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: 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: An ultrasound diagnostic apparatus according to an embodiment includes image processing circuitry. The image processing circuitry acquires, based on a result of ultrasound scanning performed on a subject, blood flow information including a value that indicates a blood flow at each position within the subject and tissue property information including a value that indicates tissue properties at each position within the subject. The image processing circuitry generates a first image in which a difference in value in the blood flow information is represented by at least a difference in hue and a second image in which a difference in value in the tissue property information is represented by a difference other than the difference in hue. The image processing circuitry generates a combined image by combining the first image and the second image.
