Transducer (T n) it discharges the ultra wave into the observation territory which includes the minute bubble from T,1 in parallel with the discharge of the ultra wave and it depends on destroying the minute bubble individually, it is method of ultrasonic picture converting the high resolution. Echo signal S of the not yet processing which is received every discharge j of the ultra wave, by each transducer i j (i, t) is recorded, the differential signal V j which displays the change between the signals of the not yet processing which is continued next (i, t) is decided, parabola function P j (x) is fitted by the differential signal which corresponds to each forwarding j, apex A of this function P j which corresponds to the position of the minute bubble which next is destroyed with forwarding j 1 and j j (x0, y0) is decided.トランスデューサ(T1からTn)が微小な泡を含む観察領域内に超音波を放出し、超音波の放出と並行して個別に微小泡を破壊することによる、高解像度の超音波画像化の方法である。超音波の放出jごとに、各トランスデューサiによって受信された未処理の反響信号Sj(i,t)が記録され、次いで連続する未処理の信号間の変化を表す差分信号Vj(i,t)が決定され、放物線関数Pj(x)が各送出jに対応する差分信号にフィットされ、次いで送出j-1とjとの間に破壊された微小な泡の位置に対応するこの関数Pjの頂点Aj(x0,y0)が決定される。
