Abstract: According to one embodiment, an apparatus includes an acquisition unit and a generation unit. The acquisition unit specifies the cycle of pulses in a part that performs periodic motion based on blood flow information in the part. The generation unit rearranges a plurality of two-dimensional images of the part based on the cycle to generate a three-dimensional image.

Abstract: In one embodiment, an ultrasonic diagnostic apparatus includes: a display; a probe; and processing circuitry. The processing circuitry acquires an appearance image of an object that is scheduled to undergo dialysis, generates a 3D image from an echo signal acquired by the probe, the 3D image containing a plurality of frame images depicting inside of the object and positional information of each of the plurality of frame images, extracts a blood-vessel image depicting a blood vessel inside the object from the 3D image, generates a composite image of the appearance image and the blood-vessel image by aligning the appearance image and the blood-vessel image, and causes the display to display the composite image.

Abstract: According to one embodiment, a medical information processing apparatus includes processing circuitry. The processing circuitry determines whether or not a plurality of ultrasonic images are images collected by a stress echocardiography method. The processing circuitry adds attribute information to each of the ultrasonic images if it is determined that the ultrasonic images are images collected by the stress echocardiography method, the attribute information concerning at least one of a stress state of a subject and a slice of the ultrasonic image.

Abstract: The X-ray diagnostic apparatus according to a present embodiment includes processing circuitry. The processing circuitry is configured to: generate an X-ray image of an object by irradiating the object with X-rays; acquire an evaluation result of at least one of elasticity evaluation of a blood vessel of the object and thickness evaluation of a wall of the blood vessel of the object; generate a superimposed image in which the evaluation result is superimposed on the X-ray image; and display the superimposed image on a display.
