Abstract
(EN)
Three ultrasonic transmissions of positive, negative and negative polarities are executed for each of a plurality of ultrasonic scan lines on the basis of a predetermined rate period. Echo signals generated due to the respective ultrasonic transmissions are received at the same rate. For each scanning line, addition of the echo signal based on the first ultrasound of positive polarity to the echo signal based on the second ultrasound of negative polarity produces a normal mode image. Also for each scanning line, addition of the echo signal based on the first ultrasound of positive polarity to the echo signal based on the third ultrasound of negative polarity produces centesis mode image data. The produced images of normal and centesis modes are displayed in a predetermined manner.
(FR)
Trois émissions d’ultrasons de polarité positive, négative et négative sont réalisées pour chacune d’une pluralité de lignes de balayage par ultrasons sur la base d’une période de taux prédéterminé. Des signaux d’écho générés dus aux émissions respectives d’ultrasons sont reçus au même taux. Pour chaque ligne de balayage, l’addition du signal d’écho basé sur les premiers ultrasons de polarité positive et du signal d’écho basé sur les deuxièmes ultrasons de polarité négative produit une image en mode normal. De même, pour chaque ligne de balayage, l’addition du signal d’écho basé sur les premiers ultrasons de polarité positive et du signal d’écho basé sur les troisièmes ultrasons de polarité négative produit des données image en mode centèse. Les images produites en mode normal et en mode centèse sont affichées de manière prédéterminée.

 複数の超音波走査線の各々に対して、所定のレート周期を基準として、正、負、負の各極性にて3回の超音波送信を実行し、同レートにより、上記送信超音波のそれぞれに起因して発生したエコー信号を受信する。各走査線において、1回目の正極性の超音波に基づくエコー信号と2回目の負極性の超音波に基づくエコー信号とを加算することで、通常モード画像を生成する。また、各走査線において、1回目の正極性の超音波に基づくエコー信号と3回目の負極性の超音波に基づくエコー信号とを加算することで、穿刺モード画像データを生成する。生成された通常モード画像及び穿刺モード画像は、所定の形態にて表示される。
