Abstract: An ultrasonic diagnostic system is provided which detects the presence of coated microbubble contrast agents in the body of a patient by transmitting ultrasonic energy which causes the destruction of the coated microbubbles and detects the microbubble destruction through phase insensitive detection and differentiation of echoes received from two consecutive ultrasonic transmissions. The destruction of a microbubble can also be used as a point source of acoustic energy for aberration correction, whereby the timing of the beamformer is adjusted from an analysis of beamformer signals resulting from a detected microbubble destruction event.

Abstract translation: 用于通过超声波询问来检测患者体内涂覆的微泡造影剂的存在的方法包括以足以引起涂覆的微气泡的破坏的能量水平将超声波脉冲传输到患者体内。 接收每个脉冲传输后返回的信号，并通过相位不敏感检测进行检测。 在两个脉冲传输之后接收到的检测信号在空间上是有区别的，并且超过预定阈值的信号差异被识别为由微泡破坏事件导致的。 差异化包括从在较早的脉冲传输之后在空间基础上接收的信号中减去稍后脉冲传输之后接收的信号，并且从被询问的场中的相同位置接收每个相减对的信号。
