Title
(EN) MEMS-SWITCHED ULTRASONIC TRANSDUCER ARRAY WITH IMPROVED RELIABILITY
(FR) RÉSEAU DE TRANSDUCTEURS ULTRASONORES COMMUTÉS PAR SYSTÈMES MICROÉLECTROMÉCANIQUES (MEMS) À FIABILITÉ AMÉLIORÉE
Abstract
(EN)
Various approaches for improving reliability in an ultrasound system having transducer elements, phase transmission lines, and a switch matrix having beamforming switches for connecting the phase transmission lines to the transducer elements involve operating the beamforming switches to avoid "hot" switching as the activation pattern of the transducers changes.
(FR)
Selon l'invention, diverses approches pour améliorer la fiabilité dans un système ultrasonore ayant des éléments transducteurs, des lignes de transmission de phase, et une matrice de commutation ayant des commutateurs de formation de faisceau pour connecter les lignes de transmission de phase aux éléments de transducteur mettent en jeu le fonctionnement des commutateurs de formation de faisceau pour éviter une commutation "à chaud" lorsque le motif d'activation des transducteurs change.
