Title
(EN) ULTRASONIC MEASUREMENTS FOR RECONSTRUCTING AN IMAGE OF AN OBJECT
(FR) MESURES ULTRASONORES POUR RECONSTRUIRE UNE IMAGE D'UN OBJET
Abstract
(EN)
Teachings disclosed herein provide a method for performing multiple measurements of an object. The first method comprises the step of providing a plurality of non-focused excitation signals, receiving a plurality of response signals and reconstructing image based on the received signals. A second method serves for a reconstruction of an image of an object based on received signals and prior knowledge, wherein information available twice within the prior knowledge and the received signals are removed before reconstructing. A third method refers to the performing of multiple measurements of an object. This third method comprises the steps of performing a first measurement starting with reconstruction based on the first measurement, performing a second measurement and continuing the reconstruction based on the first and second measurement. A fourth aspect refers to a combiner comprising a plurality of interfaces for a plurality of ultrasonic transducers, a computer interface and a mixer.

La présente invention concerne un procédé pour la réalisation de mesures multiples d'un objet. Le premier procédé comprend l'étape consistant à fournir une pluralité de signaux d'excitation non focalisés, recevoir une pluralité de signaux de réponse et reconstruire une image sur la base des signaux reçus. Un deuxième procédé sert pour une reconstruction d'une image d'un objet sur la base de signaux reçus et de connaissances préalables, des informations disponibles deux fois dans les connaissances préalables et les signaux reçus étant éliminées avant la reconstruction. Un troisième procédé concerne la réalisation de mesures multiples d'un objet. Ledit troisième procédé comprend les étapes consistant à effectuer une première mesure débutant avec la reconstruction sur la base de la première mesure, effectuer une seconde mesure et continuer la reconstruction sur la base des première et seconde mesures. Un quatrième aspect de l'invention concerne un combineur comprenant une pluralité d'interfaces pour une pluralité de transducteurs ultrasonores, une interface d'ordinateur et un mélangeur.
