An ultrasonic diagnostic apparatus has a unit which sets a display region for displaying a 3D image, a unit which transmits and receives ultrasound waves, a unit which generates volume data, a unit, on the basis of the volume data, which sets an analysis region, a unit, on the basis of the data on the analysis region contained in the volume data, which analyzes a fluctuations in signal intensity over time, a unit, on the basis of the analysis result, which calculates a cardiac cycle, a unit, on the basis of the cardiac cycle and the volume data, which generates data set constructed by data with substantially equal cardiac cycle, and generates data sets corresponding to a plurality of cardiac cycles, and a unit which displays the 3D images based on the data sets as a moving image.

Ultrasonic diagnostic apparatus and controlling method of ultrasonic diagnostic apparatus

In one embodiment, an ultrasonic diagnostic apparatus includes an image creating unit, an image-creation control unit and a display control unit. The image creating unit creates an ultrasound image from data created by adding a reflected wave signal of an ultrasound wave transmitted to an imaging target portion of a subject by using a reception delay time calculated from a set sound velocity set as a sound velocity in the imaging target portion. The image-creation control unit switches a set sound velocity set at a present moment in a variable range, and controls the image creating unit so as to create a plurality of ultrasound images each using a reception delay time corresponding to each of the set sound velocities to be switched. The display control unit controls display such that the ultrasound images created are displayed on a certain display unit.
