Abstract

一种超声弹性测量显示系统，包括探头(1)、接收电路及波束合成模块(4，5)和弹性相关结果计算模块(72)。探头(1)在目标组织内部产生剪切波并使其经过感兴趣区域(702a,702b,702C1,702C2,702C3,702C4,702C5),对剪切波经过的感兴趣区域(702a,702b,702C1,702C2,702C3,702C4,702C5)发送追踪脉冲。接收电路及波束合成模块(4，5)接收追踪脉冲的回波信息。弹性相关结果计算模块(72)根据追踪脉冲的回波信息进行剪切波参数的计算，获得感兴趣区域(702a,702b,702C1,702C2,702C3,702C4,702C5)对应的弹性测量结果(C)，记录弹性测量结果(C)与统计变量之间的对应关系并产生图形标记(715，716，Sa,Sb,SC1,SC2,SC3,SC4,SC5,SC1’、SC2’、SC3’、SC4’、SC5’,719a,719b,720)，其中由弹性测量结果(C)确定图形标记(715，716，Sa,Sb,SC1,SC2,SC3,SC4,SC5,SC1’、SC2’、SC3’、SC4’、SC5’,719a,719b,720)的属性。还公开了一种超声弹性测量显示方法。该方法和系统，可以提供更加直观、参考性更强的弹性测量统计数据。
