Method and system for analyzing cardiovascular sounds
First Claim
1. A system for analyzing sounds originating in at least a portion of an individual'"'"'s cardiovascular system comprising:
- (One) N transducers, where N is an integer, each transducer configured to be fixed on a surface of the individual over the thorax, the ith transducer being fixed at a location xi and generating an initial signal P(xi,t) indicative of pressure waves at the location xi, for i=1 to N; and
(Two) a processor configured to receive the signals P(xi,t) and to filter the signals P(xi,t) 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.

Abstract
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,i) indicative of pressure waves at the location xi, for i=1 to N. the signals P(xi,t) are processed 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.
