中文摘要: |
文章通过仔细分析相控延时及超声波束的空间特征,导出了相邻波束指向与延时之间的相互关系;找出了其中的规律性及可用特征.提出一种提高帧频的新方法:多波束同时合成法,从而能有效地改善彩色超声成像质量. |
英文摘要: |
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. |
