Abstract

ECHOGRAPHE A ULTRASONS EMETTANT DES IMPULSIONS PAR UNE SONDE 1 MONTEE SUR UN PANTOGRAPHE COMPRENANT DES TIGES ARTICULEES 41 ET 42. LA SONDE SE COMPOSE D'UN RESEAU DE TRANSDUCTEURS A BALAYAGE ELECTRONIQUE AVEC FOCALISATION DYNAMIQUE. UN MICROPROCESSEUR RECOIT LES VALEURS DES POSITIONS ANGULAIRES DES TIGES 41 ET 42 ET DE L'ANGLE DE ROTATION DE LA SONDE ET COMMANDE LE BALAYAGE ELECTRONIQUE. LES INFORMATIONS CONCERNANT LES ECHOS VENANT DES POINTS M (X, Y) SONT MISES EN MEMOIRE ET TRAITEES AVANT VISUALISATION. APPLICATION A L'EXPLORATION DE L'INTERIEUR DU CORPS D'UN PATIENT EN VUE DE L'ETABLISSEMENT D'UN DIAGNOSTIC MEDICAL.
