When containment real time Characteristic, everything it makes the blowhole conversion contrast medium visualize which exists in the systematic fault scope distinguishing only the contrast medium origin signal which is generated with that securely, to image it converts. It irradiates the transmission beam to the suffering inspection body which prescribes the ultrasonic contrast medium from probe, 1 the systematic coaxial tomography the multiple transmission beams which had the focal length which differs to the occasion where you obtain, from those whose focal length is long it irradiates to sequence making use of the reception echo which accompanies this transmission, it does amendment operation in the reception echo signal which accompanies that, by the fact that it adds in difference taking of the reception beam immediately before and addition treatment section 11 in difference operation section 14, it makes blowhole conversion contrast medium everything visualize which exists in the target region, selects only the contrast medium component and to image converts.リアルタイム性を保持した状態で、組織断層画面中において存在する気泡化造影剤を全て可視化させ、それによって発生した造影剤由来信号のみを確実に区別して画像化する。超音波造影剤を投与した被検体に探触子1から送信ビームを照射し、この送信に伴う受信エコーを用いて組織断層像得る際に、異なる焦点距離を持った複数の送信ビームを焦点距離の長いものから順に照射し、それに伴った受信エコー信号に補正演算をし、差分演算部14において直前の受信ビームとの差分とり、積算処理部11で積算することで、対象部位に存在する気泡化造影剤全てを可視化させ、その造影剤成分のみを抽出し画像化する。
