Abstract
Appareil médical d'examen de tissus par ultrasons, comprenant un récipient contenant un liquide de couplage intercalé entre l'émetteur d'ultrasons et les tissus à examiner. La vitesse de propagation des ondes acoustiques dans ce liquide de couplage est nettement inférieure à la vitesse de propagation des memes ondes dans les tissus. Cet appareil est destiné à l'examen, sans injection, de tissus à l'intérieur du corps d'un sujet
