中文摘要: 全聚焦成像算法是一种基于全矩阵数据处理的合成孔径成像技术,因其具有成像精度高等优点成为近年来的研究热点。与传统诊断设备相比,超声相控阵具有易于控制、操作简单、便于携带等特点。基于超声相控阵合成孔径技术,提出了基于全聚焦算法的骨折超声检测方法。Field Ⅱ仿真实验、钢板缺孔实验和骨板裂纹实验都成功地定位了缺陷位置,误差分别为0,2.67%,2.86%;骨板裂纹实验检测出骨板裂纹深度和宽度,误差分别为6.67%和5.33%。实验结果表明,该方法在临床骨折检测方面有很大的发展潜力。
Abstract:Total focusing method is a synthetic aperture imaging technology based on full matrix capture data processing.It has become a research hotspot in recent years because of its high imaging accuracy.Compared with traditional diagnostic equipment,ultrasonic phased array is easy to control,simple to operate and portable.Based on synthetic aperture technique of ultrasonic phased array,an ultrasonic fracture detection method based on total focusing method is proposed in this paper.Experiment of Field Ⅱ simulation,experiment of steel plate and experiment of bone crack all successfully located the defect position,and the position errors were 0%,2.67%,2.86% respectively.The crack depth and width of bone plate are also detected,and the errors are 6.67% and 5.33% respectively.The results suggest that this method has great potential in clinical fracture detection.
