Abstract

L'invention se rapporte à un procédé et circuit (100) de pilotage et d'alimentation de transducteurs ultrasonores à capacité commutée synchrone, contrôlé par boucle numérique. Ce circuit (100) comprend une interface de puissance (106) commandée par un générateur de signal carré ou rectangulaire multi-niveaux (102). Ce dispositif comprend un circuit d’accordage (104) qui est commandé par un circuit de commande d'accordage (109) pour présenter, avec le transducteur, une fréquence propre déterminée. Typiquement, cette adaptation comprend en entrée une inductance (L1) en série, et en sortie une capacité (C1) à connexion commandée (K1) montée en parallèle avec le transducteur (302). Cette connexion (K1) est commandée selon une différence de phase détectée (Δφ12) constatée entre l'entrée (φ1) et la sortie (φ2) de ladite inductance (L1). Elle est avantageusement asservie pour fournir une différence de phase valant π/2. L'invention se rapporte en outre à un élément ultrasonique, une tête ultrasonique, et un système ultrasonique d'imagerie et/ou de traitement, notamment médical. Abrégé : voir Fig.2
