmonic signal and a fundamental wave signal based on a reception signal that is collected by an ultrasound probe, the harmonic signal corresponding to a harmonic component of a reflected wave of a ultrasound generated in the subject, the fundamental wave signal corresponding to a fundamental wave component of the reflected wave, calculate a first index value indicating tissue properties of the subject based on the harmonic signal, and calculate a second index value indicating the tissue properties based on the fundamental wave signal, and display an analysis result based on the first index value and the second index value.

    Abstract: An analyzing apparatus according to an embodiment includes processing circuitry. The processing circuitry acquires a plurality of time-series medical images. The processing circuitry calculates, for each of image pairs each formed of two medical images included in the medical images, a first index value indicating similarity between image signals in the two medical images. The processing circuitry also calculates, on the basis of a plurality of the first index values calculated for the respective image pairs, a second index value corresponding to a statistical value in a time direction of the first index values.

    Abstract: An ultrasound diagnosis apparatus according to an embodiment includes processing circuitry. The processing circuitry is configured to generate contrast image data on the basis of a contrast signal acquired from an examined subject to whom a contrast agent is administered. The processing circuitry is configured to generate blood flow image data on the basis of a blood flow signal estimated by performing a filtering process on the contrast signal. The processing circuitry is configured to output information indicating a region where the contrast agent is stagnant within a region of interest, on the basis of the contrast image data and the blood flow image data.

    Abstract: The medical image processing apparatus according to the present embodiment includes processing circuitry. The processing circuitry is configured to acquire contrast image data generated by imaging a subject. The processing circuitry is configured to input the acquired contrast image data to a learned model to generate a time phase data classified according to a contrast state of a lesion area with a contrast agent included in the acquired contrast image data, the learned model being for generating the time phase data based on the acquired contrast image data.
