Abstract

一种超声声速搜索方法和超声成像系统，所述方法包括：生成超声图像，并确定其中的待处理区域；获取通过第一声速和第二声速分别对超声回波信号进行处理得到的待处理区域的第一超声图像及其第一清晰度以及第二超声图像及其第二清晰度，第二声速大于第一声速；根据第一清晰度和第二清晰度的变化情况确定第三声速；采用第三声速对所述超声回波信号进行处理，获得待处理区域的第三超声图像及其第三清晰度；当第三清晰度低于第一清晰度或第二清晰度时，确定二者中较大值对应的声速为待处理区域的最佳声速；当第三清晰度高于第一清晰度和第二清晰度时，根据二者中较大值与第三清晰度的变化情况确定第四声速。本方案提高了声速搜索的效率。
