| Abstract: | phased delay and the space features of ultrasonic beams the interrelation between the direction of the neighbouring beam and delay is deyeloped and the useful features are found out. A new method of increasing frame frequency-simultaneous multi-beamforming is put forward to improve the qualities of the color ultrasonic imaging system. |
