Abstract: The ultrasonic diagnostic apparatus according to the present embodiment includes processing circuitry. The processing circuitry is configured to determine a scan region of an ultrasonic wave according to a scan target. The processing circuitry is configured to set a pulse repetition frequency for each raster of rasters so as to correspond to the scan region. The processing circuitry is configured to control a scan performance according to the pulse repetition frequency.

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.

Abstract: An ultrasound diagnosis apparatus according to an embodiment includes processing circuitry and a display. The processing circuitry generates, from ultrasound data, pieces of low and high frequency data corresponding to resolutions of gradual degrees, extracts pieces of negative high frequency data over a range of predetermined resolutions, from the pieces of high frequency data, restores the resolution of first addition data so as to be equal to the resolution of the ultrasound data before reduction, the first addition data being obtained by adding up the pieces of negative high frequency data while causing resolutions to match over the range of the predetermined resolutions, and generates a combined image on the basis of the restored first addition data and the ultrasound data. The display displays the combined image.
