Ultrasonic diagnostic apparatus

An ultrasonic diagnostic apparatus comprising:na probe including a transducer unit including a plurality of transducers which are arrayed in a first direction, transmit ultrasonic waves and receive echo signals, and a moving mechanism for continuously moving the transducer unit in a second direction crossing the first direction;a control unit which controls the moving mechanism to continuously move the transducer unit in the second direction;a transmission unit which causes the transducer unit to generate ultrasonic waves;a signal generation unit which generates a plurality of actual measurement scan line signals by delaying and adding a plurality of echo signals from the transducer unit;a detection unit which detects positions of the plurality of actual measurement scan line signals;a determination unit which determines positions of a plurality of mathematical scan line signals regarding a plurality of mathematical electronic scan planes based on the positions of the plurality of actual measurement scan line signals;a signal calculation unit which calculates a plurality of mathematical scan line signals from the plurality of actual measurement scan line signals based on distances between the detected positions of the plurality of actual measurement scan line signals and the determined positions of the plurality of mathematical scan line signals; andan image generation unit which generates multislice tomograms on the basis of the plurality of calculated mathematical scan line signals.

An ultrasonic diagnostic apparatus comprising:na storage unit which stores a plurality of actual measurement scan line signals constituting a plurality of actual measurement electronic scan planes;a determination unit which determines positions of a plurality of mathematical scan line signals regarding a plurality of mathematical electronic scan planes perpendicular to a moving direction of an ultrasonic probe;a signal calculation unit which calculates a plurality of mathematical scan line signals from the plurality of actual measurement scan line signals based on distances between positions of the plurality of actual measurement scan line signals and positions of the plurality of mathematical scan line signals; andan image generation unit which generates multislice tomograms on the basis of the plurality of calculated mathematical scan line signals.
