Abstract
A method and system for analyzing respiratory tract sounds in an individual. A plurality of N transducers are fixed over the thorax. The ith transducer is fixed at a location xi, and generates a signal P(xi,t) indicative of pressure waves at the location xi, for i=1 to N. A processor receives the signals P(xi,t) and determines an average acoustic energy {tilde over (P)}(x,t1,t2) at at least one position x over a time interval where {tilde over (P)}is determined in an algorithm involving at least one of the signals P(xi,t).
Claims31
A system for analyzing sounds in at least a portion of an individual's respiratory tract comprising:
- (a) a plurality of N transducers, 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 a signal P(xi, t) indicative of pressure waves at the location xi;
- for i=1 to N;
- and
- (b) a processor configured to receive the signals P(xi,t) and determine an average acoustic energy {tilde over (P)}(x, t1, t2) at at least one position x over a time interval from a first time t1 to a second time t2, {tilde over (P)} being determined in an algorithm involving at least one of the signals P(xi,t).
A method for analyzing sounds in at least a portion of an individual's thorax, comprising:
- (One) obtaining N signals P(xi,t) for i=1 to N, the signal P(xi,t) being indicative of pressure waves at the location xi;
- on a surface of the body over the thorax;
- (Two) determining an average acoustic energy {tilde over (P)}(x,t1,t2)at at least one position x over a time interval from a first time t1 to a second time t2, {tilde over (P)} determined in an algorithm involving at least one of the signals.
A program storage device readable by machine, tangibly embodying a program of instructions executable by the machine to perform method steps comprising determining for at least one time interval, an average acoustic energy function {tilde over (P)} using an algorithm involving at least one signal P(xi,t) indicative of pressure waves at a location xi on a body surface.
A computer program product comprising a computer useable medium having computer readable program code embodied therein analyzing sounds in at least a portion of an individual's body, the computer program product comprising:
- computer readable program code for causing the computer to determine, for at least one time interval, an acoustic energy function {tilde over (P)}, {tilde over (P)} being determined in algorithm involving at least one signal P(xi,t) indicative of pressure waves at a location xi on a body surface.
