Abstract: According to one embodiment, an ultrasound diagnostic apparatus includes an ultrasound probe and processing circuitry. The ultrasound probe is adapted to be applied on a surface of a subject. The ultrasound probe performs ultrasound scanning for a scan region in the subject. The processing circuitry analyzes, among a result of the ultrasound scanning, a part corresponding to a central portion of the scan region to calculate a distance between a blood vessel in the central portion and the surface. The processing circuitry causes a display to display the distance, a value based on the distance, or both the distance and the value.

Abstract: According to one embodiment, an ultrasonic diagnostic apparatus includes processing circuitry. The processing circuitry acquires first echo data in a first mode, and acquires second echo data in a second mode. The processing circuitry sequentially generates a first image including a B-mode image based on the first echo data in the first mode, and sequentially generates a second image not including a B-mode image based on the second echo data in the second mode. The processing circuitry sequentially generates a third image from pre-acquired volume data. The processing circuitry directs a display to sequentially display the first image and the third image in the first mode, and to sequentially display the second image and the third image in the second mode.

Abstract: An ultrasonic diagnosis apparatus according to an embodiment includes a transmission unit, a reception unit, a generator, and a display controller. The transmission unit causes an ultrasonic probe to transmit a displacement-producing ultrasonic wave and causes the probe to transmit a displacement-observing ultrasonic wave. The reception unit generates reflected-wave data based on a reflected wave received by the probe. The generator calculates displacement at each of a plurality of positions in the scan area over a plurality of time phases, based on the reflected-wave data, determines a time phase when the calculated displacement is substantially maximum, for each of the positions, and generates image data representing positions where the determined time phases are substantially the same as each other, among the positions. The display controller superimposes an image based on the image data on a medical image corresponding to an area including the scan area.
