Abstract
A method and apparatus by which deceases are identified uses computer analysis of sound signals that are picked up from various locations on the chest walls of a subject by a modified stethoscope. The modification includes a small microphone in one of the hoses of the stethoscope. Signals from the microphone are input to a computer such as a personal computer or PC for processing. The computer extracts from these signals features which are dominant for particular diseases. A classifier classifies these features, determines if the lungs are diseased, and identifies the disease.

A method of identifying a disease that produces sounds that are characteristic of the disease, comprising:
- subjecting the sounds to a plurality of multi-dimensional, multi-parameter feature space analyses to identify a plurality of multi-dimensional features associated with the sounds;
- and
- selecting from among the plurality of multi-dimensional features, only dominant features that identify the disease by using discriminant analysis.
An apparatus for identifying a disease that produces sounds that are characteristic of the disease, the apparatus comprising:
- a stethoscope for acquiring the sounds from the subject;
- a transducer operatively connected to the stethoscope for converting the sounds to signals;
- and
- a computer-based analyzer for analyzing the signals to identify the disease, a computer-based analyzer identify the disease by subjecting the signals to multi-dimensional, multi-parameter feature space analysis to identify a plurality of multi-dimensional features associated with the sounds, and selecting from among the plurality of multi-dimensional features, only dominant multi-dimensional features that identify the disease by using discriminant analysis.
An apparatus for identifying a disease in a subject, the disease producing sounds that are characteristic of the disease, the apparatus comprising:
- means for acquiring the sounds;
- and
- a computer-based analyzer for analyzing the sounds to identify the disease by subjecting the sounds to multi-dimensional, multi-parameter feature space analysis to identify a plurality of multi-dimensional features associated with the sounds, and selecting from among the plurality of multi-dimensional features, only dominant multi-dimensional features that identify the disease by using discriminant analysis.
