Abstract
L'INVENTION CONCERNE UN DISPOSITIF DE FORMATION D'IMAGE PAR ULTRASONS A FOCALISATION DYNAMIQUE ET PSEUDO-DYNAMIQUE. IL COMPORTE UN RESEAU D'ELEMENTS EN PHASE 32 ASSOCIES CHACUN AVEC UN CANAL DE SIGNAUX. CHAQUE CANAL COMPORTE UN CIRCUIT A RETARD 36 ET LES RETARDS INTRODUITS SONT REGLES DE MANIERE A ORIENTER LE FAISCEAU ACOUSTIQUE. DE PLUS, LE GAIN DE PAIRES EXTERIEURES SYMETRIQUES D'ELEMENTS DU RESEAU EST REDUIT POUR LES ECHOS PROCHES 4, 8, 50 AFIN DE DIMINUER L'OUVERTURE EFFECTIVE DU RESEAU ET DE CONSERVER UNE BONNE RESOLUTION DANS LE CHAMP PROCHE. L'INVENTION S'APPLIQUE NOTAMMENT AU DIAGNOSTIC MEDICAL.
