Title
(EN) ULTRASOUND METHOD AND APPARATUS FOR CHARACTERIZING AND IDENTIFYING BIOLOGICAL TISSUES
(FR) PROCÉDÉ ET APPAREIL À ULTRASONS POUR CARACTÉRISER ET IDENTIFIER DES TISSUS BIOLOGIQUES
Abstract
(EN)
A method and apparatus are disclosed for characterizing and identifying tissues in a given body part using a transmitted ultrasound signal, wherein the method comprises receiving an ultrasound signal in response to the transmission of the transmitted ultrasound signal toward the given body part, computing an attenuation coefficient for the received ultrasound signal, the attenuation coefficient being indicative of the attenuation of the transmitted ultrasound signal in the tissue and identifying the tissue using the computed attenuation coefficient.
(FR)
La présente invention concerne un procédé et un appareil qui servent à caractériser et à identifier des tissus dans une partie du corps donnée au moyen d'un signal ultrasonique émis, le procédé consistant à recevoir un signal ultrasonique en réponse à l'émission de ce signal en direction de la partie du corps donnée, à calculer un coefficient d'atténuation pour le signal ultrasonique reçu, ce coefficient étant représentatif de l'atténuation du signal ultrasonique émis dans le tissu, et à identifier le tissu au moyen du coefficient d'atténuation calculé.
