Outline of Final Research Achievements

Since the acoustic energy is dispersed with the multiple focal points, it was difficult to obtain sufficient displacement. Using two ultrasound array transducers (128 elements), which realizes not only the spatial design but also the dynamic variation of acoustic field, we realized the bending of a thin catheter by forming multiple focal points. We realized to bend the thin catheter with about 0.3 mm by introducing tempo-spatial division emission of single focal point.
