Abstract

We have studied control of microbubbles(MBs) using ultrasound for medical applications. In trials for inducement of MBs, the tolerance of radiating point was as small as 1.5 mm. Considering the motions of the human body, to apply in vivo may be difficult. Thus, using 2D-array transducer, we tried design and examination of acoustic fields which have wider MBs control region. We used Yshaped channel and radiated 4 patterns of single-focus acoustic field, aims each of the 2 x 2 points with pitch of 2.5 mm, by time division with 1 ms intervals. Result, designed acoustic field could have the tolerance of radiating point of 6 mm. MBs control region might be expanded by time division method.
