The layer images made during one cardiac cycle with the image repetition rate of the ultrasonic diagnostic device (8) are stored in a buffer store (34) and transferred to a main store (48) with the aid of a selection stage (49) to generate three-dimensional sets of images only when a locating device (13), and ECG device (24) and a respiration detector (54) generate release signals which are allocated to a constant spatial probe position, a constant R-R interval distance and a constant respiratory state. The content of the main store (48) is evaluated with the aid of an image processing system (56), whereby sectional images may be calculated, especially for any sectional plane, and displayed on a monitor (31).
