ABSTRACT:
An ultra sound examining device operating according to the impulse echo process and used for medical purposes comprises an ultra sound sending-receiving system the sender of which transmits ultra sound impulses in predetermined time intervals into the object being examined through a precursor stretch connected in front of the system, for example, water precursor stretch. There is also an echo impulse representing device operated depending upon the transmitted impulses which represents echo impulses of each transmitted impulse received by the receiver one after the other corresponding to the time sequence of their appearance. The invention is particularly characterized in that the time interval between two succesive transmitted impulses of the ultra sound sender has a value which is smaller than the sum of the precursor time of the ultra sound impulses in the precursor stretch and the representation time of the echo impulses on the representing device. However, even the smallest value is not less than the representation time.
