Title (EN) ULTRASONIC IMAGING DEVICE
(FR) DISPOSITIF D'IMAGERIE À ULTRASONS
(JA) 超音波撮像装置
Abstract: front page image
(EN)The waveform of an ultrasonic wave transmitted by a capacitive micro-machined ultrasonic transducer is controlled to improve transmitted sound pressure. The asymmetric waveform of the transmitted ultrasonic wave is made variable according to the voltage value.
(FR)La présente invention concerne un dispositif d'imagerie dans lequel la forme d'onde d'une onde ultrasonore transmise par un transducteur ultrasonore micro-usiné capacitif est contrôlée pour améliorer la pression sonore transmise. La forme d'onde asymétrique de l'onde ultrasonore transmise devient variable en fonction de la valeur de tension.
(JA) 静電容量型マイクロマシン超音波トランスデューサが送信する超音波の波形を制御し、送信音圧を向上する。  送信超音波について、正負非対称波形を電圧値に応じて可変にする。
