Abstract

Abstract Translated from French Sonde à ultrasons et échographe à balayage sectoriel statique notamment pour image à grand angle. Selon un mode de réalisation possible, la sonde comporte plusieurs groupes (G1, G2, G3) d'éléments transducteurs (Ti) faisant entre eux des angles obtus (â) de façon à définir globalement un contour convexe de sorte que les retards nécessaires pour obtenir un balayage complet soient plus faibles qu'avec une barrette linéaire classique et donc plus faciles à maîtriser. Application à l'échographie médicale. Static sector scanning ultrasound probe and ultrasound scanner, especially for wide angle images. According to one possible embodiment, the probe comprises several groups (G1, G2, G3) of transducer elements (Ti) forming between them obtuse angles (â) so as to define a generally convex contour so that the delays necessary for to obtain a complete sweep are weaker than with a conventional linear bar and therefore easier to control. Application to medical ultrasound.
