PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic device, etc. in which regardless of a patient with an irregular heartbeat disease, for instance, having any disturbance in his heartbeat period or cycle, the device can timely present a three-dimensional region dynamic picture image obtained by synthesizing the same time phase data for every sub volume.SOLUTION: In an ultrasonic diagnostic device, while switching one sub volume to another at every heartbeat as an object for ultrasonic scanning, the collection of sub volume data is started after the passage of a certain time from a prescribed time phase, collected sub volume data are synthesized in diagnostic periods differing from one another, either a synchronized sub volume made of a plurality of sub volume data or the full volume data are generated. At least either the cyclic change in the subject heartbeat signals or the change in the number of the sub volume data collected in the preceding one diagnostic period is detected. Based on the detection results, sub volume data are synthesized to each other. |
