Abstract: In one embodiment, an ultrasonic diagnostic apparatus includes an ultrasonic probe and a a main body. The ultrasonic probe includes at least a plurality of ultrasonic transducers arranged in an array and an ultrasonic lens. The main body inspects the ultrasonic probe by using a reflected signal from an interface between the ultrasonic lens and air, and includes inspection processing circuitry. The inspection processing circuitry is configured to: sequentially select an ultrasonic transducer to be inspected from the plurality of ultrasonic transducers one by one in such a manner that any two ultrasonic transducers being continuously selected are not spatially adjacent but are separated by a predetermined separation distance; cause the selected ultrasonic transducer to transmit an ultrasonic pulse; and sequentially inspect each of the plurality of ultrasonic transducers by acquiring a reflected signal responding to transmission of the ultrasonic pulse from the interface.

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: According to one embodiment, an ultrasonic diagnostic apparatus includes processing circuitry. The processing circuitry acquires position information relating to an ultrasonic probe and an ultrasonic image. The processing circuitry acquires ultrasonic image data which is obtained by transmission and reception of ultrasonic from the ultrasonic probe at a position where the position information is acquired, the ultrasonic image data being associated with the position information. The processing circuitry executes associating between a first coordinate system relating to the position information and a second coordinate system relating to medical image data. The processing circuitry executes image alignment between an ultrasonic image based on the associated ultrasonic image data and a medical image based on the medical image data.

Abstract: An ultrasonic diagnostic device includes an ultrasonic probe and processing circuitry. The probe conducts ultrasonic scanning on a three-dimensional area of a subject and receives a reflected wave from the subject. The circuitry acquires the correspondence relation between a position in ultrasonic image data on the three-dimensional area based on the reflected wave and a position in volume data on the subject captured by a different medical-image diagnostic device. The circuitry receives, from an operator, an operation to set a position marker, which indicates the position at which blood-flow information is extracted, on a scan area of the ultrasonic image data. The circuitry causes the image generated during a rendering process on the ultrasonic image data to be displayed and causes the position marker to be displayed at a corresponding position on a display image based on at least the volume data in accordance with the correspondence relation.
