Abstract
In an exemplary embodiment, an ultrasonic array has an installation for dynamic focusing at least in the transmitting mode. It is the object of the disclosure to avoid excessively great time loss, and yet to permit dynamic focusing also in the transmitting mode. This object is achieved in that, in the case of a specifiable number of depth regions (with a respective fixed focusing in each depth region) preferably associated with each scanning line of the ultrasonic scanning, the transmitting/receiving cycle for each fixed focusing is progressively introduced in such a manner that, for every depth region of each such scanning line, transmission is effected at such a time-point which immediately follows, for example, that time interval in which echo information was received from the chronologically prior-scanned depth region for such scanning line. More generally, the second ultrasonic pulse for a given scanning line occurs while echo signals due to the first pulse are still returning from the depth extent of the body which is under examination.
