Title:
バイアス極性ビームプロフィール制御を有する微細加工された超音波トランスデューサ
Document Type and Number:
Japanese Patent JP2006519556
Kind Code:
A
Abstract:
A capacitive microfabricated ultrasonic transducer with control of elevation phase through alternating bias polarity is disclosed. Such control of elevation phase results in simple ultrasonic probes with excellent slice thickness attributes. Furthermore, tight spatial variation of phase results in an effective way to achieve transmit aperture and apodization control. Further still, such capacitive microfabricated ultrasonic transducers can achieve elevation focus without the need of a lossy mechanical lens.
