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: A medical image processing device of an embodiment includes processing circuitry. The processing circuitry is configured to acquire a contrast-enhanced image of a subject at least after a portal vein dominant phase among contrast-enhanced images of the subject to which a contrast medium has been administered in a process of reaching a post-vascular phase from an artery dominant phase via the portal vein dominant phase, and detect a site where the contrast medium has been washed out as a defective part in the contrast-enhanced image after the portal vein dominant phase.

Abstract: According to one embodiment, an ultrasonic diagnostic apparatus includes an ultrasonic probe and processing circuitry. The processing circuitry causes the ultrasonic probe to perform a first scan and second scan in a same scan sequence, wherein the first scan is for calculating a first index value based on a displacement of tissue by a shear wave that propagates through a living body, the second scan for calculating a second index value indicating an attenuation of a reflected wave signal of an ultrasonic wave applied into the living body. The processing circuitry generates a first image based on the first index value, and generates a second image based on the second index value. The processing circuitry causes a display to simultaneously display the first image and the second image.

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.
