本文讨论了改进的医用B超线阵扫描探头在工业无损检测中的应用．在合成孔径聚焦技术（SAFT）基础上提出了改进方法，在探元响应带宽较窄的情况下可获得较高信噪比的成像结果．文中介绍了成像系统，实验方法，并给出了一些实验结果．
This article discusses the application of the improved medical B-line scanning probe in industrial non-destructive testing. Based on the synthetic aperture focusing technique (SAFT), an improved method is proposed, which can obtain the imaging results with high signal-to-noise ratio when the probe response bandwidth is narrow. In this paper, the imaging system and experimental methods are introduced, and some experimental results are given.
