Pulse-echo ultrasonic wave-energy imaging system incorporating high-angular velocity oscillated transducer |
摘要 |
Transducer completely immersed in ultrasonic propagating liquid can be oscillated back and forth at a high rate, without producing significant turbulence in liquid, if oscillation velocity varies as a predetermined smooth continuous function of time.
