Abstract

L'invention concerne un appareil de diagnostic par ultrasons destiné à l'examen d'un corps vivant. Il comporte un émetteur et un récepteur d'ultrasons ainsi qu'un dispositif de visualisation d'image. Le récepteur comporte un détecteur dont les signaux sont utilisés, en plus de la visualisation de l'image, pour indiquer la dose totale d'énergie ultrasonore à laquelle le corps vivant a été soumis. L'appareil donne également une alarme lorsque la dose totale dépasse une limite prédéterminée. Application au diagnostic médical.
