    • Method of ultrasound imaging in which vibration-induced localised (LOVIT) displacements code the ultrasound signal at the place of origin, enabling clutter cancellation. The require displacements can be induced by an acoustic radiation force (ARF) generated by an ultrasonic focused beam. One possibility for ARF-LOVIT is to acquire one photoacoustic (PA) image prior to the ARF push, and a second image immediately after the push when the non-zero displacement transient at the focus region is present. A difference image then highlights the signal from optically absorbing structures located inside the displacement region. Direct clutter, in contrast, originates from outside the imaged region where no displacement occurs, and is thus estimated. Echo clutter from acoustic scattering at echogenic structures inside the displacement region also shows up on the difference image, but at a different depth from where it was generated owing to the additional acoustic round-trip time as compared to PA signals.
    • 超声波成像方法,其中振动诱导的局部(LOVIT)位移在原点处对超声信号进行编码,从而实现杂波消除。 要求位移可以由由超声波聚焦光束产生的声辐射力(ARF)引起。 ARF-LOVIT的一种可能性是在ARF推动之前获取一个光声(PA)图像,并且当存在在聚焦区域处的非零位移瞬变时紧接在推动之后的第二个图像。 然后,差分图像突出了位于位移区域内的光学吸收结构的信号。 相比之下,直接杂波源于没有位移发生的成像区域的外部,因此被估计。 在位移区域内的回声结构的声散射的回波杂波也出现在差分图像上,但是与PA信号相比,由于额外的声学往返时间,与其产生的深度不同。
