摘要
文中提出了一种基于波达方向函数优化的超声合成孔径成像优化方法,来提高超声检测透射成像深度和抑制表面类噪声信号,并基于Field II进行仿真验证。与传统超声合成孔径成像进行比较,结果表明,该方法明显提高了成像深度,抑制了表面类噪声信号。
To improve the transmission depth and depress the noise-like signal of surface,an optimal approach of ultrasonic synthetic aperture imaging based on the direction of arrival function is proposed and it is verified based on the simulation of Field II. Compared with the approach of conventional ultrasonic synthetic aperture imaging,it shows that this work obviously improves the transmission depth and depresses the noise-like signal.
