摘　　要：对高帧率超声成像方法进行综述,介绍基于加权处理的高帧率成像方法、改进的高帧率超声成像方法、基于方波加权的高帧率成像方法和其他形式的高帧率成像方法,还分析了高帧率成像方法中的阵元数量、图像质量与帧率等问题.In this paper, the high frame rate ultrasound imaging methods were reviewed. The high frame rate imaging method with aperture weighting, extended high frame rate imaging method, high frame rate imaging method with square wave aperture weighting, and other methods were introduced. Besides, the problems of the number of elements and the relationship between imaging quality and frame rate were analyzed.
