Title
(EN) TWO-DIMENSIONAL TRANSDUCER INTEGRATED CIRCUIT
(FR) CIRCUIT INTEGRE POUR TRANSDUCTEURS BIDIMENSIONNELS
Abstract
(EN)
A data acquisition and display apparatus (10) for an ultrasonic camera includes an ultrasonic scanning head (61) for scanning an ultrasonic field of view in two dimensions. A timing and digitizing apparatus (14) for digitizing ultrasonic signals from the ultrasonic scan head (61) has a digitized output. An interface (16) is coupled between the timing and digitizing apparatus (14) and a graphics engine (24) and first and second digital signal processors (20, 22). A graphics processor (24) is coupled to the graphics data line. The system (10) also includes an image processor (28) and computer controller (18) which controls the graphics and digital signal processors (20, 22, 24).

Un dispositif d'acquisition et d'affichage de données (10), destiné à une caméra à ultrasons, comporte une tête de balayage ultrasonore (61) qui balaie un champ de vision ultrasonore en deux dimensions. Un dispositif de chronométrage et de numérisation (10) numérise des signaux ultrasonores provenant de cette tête de balayage (61) et donne un signal de sortie numérisé. Une interface (16) est connectée entre ce dispositif de chronométrage et de numérisation (14) et un processeur graphique (24) ainsi qu'un premier et un deuxième processeurs de signaux numériques (20, 22). Le processeur graphique (24) est connecté à la ligne de données graphiques. Ce dispositif (10) comporte aussi un processeur d'images (28), et un circuit de commande informatisé (18) qui commande les processeurs graphiques et de signaux numériques (20, 22, 24).
