PROBLEM TO BE SOLVED: To provide a system and method for acquiring ultrasonic data at a certain acquisition speed and displaying at least part of the ultrasonic data at a display speed slower than the acquisition speed. SOLUTION: Ultrasonic data are continuously acquired and stored at a frame rate faster than a recognition speed of people's eyes, and at least part of the acquired ultrasonic data is displayed at a frame rate recognizable by a people. The acquisition and display of the data are synchronized from time to time when a condition for synchronization is satisfied. The condition for synchronization relates to a triggering event produced, for example, by a physiological phenomenon, detected with prescribed intervals of time or for example, in the ECG trace, or a triggering event through the triggering produced by the triggering event. Therefore, the acquired ultrasonic data, maintaining the realtime synchronism, are displayed at a display speed slower than the acquisition speed, or preferably, slower than the maximum recognition speed of people's eyes.
