Acoustic window identification
First Claim
Patent Images
1. A method for determining an acoustic window suitable for passive-acoustic coronary artery disease evaluation, comprising the steps of:
- (a) positioning a multi-channel acoustic sensor array onto the chest of a subject;
(b) calculating a weighted signal value for each of the sensor channels in the multi-channel sensor array;
(c) determining the location of each sensor corresponding to the sensor channel in the array;
(d) identifying the sensor channels which meet predetermined test criteria; and
(e) defining a perimeter which substantially extends about and encloses therewithin the sensors associated with the sensor channels identified in step (d), thereby defining an acoustic window suitable for acoustic listening diagnostic procedures.

Abstract
Methods for identifying and/or visualizing an acoustic window suitable for passive acoustic coronary heart disease evaluations by mapping the relative SNR distribution on the channels on an array of a plurality of sensors to nominal locations on a person'"'"'s chest of each sensor in the acoustic sensor array and identifying a plurality of sensor locations that correspond to the highest channel SNR'"'"'s is described and/or sizing the acoustic sensor array to correspond with the identified acoustic window.
