摘　　要：超声相控阵全聚焦成像算法作为一种后处理成像技术,虽然具有成像精度高、灵活性好的优势,但由于数据量大、计算时间长等问题,该项技术的实际工业应用受到了极大限制。针对该算法的不足,这里提出了基于均匀稀疏矩阵的全聚焦成像算法,通过减少矩阵数据量来提高成像效率。结果表明:相较于传统全聚焦成像算法,基于均匀稀疏矩阵的全聚焦成像算法极大的压缩了数据规模,计算速度同比提高约38%,为全聚焦快速成像提供了一种参考方法。As a post-processing imaging technique,ultrasonic phased array total-focus imaging method has the advantages of high imaging accuracy and good flexibility.Due to the large amount of data and long calculation time,the practical industrial application of this technology has been greatly restricted.Aiming at the shortcomings of the metod,in this paper,a total focus im⁃aging method based on uniform sparse Matrix was presented by reducing the amount of matrix data,which can improve the imag⁃ing efficiency.The results show that compared with the traditional ftotal-focus imaging method,the size of the data greatly was reduced by the total-focus imaging method based on uniform sparse Matrix,and the computing speed was improved about 38%,which provides a reference method for total-focus imaging.
