Title (EN) ULTRASONIC PROBE AND ULTRASONIC IMAGING APPARATUS
(FR) SONDE ULTRASONORE ET APPAREIL D'IMAGERIE ULTRASONORE
(JA) 超音波探触子及び超音波撮像装置
Abstract: front page image
(EN)An ultrasonic probe and ultrasonic imaging apparatus, wherein the artifacts from transverse waves generated at the substrate of a capacitive micro-machined ultrasonic transducer are reduced. The substrate thickness of the ultrasonic transducer is set to a suitable range so that the energy of the transverse waves within the sensitive band (91) of the ultrasonic transducer is efficiently emitted to the outside, thereby reducing artifacts in ultrasonic imaging.
(FR)L'invention porte sur un appareil d'imagerie ultrasonore et sur une sonde ultrasonore, les artéfacts provenant d'ondes transversales générées au niveau du substrat d'un transducteur ultrasonore micro-usiné capacitif étant réduites. L'épaisseur de substrat du transducteur ultrasonore est fixée à une plage acceptable de telle sorte que l'énergie des ondes transversales à l'intérieur de la bande sensible (91) du transducteur ultrasonore est émise de manière efficace vers l'extérieur, réduisant ainsi les artéfacts dans l'imagerie ultrasonore.
(JA) 静電容量型マイクロマシン超音波トランスデューサの基板に発生する横波によるアーチファクトを低減する。 超音波トランスデューサの基板厚を最適な範囲に設定し、超音波トランスデューサの感度帯域91内の横波のエネルギーを効率的に外部に放射し横波を減衰させることで、超音波撮像におけるアーチファクトの低減を図る。
