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.

Abstract: According to one embodiment, an ultrasound image diagnosis apparatus includes a display and a control circuit. The display is con figured to display an ultrasound image generated based on an echo signal of ultrasound waves transmitted to a site to be diagnosed. The control circuit is configured to measure a measurement target on the ultrasound image of the site to be diagnosed displayed on the display. The control circuit performs a definition function to define the distance between a caliper used to measure the measurement target and a guide used to arrange the caliper at the position of the measurement target, a display control function to control the display of the caliper and the guide arranged to be separated by the distance defined such that the caliper and the guide are integrally movable on the ultrasound image, and a measurement function to measure the measurement target using the caliper.
