我们报告了通过声辐射力主动选择微泡路径的尝试，其中我们研究了通过使用矩阵阵列换能器形成连续波的多个焦点来控制微泡。然而，由于这些焦点的位置是沿着声压斜率扫过微气泡，因此很难逆着流动方向集中微气泡。为了产生吸引力来集中流动中的微气泡，我们形成了两个具有相位变化的焦点的分时声场。我们成功地利用两个相位相反的焦点将微气泡集中在水流中，在细通道中清晰地确认了微气泡的流线。此外，我们还使用具有 Y 形分叉的人造血管确认了感应性能，其中计算了所需路径的感应率，并根据分时声场中焦点的发射模式进行变化。
We have reported our attempts for active path selection of microbubbles by acoustic radiation forces, where we have investigated to control microbubbles by forming multiple focal points of continuous wave using a matrix array transducer. However, because those focal points were located to sweep microbubbles along the slope of sound pressure, it was difficult to concentrate microbubbles against the direction of flow. To produce attractive force to concentrate microbubbles in flow, we formed time-shared acoustic field of two focal points with phase variation. We have succeeded to concentrate microbubbles in water flow utilizing two focal points with opposite phase, where streamline of microbubbles was clearly confirmed in a thin channel. Also we confirmed induction performance using an artificial blood vessel with Y-form bifurcation, where induction rate to a desired path was calculated and varied according to the emission pattern of the focal points in time-shared acoustic fields.
