Abstract
Ultrasonic imaging system with a linear array having several transducer elements of which a respective group of commonly controlled transducer elements forms one beam aperture and to which one transmitting system and one receiving system is allocated. A delay time is digitally set for each transducer element of the beam aperture and triggered by means of a starting pulse, and the echo signals of the transducer elements of the beam aperture are added and phase delayed by the software. In this manner, an ultrasonic imaging system for high ultrasonic frequencies, particularly at least in the order of 30 MHz is achieved in which transmitting and receiving lens can be created independently of one another in the computer by changing the software, while the hardware remains unchanged.
