Title (EN) ACOUSTIC VARIABLE FOCAL LENGTH LENS ASSEMBLY
(FR) ASSEMBLAGE DE LENTILLES A DISTANCE FOCALE ACOUSTIQUE VARIABLE
Abstract: front page image
(EN)A lens assembly (100) is comprised of a physical acoustic lens (106) having a fixed relatively short focal length serially spaced from an electronic acoustic lens (114) having any selected one of a plurality of different relatively long focal lengths. Such a lens assembly is suitable for use in a pulse-echo ultrasonic-imaging system for imaging a deep structure (102).
(FR)Un assemblage de lentilles (100) comprend une lentille acoustique physique (106) ayant une distance focale fixe relativement petite espacee en serie d"une lentille acoustique electronique (114) dont une distance focale, parmi la pluralite de distances focales relativement longues qu"elle possede, a ete selectionnee. Un tel assemblage de lentilles est approprie pour etre utilise dans un systeme d"images ultrasonore a retours d"impulsions pour mettre en image une structure profonde (102).
