A method and system for analyzing sounds originating in at least a portion of an individual~s cardiovascular system. N transducers, where N is an integer, are fixed on a surface of the individual over the thorax. The ith transducer is fixed at a location xi and generates an initial signal P(xi,t) indicative of pressure waves at the location xi; for i=1 to N. the signals P(xi,t)are processes so as to generate filtered signals in which at least one component of the signals P(xi,t)not arising from cardiovascular sounds has been removed. The filtered signals may be used for generating an image of the at least portion of the cardiovascular system.
La présente invention concerne un procédé et un système d'analyse des sons provenant au moins d'une partie du système cardiovasculaire d'un individu. N transducteurs sont fixés sur une surface de l'individu au-dessus du thorax, "N" étant un entier. Le i?ème¿ transducteur, qui est fixé en un emplacement x¿i?, génère un signal initial P(x¿i?,t) indiquant les ondes de pression à l'emplacement x¿i?, "i" valant de 1 à N. Les signaux P(x¿i?,t) sont traités de façon à générer des signaux filtrés dans lesquels une composante au moins des signaux P(x¿i?,t) ne provenant pas des sons cardiovasculaires a été éliminée. Les signaux filtrés peuvent servir à produire une image de la partie considérée du système cardiovasculaire.
